+# Env 用户手册
+
+Env 是 RT-Thread 推出的开发辅助工具，针对基于 RT-Thread 操作系统的项目工程，提供编译构建环境、图形化系统配置及软件包管理功能。
+
+其内置的 menuconfig 提供了简单易用的配置剪裁工具，可对内核、组件和软件包进行自由裁剪，使系统以搭积木的方式进行构建。
+
+## 主要特性
+
+- menuconfig 图形化配置界面，交互性好，操作逻辑强；
+- 丰富的文字帮助说明，配置无需查阅文档；
+- 使用灵活，自动处理依赖，功能开关彻底；
+- 自动生成 rtconfig.h，无需手动修改；
+- 使用 scons 工具生成工程，提供编译环境，操作简单；
+- 提供多种软件包，模块化软件包耦合关联少，可维护性好；
+- 软件包可在线下载，软件包持续集成，包可靠性高；
+
+## 准备工作
+
+Env 工具包含了 RT-Thread 源代码开发编译环境和软件包管理系统。
+
+- 从 RT-Thread 官网下载 [Env 工具](https://www.rt-thread.org/page/download.html)。
+- 在电脑上装好 git，软件包管理功能需要 git 的支持。git 的下载地址为`https://git-scm.com/downloads`，根据向导正确安装 git，并将 git 添加到系统环境变量。
+- 注意在工作环境中，所有的路径都不可以有中文字符或者空格。
+
+## Env 的使用方法
+
+### 打开 Env 控制台
+
+RT-Thread 软件包环境主要以命令行控制台为主，同时以字符型界面来进行辅助，使得尽量减少修改配置文件的方式即可搭建好 RT-Thread 开发环境的方式。
+打开 Env 控制台有两种方式：
+
+#### 方法一：点击 Env 目录下可执行文件
+
+进入 Env 目录，可以运行本目录下的 `env.exe`，如果打开失败可以尝试使用 `env.bat`。
+
+#### 方法二：在文件夹中通过右键菜单打开 Env 控制台
+
+Env 目录下有一张 `Add_Env_To_Right-click_Menu.png`(添加 Env 至右键菜单.png) 的图片，如下：
+
+
+
+根据图片上的步骤操作，就可以在任意文件夹下通过右键菜单来启动 Env 控制台。效果如下：
+
+
+
+> [!NOTE]
+> 注：因为需要设置 Env 进程的环境变量，第一次启动可能会出现杀毒软件误报的情况，如果遇到了 **杀毒软件误报** ，允许 Env 相关程序运行，然后将相关程序添加至白名单即可。
+
+### 编译 BSP
+
+scons 是 RT-Thread 使用的编译构建工具，可以使用 scons 相关命令来编译 RT-Thread 。
+
+#### 第一步：切换到 BSP 根目录
+
+- 打开控制台后，可以在命令行模式下使用 cd 命令切换到你想要配置的 BSP 根目录中。
+
+例如工程目录为: `rt-thread\bsp\stm32f429-apollo` ：
+
+
+
+#### 第二步：bsp 的编译
+
+- Env 中携带了 `Python & scons` 环境，只需在 `rt-thread\bsp\stm32f429-apollo` 目录中运行 `scons` 命令即可使用默认的 ARM_GCC 工具链编译 bsp。
+
+
+
+编译成功：
+
+
+
+如果使用 mdk/iar 来进行项目开发，可以直接使用 BSP 中的工程文件或者使用以下命令中的其中一种，重新生成工程，再进行编译下载。
+
+```
+scons --target=iar
+scons --target=mdk4
+scons --target=mdk5
+```
+
+更多 scons 教程，请参考 [《Scons 构建工具》](../scons/scons.md)
+
+### BSP 配置：menuconfig
+
+menuconfig 是一种图形化配置工具，RT-Thread 使用其对整个系统进行配置、裁剪。
+
+#### 快捷键介绍
+
+进入 BSP 根目录，输入 `menuconfig` 命令后即可打开其界面。 menuconfig 常用快捷键如图所示：
+
+
+
+#### 修改配置
+
+menuconfig 有多种类型的配置项，修改方法也有所不同，常见类型如下：
+
+- 开/关 型：使用空格键来选中或者关闭
+- 数值、字符串型：按下回车键后会出现对话框，在对话框中对配置项进行修改
+
+#### 保存配置
+
+选择好配置项之后按 ESC 键退出，选择保存修改即可自动生成 rtconfig.h 文件。此时再次使用 scons 命令就会根据新的 rtconfig.h 文件重新编译工程了。
+
+### 软件包管理：package
+
+RT-Thread 提供一个软件包管理平台，这里存放了官方提供或开发者提供的软件包。该平台为开发者提供了众多可重用软件包的选择，这也是 RT-Thread 生态的重要组成部分。
+
+[点击这里](https://github.com/RT-Thread-packages) 可以查看到 RT-Thread 官方的提供的软件包，绝大多数软件包都有详细的说明文档及使用示例。
+
+> 提示：截止到 2018-03-13 ，当前软件包数量达到 **40+**
+
+**package** 工具作为 Env 的组成部分，为开发者提供了软件包的下载、更新、删除等管理功能。
+
+Env 命令行输入 `pkgs` 可以看到命令简介：
+
+```
+> pkgs
+usage: env.py package [-h] [--update] [--list] [--wizard] [--upgrade]
+ [--printenv]
+
+optional arguments:
+ -h, --help show this help message and exit
+ --update update packages, install or remove the packages as you set in
+ menuconfig
+ --list list target packages
+ --wizard create a package with wizard
+ --upgrade update local packages list from git repo
+ --printenv print environmental variables to check
+```
+
+#### 下载、更新、删除软件包
+
+在下载、更新软件包前，需要先在 `menuconfig` 中 **开启** 你想要操作的软件包
+
+这些软件包位于 `RT-Thread online packages` 菜单下，进入该菜单后，则可以看如下软件包分类：
+
+
+
+找到你需要的软件包然后选中开启，保存并退出 menuconfig 。此时软件包已被标记选中，但是还没有下载到本地，所以还无法使用。
+
+- **下载** ：如果软件包在本地已被选中，但是未下载，此时输入：`pkgs --update` ，该软件包自动下载；
+- **更新** ：如果选中的软件包在服务器端有更新，并且版本号选择的是 **latest** 。此时输入： `pkgs --update` ，该软件包将会在本地进行更新；
+- **删除** ：某个软件包如果无需使用，需要先在 menuconfig 中取消其的选中状态，然后再执行： `pkgs --update` 。此时本地已下载但未被选中的软件包将会被删除。
+
+#### 升级本地软件包信息
+
+随着 package 系统的不断壮大，会有越来越多的软件包加入进来，所以本地看到 menuconfig 中的软件包列表可能会与服务器 **不同步** 。使用 `pkgs --upgrade` 命令即可解决该问题，这个命令不仅会对本地的包信息进行更新同步，还会对 Env 的功能脚本进行升级，建议定期使用。
+
+### Env 工具配置
+
+- 新版本的 Env 工具中加入了自动更新软件包和自动生成 mdk/iar 工程的选项，默认是不开启的。可以使用 `menuconfig -s/--setting` 命令来进行配置。
+
+* 使用 `menuconfig -s` 命令进入 Env 配置界面
+
+ 
+
+ 按下回车进入配置菜单，里面共有 3 个配置选项
+
+ 
+
+3 个选项分别为：
+
+* **软件包自动更新功能**：在退出 menuconfig 功能后，会自动使用`pkgs --update`命令来下载并安装软件包，同时删除旧的软件包。本功能在下载在线软件包时使用。
+
+* **自动创建 MDK 或 IAR 工程功能**：当修改 menuconfig 配置后 ，必须输入 `scons --target=xxx` 来重新生成工程。开启此功能，就会在退出 menuconfig 时，自动重新生成工程，无需再手动输入 scons 命令来重新生成工程。
+
+* **使用镜像服务器下载软件包**：由于大部分软件包目前均存放在 GitHub 上，所以在国内的特殊环境下，下载体验非常差。开启此功能，可以通过 **国内镜像服务器** 下载软件包，大幅提高软件包的下载速度和稳定性，减少更新软件包和 submodule 时的等待时间，提升下载体验。
+
+## 在项目中使用 Env
+
+### 使用 Env 的要求
+
+- menuconfig 是 RT-Thread 3.0 以上版本的特性，推荐将 RT-Thread 更新到 3.0 以上版本。
+- 目前 RT-Thread 还没有对所有的 BSP 做 menuconfig 的支持，也就是说有些 BSP 暂时还不能使用 menuconfig 来进行配置，但常用的 BSP 都已经支持。
+
+### menuconfig 中选项的修改方法
+
+如果想在 menuconfig 的配置项中添加宏定义，则可以修改 BSP 下的 Kconfig 文件，修改方法可以在网络中搜索`Kconfig语法`关键字获得详细的说明文档，也可以参考 RT-Thread 中的 Kconfig 文件或者已经支持过 menuconfig 的 BSP 中的 Kconfig 文件。
+
+### 新的项目添加 menuconfig 功能
+
+这里的新项目指的是，**还未生成 .config 和 rtconfig.h** 的全新开发的项目。因为这两个文件，只有在 menuconfig 第一次保存时才会创建。具体流程如下：
+
+ 1. 将已经支持 menuconfig 功能的 BSP 里面的 kconfig 文件拷贝到新的项目根目录中。
+ 2. 注意修改 Kconfig 中的 RTT_ROOT 值为 RT-Thread 所在目录，否则可能提示找不到 RTT_ROOT 。
+ 3. 使用 menuconfig 命令开始配置即可。
+
+### 旧项目添加 menuconfig 功能
+
+这里的旧项目指的是已经经过一段时间的开发，而且项目中存在已经修改过的 rtconfig.h文件 ，但是没有使用过 menuconfig 来配置的项目。具体流程如下：
+
+ 1. 首先备份旧项目内的 rtconfig.h 文件。
+ 2. 使用 `scons --genconfig` 命令根据已有的 rtconfig.h 生成 .config 文件，这里生成的 .config 文件保存了旧项目中 rtconfig.h 文件对项目的配置参数。
+ 3. 将已经支持 menuconfig 功能的 BSP 里面的 kconfig 文件拷贝到要修改项目的根目录中。
+ 4. 注意修改 Kconfig 中的 RTT_ROOT 值为 RT-Thread 所在目录，否则可能提示找不到 RTT_ROOT 。
+ 5. 使用 menuconfig 命令来配置我们要修改的旧项目。menuconfig 会读取第二步生成的 .config 文件，并根据旧项目的配置参数生成新的 .config 文件和 rtconfig.h 文件 。
+ 6. 对比检查新旧两份 rtconfig.h 文件，如果有不一致的地方，可以使用 menuconfig 命令对配置项进行调整。
+
+### 用户软件包管理功能
+
+实际开发项目时，开发者可能想要将已下载的软件包加入 git 管理，或者想自己管理该软件包。不希望 Env 工具再拉取该软件包的最新版本，此时可以使用用户软件包管理功能。
+
+如果用户手动将 `EasyFlash-v4.1.0` 文件夹的后缀，也就是软件包的版本号删除，修改为 `EasyFlash`，此时再次使用 `pkgs --update` 命令将不会再拉取 `EasyFlash-v4.0.0` 软件包。Env 工具此时认为 EasyFlash 软件包由用户管理，此时使用 `pkgs --force-update` 命令才可以重新拉取附带 version 的新版本软件包。
+
+
+
+## 使用 pip 扩展更多功能
+
+在 Env 环境下暂时不能直接使用 Python 提供的 pip 工具来安装更多模块。如果需要在 Env 环境下使用 pip 功能，可以按照如下方法重新安装 pip 工具：
+
+1. 从地址 https://bootstrap.pypa.io/get-pip.py 下载 get-pip.py 文件，存放在磁盘中。
+
+2. 在 **Env 环境下**执行 `python get-pip.py` 命令来重新安装 pip 工具。
+
+3. pip 工具重新安装成功后，可以使用 `pip install module-name` 命令来安装所需模块。
+
+## Env 工具使用注意事项
+
+- 第一次使用 Env 推荐去官网下载最新版本的 Env 工具，新版本的 Env 会有更好的兼容性，也支持自动更新的命令。
+- 可以使用 Env 内置命令 pkgs --upgrade 来更新软件包列表和 Env 的功能代码，这样可以最大程度避免遇到已经修复的问题。
+- Env 所在路径不要有中文或者空格存在。
+- BSP 工程所在的路径不要有中文或者空格存在。
+
+## 常见问题
+
+### Q: Env 工具出现乱码怎么办？
+
+**A:** 首先检查是否有中文路径。
+检查 chcp 命令是否加入了系统环境变量，尝试使用 chcp 437 命令将字符格式改为英文。如果提示没有 chcp 命令，则考虑是没有加入到环境变量中。
+chcp 命令所在的目录可能在 system32 目录，添加到环境变量即可。
+[Env 工具乱码问题传送门](https://www.rt-thread.org/qa/forum.php?mod=viewthread&tid=5763&page=1#pid32213) 。
+
+### Q: 提示找不到 git 命令？
+
+ 'git' is not recognized as an internal or external command, operable program or batch file.
+
+**A:** 没安装 git，需要安装 git 并加入环境变量。
+
+### Q: 提示找不到 CMD 命令？
+
+**A:** 计算机右键–>> 属性—>> 高级系统设置—->> 环境变量，`C:\Windows\System32`; 加入系统环境变量即可
+
+### Q: 运行 python 的时候提示 no module named site 怎么办？
+
+**A:** 计算机右键–>> 属性—>> 高级系统设置—->> 环境变量，在管理员的用户变量中，新建变量名为 PYTHONHOME，变量值为：`F:\git_repositories\env\tools\Python27` （是 Env 里面 Python 的安装路径），注意后面不要加 “；”，否则会无效。 如果添加 PYTHONHOME 没好，再用同样的方法添加 PYTHONPATH。就可以解决这个问题了。
+
+有一篇博文详细的描述了这个问题：[传送门在这里](http://blog.csdn.net/nullzeng/article/details/45293333)，如果想了解原理可以看一看。
+
+### Q: 在 Env 下能生成哪些类型的工程？
+
+ **A:**
+
+ 1. 目前在 Env 下可以使用 scons 工具生成 mdk/iar 的工程，还没有支持 eclipse 工程的自动生成。
+ 2. 一般在使用 Env 的开发，使用 gcc 的工具链，那么只需要一个 source insight 或者 vs code 之类的编辑器来看代码，使用 scons 编译即可。
+
+### Q: 自己制作的 BSP 如何能支持 menuconfig？
+
+**A:** 可以查阅本章 **在项目中使用 Env** 章节。
+
+### Q: pkgs --upgrade 命令和 pkgs --update 命令有什么区别？
+
+ **A:**
+
+ 1. pkgs --upgrade 命令是用来升级 Env 功能脚本本身和软件包列表的。没有最新的包列表就不能选择最近更新的软件包。
+ 2. pkgs --update 命令是用来更新软件包本身的，比如说你在 menuconfig 中选中了 json 和 mqtt 的软件包，但是退出 menuconfig 时并没有下载这些软件包。你需要使用 pkgs --update 命令，这时候 Env 就会下载你选中的软件包并且加入到你的工程中去。
+ 3. 新版本的 Env 支持 menuconfig -s/--setting 命令，如果你不想每次更换软件包后使用 pkgs --update 命令，在使用 menuconfig -s/--setting 命令后配置 Env 选择每次使用 menuconfig 后自动更新软件包即可。
+
+### Q: VC98 文件夹问题
+
+详细描述：出现错误 MissingConfiguration: registry dir `D:\Program Files (x86)\Microsoft Visual Studio\VC98` not found on the filesystem
+
+
+
+**A:** 在划线的目录新建一个 VC98 的空文件夹，就可以使用 scons 了。
+
+### Q: 使用 menuconfig 命令提示“can't find file Kconfig”。
+
+**A:** 当前工作的 BSP 目录下缺少 Kconfig 文件，参考本文《新的项目添加 menuconfig 功能》 和 《旧项目添加 menuconfig 功能》。
+
+### Q: IOError: [Errno 2] No such file or directory: 'nul'
+
+**A:** 这是由于 windows 系统没有开启 `Null Service` 服务的缘故，常见于在 win10 的早期版本中（如版本号 1703），该问题有两种解决方法，第一种是开启 windows 更新将 windows 更新到最新版本，因为在后续的补丁中 windows 默认开启了该服务，第二种是参考该 [link](http://revertservice.com/10/null/) 手动开启 `Null Service` 服务。

+# Kconfig 语法
+
+## Kconfig 简介
+
+RT-Thread 借助 Kconfig 文件生成的配置文件 rtconfig.h 来配置系统，Kconfig 文件是各种配置界面的源文件。当在 bsp 目录下使用 env 工具执行 menuconfig 命令时会出现 RT-Thread 系统的配置界面，所有配置工具都是通过读取当前 bsp 目录下的 Kconfig 文件来生成配置界面的，这个文件就是所有配置的总入口，它会包含其他目录的 Kconfig 文件。配置工具读取各个 Kconfig 文件，生成配置界面供开发人员配置系统，最终生成 RT-Thread 系统的配置文件 rtconfig.h。
+
+## Kconfig 基本语法
+
+### config 语句
+
+config 定义了一组新的配置选项
+
+以下为 RT-Thread 系统中 config 语句的示例
+
+```c
+config BSP_USING_GPIO
+ bool "Enable GPIO"
+ select RT_USING_PIN
+ default y
+ help
+ config gpio
+```
+
+以上代码对应的配置界面如下所示
+
+
+
+对应的帮助信息界面如下所示
+
+
+
+语句分析：
+- config 表示一个配置选项的开始，紧跟着的 BSP_USING_GPIO 是配置选项的名称，config 下面几行定义了该配置选项的属性。属性可以是该配置选项的
+ - 类型
+ - 输入提示
+ - 依赖关系
+ - 默认值
+ - 帮助信息
+
+- bool 表示配置选项的类型，每个 config 菜单项都要有类型定义，变量有5种类型
+ - bool 布尔类型
+ - tristate 三态类型
+ - string 字符串
+ - hex 十六进制
+ - int 整型
+- select 是反向依赖关系的意思，即当前配置选项被选中，则 RT_USING_PIN 就会被选中。
+- default 表示配置选项的默认值，bool 类型的默认值可以是 y/n。
+- help 帮助信息。
+
+通过 env 选中以上配置界面的选项后，最终可在 rtconfig.h 文件中生成如下两个宏
+
+```c
+#define RT_USING_PIN
+#define BSP_USING_GPIO
+```
+
+### 变量类型
+
+#### bool 类型
+
+布尔类型变量的取值范围是 y/n ，其使用示例如下
+```c
+config BSP_USING_WDT
+ bool "Enable Watchdog Timer"
+ select RT_USING_WDT
+ default n
+```
+
+
+上述语句对应的配置界面如下所示
+
+
+
+以上配置项在 rtconfig.h 文件中生成的宏如下所示
+
+```c
+#define BSP_USING_WDT
+#define RT_USING_WDT
+```
+
+#### string 类型
+
+字符串变量的默认值是一个字符串，其使用示例如下
+
+```c
+config RT_CONSOLE_DEVICE_NAME
+ string "the device name for console"
+ default "uart1"
+```
+
+上述语句对应的配置界面如下所示
+
+
+
+以上配置项在 rtconfig.h 文件中生成的宏如下所示
+
+```c
+#define RT_CONSOLE_DEVICE_NAME "uart1"
+```
+
+#### int 类型
+
+整型变量的取值范围是一个整型的数，其使用示例如下
+
+```c
+config BSP_I2C1_SCL_PIN
+ int "I2C1 scl pin number"
+ range 1 176
+ default 116
+```
+
+上述语句对应的配置界面如下所示
+
+
+
+以上配置项在 rtconfig.h 文件中生成的宏如下所示
+
+```c
+#define BSP_I2C1_SCL_PIN 116
+```
+
+
+#### hex 类型
+
+十六进制类型变量的取值范围是一个十六进制的数，其使用方法和整型变量用法一致，整型变量生成的是十进制的数，而十六进制生成的是十六进制的数。
+
+
+#### tristate 类型
+
+三态类型变量的取值范围是 y、n 和 m。tristate 代表在内核中有三种状态，一种是不选中，一种是选中直接编译进内核，还有一种是 m 手动添加驱动，而布尔类型变量只有两种状态，即选中和不选中。其使用方法和布尔类型变量类似。
+
+
+### menu/endmenu 语句
+
+menu 语句用于生成菜单。
+
+以下为 RT-Thread 系统中 menu/endmenu 语句的示例
+
+```c
+menu "Hardware Drivers Config"
+ config BSP_USING_COM2
+ bool "Enable COM2 (uart2 pin conflict with Ethernet and PWM)"
+ select BSP_USING_UART
+ select BSP_USING_UART2
+ default n
+ config BSP_USING_COM3
+ bool "Enable COM3 (uart3 pin conflict with Ethernet)"
+ select BSP_USING_UART3
+ default n
+endmenu
+
+```
+menu 之后的字符串是菜单名。menu 和 endmenu 间有很多 config 语句，以上代码对应的配置界面如下所示
+
+
+
+其中 Hardware Drivers Config 就是菜单名，然后进入这个菜单有 Enable COM2、Enable COM3 等选项，如下图所示
+
+
+
+
+通过 env 选中以上配置界面的所有选项后，最终可在 rtconfig.h 文件中生成如下五个宏
+
+```c
+#define BSP_USING_UART
+#define BSP_USING_UART2
+#define BSP_USING_UART3
+#define BSP_USING_COM2
+#define BSP_USING_COM3
+```
+
+### if/endif 语句
+
+if/endif 语句是一个条件判断，定义了一个 if 结构，示例代码如下
+
+```c
+menu "Hardware Drivers Config"
+ menuconfig BSP_USING_CAN
+ bool "Enable CAN"
+ default n
+ select RT_USING_CAN
+ if BSP_USING_CAN
+ config BSP_USING_CAN1
+ bool "Enable CAN1"
+ default n
+ endif
+endmenu
+```
+
+当没有选中 "Enable CAN" 选项时，下面通过 if 判断的 Enable CAN1 选项并不会显示出来，如下图所示
+
+
+
+
+当上一级菜单选中 "Enable CAN" 时
+
+
+
+
+
+
+### menuconfig 语句
+
+menuconfig 语句表示带菜单的配置项
+
+以下为 RT-Thread 系统 menuconfig 语句的示例
+```c
+menu "Hardware Drivers Config"
+ menuconfig BSP_USING_UART
+ bool "Enable UART"
+ default y
+ select RT_USING_SERIAL
+ if BSP_USING_UART
+ config BSP_USING_UART1
+ bool "Enable UART1"
+ default y
+
+ config BSP_UART1_RX_USING_DMA
+ bool "Enable UART1 RX DMA"
+ depends on BSP_USING_UART1 && RT_SERIAL_USING_DMA
+ default n
+ endif
+endmenu
+```
+
+当没有打开串口 DMA 配置时，以上代码对应的界面为
+
+
+
+当打开串口 DMA 配置时，以上代码对应的界面为
+
+
+
+语句分析：
+- menuconfig 这个语句和 config 语句很相似，但它在 config 的基础上要求所有的子选项作为独立的行显示。
+- depends on 表示依赖某个配置选项，`depends on BSP_USING_UART1 && RT_SERIAL_USING_DMA` 表示只有当 BSP_USING_UART1 和 RT_SERIAL_USING_DMA 配置选项同时被选中时，当前配置选项的提示信息才会出现，才能设置当前配置选项
+
+通过 env 选中以上配置界面的所有选项后，最终可在 rtconfig.h 文件中生成如下五个宏
+
+```c
+#define RT_USING_SERIAL
+#define BSP_USING_UART
+#define BSP_USING_UART1
+#define RT_SERIAL_USING_DMA
+#define BSP_UART1_RX_USING_DMA
+```
+
+### choice/endchoice 语句
+
+choice 语句将多个类似的配置选项组合在一起，供用户选择一组配置项
+
+RT-Thread Kconfig 文件中 choice 代码示例如下
+```c
+menu "Hardware Drivers Config"
+ menuconfig BSP_USING_ONCHIP_RTC
+ bool "Enable RTC"
+ select RT_USING_RTC
+ select RT_USING_LIBC
+ default n
+ if BSP_USING_ONCHIP_RTC
+ choice
+ prompt "Select clock source"
+ default BSP_RTC_USING_LSE
+
+ config BSP_RTC_USING_LSE
+ bool "RTC USING LSE"
+
+ config BSP_RTC_USING_LSI
+ bool "RTC USING LSI"
+ endchoice
+ endif
+endmenu
+```
+以上代码对应的配置界面为
+
+
+
+语句解析：
+- prompt 给出提示信息，光标选中后回车进入就可以看到多个 config 条目定义的配置选项；
+- choice/endchoice 给出选择项，中间可以定义多个配置项供选择，但是在配置界面只能选择一个配置项。
+
+### comment 语句
+
+comment 语句出现在界面的第一行，用于定义一些提示信息。
+
+comment 代码示例如下
+```c
+menu "Hardware Drivers Config"
+ comment "uart2 pin conflict with Ethernet and PWM"
+ config BSP_USING_COM2
+ bool "Enable COM2"
+ select BSP_USING_UART
+ select BSP_USING_UART2
+ default n
+endmenu
+```
+
+以上代码对应的配置界面为
+
+
+
+### source 语句
+
+source 语句用于读取另一个文件中的 Kconfig 文件，如：
+
+```c
+source "../libraries/HAL_Drivers/Kconfig"
+```
+
+上述语句用于读取当前 Kconfig 文件所在路径的上一级文件夹 libraries/HAL_Drivers 下的 Kconfig 文件。

+# RT-Thread Studio 快速上手
+
+## 简介
+
+此文档主要介绍如何基于 RT-Thread Studio 新建 RT-Thread 完整版工程，帮助开发者快速上手 RT-Thread Studio。
+
+本文主要内容如下
+
+- 新建 RT-Thread 工程
+
+- 修改 `main.c` 中的引脚信息
+
+- 编译、下载与验证
+
+## 创建 RT-Thread 完整版工程
+
+使用 RT-Thread Studio 新建基于 v4.0.2 的工程，界面如下图所示
+
+
+
+配置过程可总结为以下步骤：
+
+- 定义自己的工程名及工程生成文件的存放路径。
+
+- 选择`基于芯片`创建工程，选择的 RT-Thread 版本为 v4.0.2
+
+- 选择厂商及芯片型号。
+
+- 配置串口信息
+
+- 配置调试器信息
+
+工程配置完成后点击下方的`完成`按钮即可创建 RT-Thread 完整版工程。创建 nano 版工程是步骤和上述步骤一致，只需选择 RT-Thread 版本为 nano 即可，这里需要注意的是 nano 版无设备的概念。
+
+## 修改 `main.c`
+
+基于 RT-Thread 完整版创建工程时，会自动启用 PIN 设备，在 `main.c` 函数里面会自动生成如下代码
+
+```c
+/* PLEASE DEFINE the LED0 pin for your board, such as: PA5 */
+#define LED0_PIN GET_PIN(A, 5)
+
+int main(void)
+{
+ int count = 1;
+ /* set LED0 pin mode to output */
+ rt_pin_mode(LED0_PIN, PIN_MODE_OUTPUT);
+
+ while (count++)
+ {
+ /* set LED0 pin level to high or low */
+ rt_pin_write(LED0_PIN, count % 2);
+ LOG_D("Hello RT-Thread!");
+ rt_thread_mdelay(1000);
+ }
+
+ return RT_EOK;
+}
+```
+
+使用 PIN 设备时，只需要使用 `GET_PIN` 获取相应的引脚编号，并使用 `rt_pin_write` 等函数来操作引脚编号即可。
+
+例如，`stm32l475-atk-pandora` 开发板的 LED 所接的引脚为 PE7，所以修改为
+
+```c
+#define LED0_PIN GET_PIN(E, 7)
+```
+
+## 编译
+
+鼠标左键单击选中当前工程，在菜单栏单击 `为项目"quick-start"构建"Debug"`按钮即可编译工程，`quick-start` 为自己的工程名。或者使用`右键->构建项目`也可以编译工程。
+
+工程编译结果如下图
+
+
+
+## 下载
+
+工程编译无错误后即可下载程序到自己的板卡。
+
+下载程序可以通过菜单栏的`下载程序`按钮来下载。也可以通过`右键->下载程序`来进行下载，下载程序默认使用的是新建工程时选择的下载方式，如果需要更改，点击菜单栏`下载程序`按钮旁边的倒三角即可根据自己的调试器来选择下载方式。目前 Studio 支持 ST-Link 和 J-Link 这两种下载方式。选择仿真器的示例如下
+
+
+
+选择好仿真器后直接点击下载按钮即可下载
+
+程序下载结果如下图所示
+
+
+
+## 验证
+
+程序下载成功后按下开发板的复位键，并使用 Studio 菜单栏的 `Open a Terminal` 选项来打开一个串口终端，如下图所示
+
+
+
+终端中打印的信息如下
+
+
+
+从终端打印的信息中可以看到，RT-Thread 已经成功运行起来了，同时观察板载的 LED 也可以看到 LED 每隔 1 s 状态就翻转一次。
+
+## 注意事项
+
+- LED 的引脚需要根据自己的板卡进行修改
+
+- nano 版本无设备概念，所以无法使用 PIN 设备

+# RT-Thread Studio 应用开发示例 - 线程
+
+## 简介
+
+本文档将主要介绍如何基于 RT-Thread Studio 创建并启动第一个线程。
+
+## 启动第一个线程
+
+创建线程时，可以在 `main.c` 文件中加入自己创建线程的代码，也可以另外新建源文件和头文件来存放创建线程的代码，本文将以新建文件的方式创建线程。
+
+启动第一个线程的步骤主要如下
+
+- 新建源文件及头文件
+
+- 将头文件路径添加到工程
+
+- 创建线程
+
+- `main` 函数中调用
+
+
+### 新建文件
+
+创建文件夹、源文件及头文件时，可以基于 Studio 进行创建，也可以在本地创建好之后拷贝到工程路径中。这里以 Studio 新建文件为例。
+
+使用 Studio 新建文件时，参考以下步骤
+
+- 在新文件需要存放的目录下右键
+
+- 选择 `新建` 选项
+
+- 选择自己需要新建的文件类型，如：文件夹、源文件和头文件等。
+
+如下图所示
+
+
+
+
+本例中，在 application 目录下新建 `my-application` 文件夹，在该文件夹下，分别存放 `my_application.c` 源文件和 `my_applications.h` 头文件。
+
+创建文件结果如如下图所示
+
+
+
+这里需要注意的是，基于 Studio 构建工程时，Studio 会默认将工程路径下的所有源文件都参与编译，所以新建的源文件无需做任何配置即可参与工程的编译，而头文件则需要手动添加到工程中。
+
+### 添加头文件路径
+
+应用程序中如果需要包含新添加的头文件，那么就需要将新添加的头文件路径添加到工程中。添加头文件路径的过程如下
+
+- 选择菜单栏的  选项(打开构建配置)
+
+- C/C++ 构建
+
+- 设置
+
+- 如果是 C 的头文件选择 `GNU ARM Cross Compiler`，如果是汇编的头文件则选择 `GNU ARM Cross Assembler`
+
+- 选择头文件包含 `Includes`
+
+- 添加自己的头文件路径
+
+示例工程添加头文件的结果如下图所示
+
+
+
+
+### 创建线程
+
+在 `my_application.c` 文件中创建示例线程，如下代码所示
+```c
+#include <rtthread.h>
+
+#define THREAD_PRIORITY 25
+#define THREAD_STACK_SIZE 512
+#define THREAD_TIMESLICE 5
+
+/* 使用静态线程时，线程的栈需要设置字节对齐 */
+ALIGN(RT_ALIGN_SIZE)
+static rt_uint8_t thread_stack[THREAD_STACK_SIZE];
+static struct rt_thread tid1;
+
+/* 线程 1 的入口函数 */
+static void thread1_entry(void *parameter)
+{
+ rt_uint32_t count = 0;
+
+ while (1)
+ {
+ rt_kprintf("thread1 count: %d\n", count ++);
+ rt_thread_mdelay(500);
+ }
+}
+
+/* 线程示例 */
+int thread_sample(void)
+{
+ /* 静态创建线程 */
+
+ /* 初始化线程 1，名称是 thread1，入口是 thread1_entry*/
+ rt_thread_init(&tid1,
+ "thread1",
+ thread1_entry,
+ RT_NULL,
+ thread_stack,
+ THREAD_STACK_SIZE,
+ THREAD_PRIORITY,
+ THREAD_TIMESLICE);
+ /* 启动线程 */
+ rt_thread_startup(&tid1);
+
+ return 0;
+}
+```
+
+在 `my_application.h` 头文件中加入函数声明
+```c

+# RT-Thread Studio 应用开发示例 - 串口设备
+
+## 简介
+
+在 RT-Thread 中设备的开发总体上可以分为两类：设备的驱动开发和设备的应用开发。
+
+- 设备驱动开发的主要工作是操作硬件，对接设备驱动框架，并注册设备到系统中。
+
+- 设备应用开发的主要工作是直接调用操作系统提供的接口，例如：`rt_device_find`、`rt_device_open` 等函数，完成上层的业务逻辑。
+
+所以在 RT-Thread 中，对于一个具体的设备，其自底向上的开发流程可总结为如下步骤
+
+- 打开设备驱动框架支持
+
+- 对接设备驱动框架提供的接口函数
+
+- 注册设备到系统中
+
+- 使用操作系统提供 API 操作设备
+
+流程图如下所示
+
+
+
+## 新增设备
+
+本文将以串口为例，主要讲解串口设备的应用开发。串口设备驱动的开发和新增串口设备请参考 [串口设备驱动开发](https://www.rt-thread.org/document/site/rtthread-studio/drivers/uart/v4.0.2/rtthread-studio-uart-v4.0.2/)
+
+## 查找设备
+
+使用设备前需要确保系统中已经成功注册了该设备，查找设备是否已经注册，可以在命令行中使用 `list_device` 命令来查找设备，例如本例中需要使用串口 2 ，命令行查询结果如下
+
+
+
+从结果可以看出设备已经成功注册到系统中了。
+
+应用程序也可以根据设备名称来查找设备。查找设备函数如下所示：
+
+```c
+rt_device_t rt_device_find(const char* name);
+```
+
+|**参数**|**描述** |
+|----------|------------------------------------|
+| name | 设备名称 |
+|**返回**| —— |
+| 设备句柄 | 查找到对应设备将返回相应的设备句柄 |
+| RT_NULL | 没有找到相应的设备对象 |
+
+## 使用设备
+
+当需要使用的设备成功注册到系统中时，该设备就可以直接通过系统提供的接口来进行访问了。
+
+例如通用设备可以使用 `rt_device_read`、`rt_device_write` 等函数来进行数据的传输， I2C 设备可以使用 `rt_i2c_transfer` 等函数进行数据传输。更多设备相关的 API 请查看 [设备与驱动程序](https://www.rt-thread.org/document/site/programming-manual/device/device/) 中对应的设备。
+
+本例中需要使用的是串口 2，在 `application` 目录下新建 `my_uart.c` 源文件，如下图所示
+
+
+
+并在 `my_uart.c` 文件中添加如下串口设备的示例程序
+```c
+#include <rtthread.h>
+
+#define SAMPLE_UART_NAME "uart2" /* 需要操作的设备 */
+static rt_device_t serial; /* 设备句柄 */
+static char str[] = "hello RT-Thread!\r\n"; /* 需要发送的数据 */
+
+static int uart_sample(void)
+{
+ rt_err_t ret = RT_EOK;
+ rt_size_t send_len = 0;
+
+ /* 查找系统中的串口设备 */
+ serial = rt_device_find(SAMPLE_UART_NAME);
+ if (!serial)
+ {
+ rt_kprintf("find %s failed!\n", SAMPLE_UART_NAME);
+ return -RT_ERROR;
+ }
+
+ /* 以中断接收及轮询发送模式打开串口设备 */
+ ret = rt_device_open(serial, RT_DEVICE_FLAG_INT_RX);
+ if (ret != RT_EOK)
+ {
+ rt_kprintf("open device failed\r\n");
+ return -RT_ERROR;
+ }
+ /* 发送字符串 */
+ send_len = rt_device_write(serial, 0, str, (sizeof(str) - 1));
+ if (send_len != sizeof(str) - 1)
+ {
+ rt_kprintf("send data failed\r\n");
+ return -RT_ERROR;
+ }
+ /* 关闭设备 */
+ ret = rt_device_close(serial);
+ if (ret != RT_EOK)
+ {
+ rt_kprintf("close device failed\r\n");
+ return -RT_ERROR;
+ }
+
+ rt_kprintf("serial device test successful\r\n");
+
+ return RT_EOK;
+}
+/* 导出到 msh 命令列表中 */
+MSH_CMD_EXPORT(uart_sample, uart device sample);
+```
+
+编译并下载程序。在控制台中输入 `uart_sample` 命令，结果如下图
+
+
+
+使用串口工具将开发板上的串口 2 连接到电脑，可以看到开发板串口 2 收到的数据如下
+
+
+
+从上面的实验中可以看到我们成功使用系统提供的接口向串口 2 输出了数据，更多关于串口设备的使用请参看 [串口设备](https://www.rt-thread.org/document/site/programming-manual/device/uart/uart/)
+
+## 注意事项
+
+- 设备能够使用的前提是已经注册成功
+
+- nano 版没有设备的概念

+# RT-Thread Studio 结合 STM32CubeMx 开发其他驱动文档
+
+使用 `RT-Thread Studio` 新建 RT-Thread 的项目时直接就将 RT-Thread 实时操作系统移植到对应的芯片上了，省去了系统移植的步骤。
+
+使用 `STM32CubeMx` 配置工具可以方便快速的配置芯片外设的时钟和引脚，使驱动的开发变得简单。
+
+所以本文将结合这两个 IDE 的优点，介绍基于 `RT-Thread Studio` 和 `STM32CubeMx` 的驱动开发。
+
+需要注意的是这里开发的驱动是不基于 RT-Thread 设备驱动框架的，即直接使用 `STM32CubeMx` 生成的 HAL 库文件来开发外设驱动。
+
+## 简介
+
+使用 `RT-Thread Studio` 和 `STM32CubeMx` 开发驱动可分为以下几个步骤
+
+- 使用 `RT-Thread Studio` 新建 RT-Thread 工程
+
+- 使用 `STM32CubeMx` 配置外设和系统时钟
+
+- 复制 `stm32xxxx_hal_msp.c` 函数
+
+- 修改 `stm32xxxx_hal_config.h` 文件，打开相应外设支持。
+
+- 替换 `board.c ` 文件中时钟配置函数
+
+- 使用外设
+
+## 新建 RT-Thread 项目
+
+使用 `RT-Thread Studio` 新建基于 `nano-v3.1.3` 的工程，界面如下图所示
+
+
+
+配置过程可总结为以下步骤：
+
+- 定义自己的工程名及工程生成文件的存放路径
+
+- 选择 `基于芯片` 创建工程，选择的 RT-Thread 版本为 `nano-v3.1.3`。
+
+- 选择厂商及芯片型号
+
+- 配置串口信息
+
+- 配置调试器信息
+
+工程配置完成后点击下方的 `完成` 按钮即可创建 RT-Thread 的工程。
+
+基于 Studio 创建 RT-Thread 工程后，就可以基于创建的工程开发自己的驱动。下面将以 `stm32l475-atk-pandora` 开发板为例，讲解如何开发 ADC 驱动。
+
+## 配置外设
+
+新建基于目标板卡的 `CubeMx` 工程，并配置自己需要使用的外设。
+
+例如，示例开发板的 PC2 连接的是 ADC1 的通道 3，使用 `CubeMx` 生成 ADC 的驱动代码的配置结果如下所示：
+
+
+
+
+## 复制 `stm32xxxx_hal_msp.c` 函数
+
+将 `CubeMx` 生成的代码 `stm32l4xx_hal_msp.c` 函数复制到 RT-Thread Studio 生成的工程中，并参与工程编译。复制完成后的结果如下图所示
+
+
+
+由于我们并没有使用 CubeMx 生成的工程，所以这里需要将 `stm32l4xx_hal_msp.c` 文件中 `#include "main.h"` 替换为 `#include "board.h"`。
+
+## 打开 HAL 库配置文件对应外设的支持宏
+
+这里我们使用了 ADC 外设，所以需要在 `stm32l4xx_hal_config.h` 文件中将 ADC 模块使能，取消 ADC 模块的注释即可，示例代码如下
+
+```c
+#define HAL_ADC_MODULE_ENABLED
+```
+
+## 修改系统时钟(可选)
+
+使用 RT-Thread Studio 创建 RT-Thread 工程时默认使用的是系统内部时钟 HSI，这里需要根据自己的板卡配置将 `STM32CubeMx` 生成的时钟配置函数拷贝到 RT-hread 的工程中。步骤如下
+
+- 使用 CubeMx 配置自己板卡的系统时钟，并生成代码
+
+- 复制 CubeMx 工程中 `main.c` 文件的 `void SystemClock_Config(void)` 系统时钟初始化函数
+
+- 替换 `RT-Thread Studio` 生成的工程中的 `drv_clk.c` 文件中的系统时钟配置函数`void system_clock_config(int target_freq_mhz)` ，如下图所示。
+
+ 
+
+- 如果使用外部时钟，则需要更新工程中的`stm32xxxx_hal_conf.h` 中的对应的外部时钟频率的值，以 HSE 为例，需要修改下面的时钟频率为实际使用的值：
+
+ ```c
+
+ #define HSE_VALUE ((uint32_t)8000000U) /*!< Value of the External oscillator in Hz */
+
+ ```
+
+
+
+## 使用外设
+
+上述文件配置完成之后，ADC 外设就可以使用的，在 `main.c` 中添加外设的使用代码
+
+ADC 外设的使用示例代码如下
+
+```c
+#include <rtthread.h>
+#include "board.h"
+
+ADC_HandleTypeDef hadc1;
+
+/* ADC1 init function */
+void MX_ADC1_Init(void)

+
+## 注意事项
+
+- `board.c` 文件中的系统时钟配置函数需要根据自己的板卡进行修改
+
+- `stm32xxxx_hal_msp.c` 函数中主要完成的是外设引脚和时钟的初始化，所以在使用 `CubeMx` 生成外设的配置代码时不能选择为每个外设都生成 `.c/.h` 文件
+
+- 使用 `CubeMx` 外设时只需要配置实际使用的外设，如果 `stm32xxxx_hal_msp.c` 文件和 `drv_uart.c` 文件或者 `drv_spi.c` 文件外设的初始化函数重定义，需要删除 `stm32xxxx_hal_msp.c` 文件中外设的初始化函数。

+# RT-Thread Studio 驱动支持概况
+
+本文将介绍 RT-Thread Studio 对于硬件外设驱动的支持情况。由于 RT-Thread nano 版本不具有设备概念，所以本文提到的 RT-Thread 为完整版本。nano 版建议直接使用 HAL 库进行驱动开发。
+
+## 驱动概况
+
+当前 RT-Thread Studio 驱动开发方式主要分为二种
+
+- 1、由 RT Thread Studio 自动生成，无需修改任何文件或者简单定义几个宏即可直接使用的驱动，如 GPIO，UART，I2C，SPI，SDIO 和 ETH 等。
+
+- 2、没有对接到设备驱动框架，可直接使用 HAL 库函数进行开发的驱动，如 DAC，FSMC 等。
+
+RT-Thread Studio （截止V1.0.4）的驱动支持情况见下表
+
+| 外设 | Studio 自动生成 | HAL 库函数开发 |
+|------------|-----------------------|----------------|
+| PIN | 支持 | 支持 |
+| UART | 支持 | 支持 |
+| I2C | 支持 | 支持 |
+| SPI | 支持 | 支持 |
+| QSPI | 支持 | 支持 |
+| WDT | 支持 | 支持 |
+| PWM | 支持 | 支持 |
+| RTC | 支持 | 支持 |
+| FLASH | 支持 | 支持 |
+| SDIO | 支持 | 支持 |
+| USB HOST | 支持 | 支持 |
+| USB DEVICE | 支持 | 支持 |
+| ETH | 支持 | 支持 |
+| TIMER | 支持(推荐使用 HAL 库) | 支持 |
+| ADC | 支持(推荐使用 HAL 库) | 支持 |
+| DAC | 不支持 | 支持 |
+| FSMC | 不支持 | 支持 |
+| CAN | 不支持 | 支持 |
+
+## 使用简介
+
+### Studio 自动生成的驱动
+
+使用 RT-Thread Studio 新建完整版工程时，用户不需要修改任何代码，例如：
+
+- PIN ：该驱动对接到了设备驱动框架并且可以直接使用，具体 PIN 的使用参考 [PIN设备](https://www.rt-thread.org/document/site/rtthread-studio/drivers/pin/rtthread-studio-pin/)
+
+- UART ：对于串口驱动来说，生成工程的时候串口驱动也自动对接到了设备驱动框架，使用时需要自己定义串口号以及串口引脚对应的宏，具体参考 [串口设备](https://www.rt-thread.org/document/site/rtthread-studio/drivers/uart/v4.0.2/rtthread-studio-uart-v4.0.2/)
+
+- I2C ：软件 I2C 的驱动在使用 RT-Thread Studio 自动生成工程时也对接到了设备驱动框架，软件 I2C 驱动的开发参考 [软件模拟I2C设备](https://www.rt-thread.org/document/site/rtthread-studio/drivers/soft-i2c/rtthread-studio-soft-i2c/)
+
+- SPI ：SPI 设备驱动的开发参考 [SPI设备](https://www.rt-thread.org/document/site/rtthread-studio/drivers/spi/rtthread-studio-spi/)
+
+- 更多设备：更多设备驱动的开发请参考 RT-Thread 官网文档中心的相关章节。
+
+> 提示：虽然 ADC 及 Timer 外设已经对接到了设备驱动框架，但是其功能不够完善，例如：不支持 DMA，定时器的一些高级功能无法使用等。对于这类驱动，目前推荐使用 HAL 库函数方式进行开发。
+
+### 直接使用 HAL 库函数开发的驱动
+
+虽然可以通过 Studio 自动或者手动方式添加设备驱动代码，但是还是有些外设暂时无法对接到设备框架
+
+此时用户直接按照 HAL 库开发的方式，开发对应的驱动即可。具体开发方式可以参考[RT-Thread Studio 结合 STM32CubeMx 开发其他驱动文档](https://www.rt-thread.org/document/site/rtthread-studio/drivers/cubemx/rtthread-studio-cubemx/)

+# 基于 RT-Thread Studio 的 ETH 驱动开发文档
+
+## 简介
+
+`RT-Thread` 为了方便用户开发网络应用，引入了网络设备框架，同时 `RT-Thread` 还提供了数量丰富的网络组件包，方便用户快速开发自己的网络应用。
+
+本文将基于正点原子 `stm32f407-atk-explorer` 开发板主要介绍如何使用 `RT-Thread Studio` 来添加以太网驱动和 `lwIP` 协议栈。
+
+`ETH` 设备驱动的开发可总结为如下：
+
+- 新建 `RT-Thread` 完整版项目
+- `board.h`中定义 `BSP_USING_ETH` 和 `PHY` 相关的宏
+- `board.c`中初始化 `ETH` 相关的引脚和时钟
+- `stm32xxxx_hal_config.h`中打开 `HAL` 库函数对 `ETH` 的支持
+- `board.c` 中实现自己的 `PHY` 复位函数
+- 配置 `lwIP` 协议栈
+
+更多 `ETH` 的配置及添加步骤也可以参考相应工程文件 `board.h` 中对 `ETH` 部分的描述。
+
+## 新建 RT-Thread 项目
+
+使用 `RT-Thread Studio` 新建基于 `v4.0.2` 的工程，界面如下图所示：
+
+
+
+配置过程可总结为以下步骤：
+
+- 定义自己的工程名及工程生成文件的存放路径
+
+- 选择 `基于芯片` 创建工程，选择的 `RT-Thread` 版本为 `v4.0.2`
+
+- 选择厂商及芯片型号
+
+- 配置串口信息
+
+- 配置调试器信息
+
+工程配置完成后点击下方的 `Finish` 按钮即可创建 `RT-Thread` 完整版工程。
+
+## 定义 ETH 相关的宏
+
+定位到工程文件 `board.h` 中 `ETH` 配置说明部分，按照注释部分的说明分别定义 `BSP_USING_ETH` 和 `PHY` 相关的宏，本例中使用板载以太网 `PHY` 芯片为 `LAN8720A`， 所以 `ETH` 相关的宏定义如下 ：
+
+```c
+#define BSP_USING_ETH
+#ifdef BSP_USING_ETH
+#define PHY_USING_LAN8720A
+#endif
+```
+
+## 初始化引脚和时钟
+
+定义了 `BSP_USING_ETH` 宏之后，`drv_eth.c` 文件就会参与编译，该文件只是配置了 `ETH` 的工作方式和传输函数等，具体 `ETH` 外设的时钟和引脚的初始化需要借助 `STM32CubeMx` 生成的代码。
+
+将 `STM32CubeMx` 工具生成的 `ETH` 引脚和时钟初始化代码(一般在 `stm32_xxxx_hal_msp.c` 文件中)复制到自己工程的 `board.c` 文件的末尾，使之参与编译，如下所示：
+
+```c
+void HAL_ETH_MspInit(ETH_HandleTypeDef* heth)
+{
+ GPIO_InitTypeDef GPIO_InitStruct = {0};
+ if(heth->Instance==ETH)
+ {
+ /* USER CODE BEGIN ETH_MspInit 0 */
+
+ /* USER CODE END ETH_MspInit 0 */
+ /* Peripheral clock enable */
+ __HAL_RCC_ETH_CLK_ENABLE();
+
+ __HAL_RCC_GPIOC_CLK_ENABLE();
+ __HAL_RCC_GPIOA_CLK_ENABLE();
+ __HAL_RCC_GPIOG_CLK_ENABLE();
+ /**ETH GPIO Configuration
+ PC1 ------> ETH_MDC
+ PA1 ------> ETH_REF_CLK
+ PA2 ------> ETH_MDIO
+ PA7 ------> ETH_CRS_DV
+ PC4 ------> ETH_RXD0
+ PC5 ------> ETH_RXD1
+ PG11 ------> ETH_TX_EN
+ PG13 ------> ETH_TXD0
+ PG14 ------> ETH_TXD1
+ */
+ GPIO_InitStruct.Pin = GPIO_PIN_1|GPIO_PIN_4|GPIO_PIN_5;
+ GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
+ GPIO_InitStruct.Pull = GPIO_NOPULL;
+ GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
+ GPIO_InitStruct.Alternate = GPIO_AF11_ETH;
+ HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);
+
+ GPIO_InitStruct.Pin = GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_7;
+ GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
+ GPIO_InitStruct.Pull = GPIO_NOPULL;
+ GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
+ GPIO_InitStruct.Alternate = GPIO_AF11_ETH;
+ HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
+
+ GPIO_InitStruct.Pin = GPIO_PIN_11|GPIO_PIN_13|GPIO_PIN_14;
+ GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
+ GPIO_InitStruct.Pull = GPIO_NOPULL;
+ GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
+ GPIO_InitStruct.Alternate = GPIO_AF11_ETH;
+ HAL_GPIO_Init(GPIOG, &GPIO_InitStruct);
+
+ /* USER CODE BEGIN ETH_MspInit 1 */
+
+ /* USER CODE END ETH_MspInit 1 */
+ }
+
+}
+```
+
+## 打开 HAL 库对 ETH 的支持
+
+在 `stm32_xxxx_hal_config.h` 文件中打开对 `ETH` 的支持,也就是取消掉 `HAL_ETH_MODULE_ENABLED` 这个宏定义的注释，如下所示：
+
+```c
+#define HAL_ETH_MODULE_ENABLED
+```
+
+## 实现 PHY 复位函数
+
+在 `drv_eth.c` 文件中会调用 `phy_reset` 函数，该函数需要根据自己的实际情况进行实现，本例中 `PHY` 的复位引脚接在了 `PD3` 引脚，所以复位函数的实现如下所示 ：
+
+```c
+#include <rtdevice.h>
+#define RESET_IO GET_PIN(D, 3)
+
+void phy_reset(void)
+{
+ rt_pin_mode(RESET_IO, PIN_MODE_OUTPUT);
+ rt_pin_write(RESET_IO, PIN_HIGH);
+ rt_thread_mdelay(50);
+ rt_pin_write(RESET_IO, PIN_LOW);
+ rt_thread_mdelay(50);
+ rt_pin_write(RESET_IO, PIN_HIGH);
+}
+```
+
+> [!NOTE]
+> 注：不同的 `PHY` 芯片复位方式不同，需要根据具体自己板卡的实际情况进行实现。
+
+## 配置 lwIP 协议栈
+
+在前面的配置中我们已经配置好了 `ETH` 相关的硬件部分驱动,接下来就需要配置 `lwIP` 协议栈相关的内容。
+
+打开 `RT-Thread Settings` 文件，在图形化配置界面中左键单击 `lwIP` 图标即可打开 `lwIP` 协议栈的支持(组件开启，相应的图标会高亮)，如下图所示：
+
+
+
+在该选项上右键，可查看 `lwIP` 的详细配置，具体配置路径如下所示：
+```c
+RT-Thread Settings
+---- 组件
+--------网络
+------------轻量级 TCP/IP 堆栈
+```
+
+配置结果如下图所示：
+
+
+
+本例中 `lwIP` 协议栈的配置直接选择默认配置，没有做任何修改。实际使用中可以根据自己的板卡情况进行修改。
+
+## 使用网络
+
+将 `ETH` 和 `lwIP` 配置好之后编译下载程序，打开串口终端工具，在命令行中输入如下网络测试命令
+
+```c
+ping www.baidu.com
+```
+
+终端输出结果如下所示：
+
+
+
+从上图可以看出开发板已经成功连接到了网络。
+
+## 注意事项
+
+- 本例中只配置了 `lwIP` 协议栈以及 `ETH` 相关的驱动，更多关于 `RT-Thread` 网络部分的使用及介绍可以参考 [netdev 网卡](https://www.rt-thread.org/document/site/programming-manual/netdev/netdev/)，[SAL套接字抽象层](https://www.rt-thread.org/document/site/programming-manual/sal/sal/)。

+# 基于 RT-Thread Studio 的 PIN 设备应用文档
+
+## 简介
+
+一般情况下 MCU 引出供用户使用的引脚有很多个，RT-Thread 提供的 PIN 设备驱动将这些 GPIO 引脚抽象为了一个 PIN 设备，应用程序通过 PIN 设备管理接口就可以访问控制引脚。PIN 设备驱动有以下特点：
+
+- 在 PIN 驱动文件中为每个引脚重新编号，这不同于芯片手册中的编号。使用时可以通过 PIN 驱动中的引脚号操作 PIN 设备。
+- 可设置引脚输入/输出模式、可读取/设置引脚电平状态、可设置引脚中断回调函数等。
+
+使用 RT-Thread Studio 创建基于 RT-Thread 完整版的工程时，默认开启了 RT-Thread 的 PIN 设备，所以用户无须重新配置或修改源码，即可直接使用 PIN 设备。
+
+
+## 创建 RT-Thread 完整版工程
+
+使用 RT-Thread Studio 新建基于 v4.0.2 的工程，界面如下图所示
+
+
+
+配置过程可总结为以下步骤：
+
+- 定义自己的工程名及工程生成文件的存放路径
+
+- 选择`基于芯片` 创建工程，选择的 RT-Thread 版本为 v4.0.2
+
+- 选择厂商及芯片型号
+
+- 配置串口信息
+
+- 配置调试器信息
+
+工程配置完成后点击下方的`完成`按钮即可创建 RT-Thread 的工程。
+
+## 使用 PIN 设备
+
+基于 RT-Thread 完整版创建的工程中，main.c 函数里面会自动生成如下定义
+
+```c
+#define LED0_PIN GET_PIN(A, 5)
+
+int main(void)
+{
+ int count = 1;
+ /* set LED0 pin mode to output */
+ rt_pin_mode(LED0_PIN, PIN_MODE_OUTPUT);
+
+ while (count++)
+ {
+ /* set LED0 pin level to high or low */
+ rt_pin_write(LED0_PIN, count % 2);
+ LOG_D("Hello RT-Thread!");
+ rt_thread_mdelay(1000);
+ }
+
+ return RT_EOK;
+}
+```
+
+使用 PIN 驱动需要使用 `GET_PIN` 获取相应的引脚编号，获取到引脚编号后，可使用 `rt_pin_write` 等函数来操作引脚。
+例如，`stm32l475-atk-pandora` 开发板的 LED 所接的引脚为 PE7,所以修改为
+
+```c
+#define LED0_PIN GET_PIN(E, 7)
+```
+
+编译并下载代码，可以看到开发板上面的 LED 每间隔 1000 ms 闪烁一次。在终端中输入 `list_device` 命令可以看到 pin 设备已经成功注册到系统中了，如下图所示
+
+
+
+PIN 设备的更多使用说明请参考 [PIN 设备](https://www.rt-thread.org/document/site/programming-manual/device/pin/pin/)

+# 基于 RT-Thread Studio 的软件 I2C 驱动开发文档
+
+## 简介
+
+I2C 总线是 PHILIPS 公司开发的一种半双工、双向二线制同步串行总线。I2C 总线传输数据时只需两根信号线，一根是双向数据线 SDA，另一根是双向时钟线 SCL。
+
+I2C 总线可以通过芯片上板载的 I2C 外设实现，也可以通过 GPIO 引脚模拟 I2C 总线协议来实现。
+
+硬件 I2C 对应芯片上的 I2C 外设，由相应的 I2C 控制器和驱动电路组成，其所使用的引脚也是专用的。软件 I2C 使用的是普通的 GPIO 引脚，用软件控制 GPIO 管脚状态来模拟 I2C 通信波形。所以软件 I2C 不受管脚限制，接口也比较灵活。
+
+RT-Thread 的 I2C 设备驱动框架即支持硬件 I2C 也支持软件模拟 I2C。本文将基于 `stm32l475-atk-pandora` 开发板就软件 I2C 的驱动开发展开讲解。
+
+软件 I2C 的配置步骤总结如下：
+
+- 新建 RT-Thread 完整版项目
+
+- 打开软件 I2C 设备驱动框架
+
+- 定义软件 I2C 总线相关端口和引脚的宏
+
+- 使用 I2C 总线
+
+更多软件 I2C 的配置及添加步骤也可以参考相应工程文件 `board.h` 中对软件模拟 I2C 部分的描述。
+
+
+## 新建 RT-Thread 项目
+
+使用 RT-Thread Studio 新建基于 v4.0.2 的工程，界面如下图所示
+
+
+
+配置过程可总结为以下步骤：
+
+- 定义自己的工程名及工程生成文件的存放路径
+
+- 选择 `基于芯片` 创建工程，选择的 RT-Thread 版本为 v4.0.2
+
+- 选择厂商及芯片型号
+
+- 配置串口信息
+
+- 配置调试器信息
+
+工程配置完成后点击下方的 `完成` 按钮即可创建 RT-Thread 的工程。
+
+## 打开 I2C 设备驱动框架
+
+在 `RT-Thread Setting` 文件中借助图形化配置工具打开软件 I2C 的驱动框架，如下图所示
+
+
+
+左键单击即可开启 `软件模拟 I2C`(组件开启，相应的图标会高亮)，在该选项上右键，可以查看软件模拟 I2C 的 `详细配置`，具体配置如下所示
+
+```c
+RT-Thread Setting
+----组件
+--------设备驱动程序
+------------使用 I2C 设备驱动程序
+----------------使用 GPIO 模拟 I2C
+```
+
+配置结果如下图所示
+
+
+
+## 定义软件 I2C 相关的宏
+
+在 board.h 文件中定义软件 I2C 相关的宏
+
+```c
+#define BSP_USING_I2C1 /* 使用 I2C1 总线 */
+#define BSP_I2C1_SCL_PIN GET_PIN(C, 1) /* SCL -> PC1 */
+#define BSP_I2C1_SDA_PIN GET_PIN(D, 6) /* SDA -> PD6 */
+```
+
+上述 I2C 总线相关的宏表示 I2C1 总线的 SCL 时钟线连接在 PC1 引脚，SDA 数据线连接在 PD6 引脚。如果需要使用多个 I2C 总线，相关的宏定义参考 board.h 文件中 I2C1 的宏进行定义即可
+
+## I2C 总线的使用
+
+编译并下载程序在终端中输入 `list_device` 测试命令可以看到 i2c1 已经成功注册到系统中了，如下图所示
+
+
+
+更多 I2C 总线的应用请参考 [I2C 总线设备应用示例](https://www.rt-thread.org/document/site/programming-manual/device/i2c/i2c/#i2c_4)
+
+
+## 注意事项
+
+- STM32 软件 I2C 的驱动依赖于 PIN 设备驱动。

+# 基于 RT-Thread Studio 的 SPI 驱动开发文档
+
+## 简介
+
+SPI 是一种高速、全双工、同步串行通信总线，常用于 MCU 与数字芯片之间的短距离通讯。RT-Thread 的 SFUD 组件，RW007 WIFI 模块均使用到了 SPI 驱动。下面将基于 `stm32l475-atk-pandora` 开发板，讲解基于 RT-Thread Studio 开发 SPI 驱动。
+
+SPI 设备驱动的开发可总结为如下：
+
+- 新建 RT-Thread 完整版项目
+
+- 打开 SPI 设备驱动框架
+
+- 定义 SPI 总线相关的宏
+
+- 打开 HAL 库函数对 SPI 总线的支持
+
+- 复制 SPI 引脚初始化函数到工程
+
+更多 SPI 总线的配置及添加步骤也可以参考相应工程文件 `board.h` 中对 SPI 总线部分的描述。
+
+## 新建 RT-Thread 项目
+
+使用 RT-Thread Studio 新建基于 v4.0.2 的工程，界面如下图所示
+
+
+
+配置过程可总结为以下步骤：
+
+- 定义自己的工程名及工程生成文件的存放路径
+
+- 选择 `基于芯片` 创建工程，选择的 RT-Thread 版本为 v4.0.2
+
+- 选择厂商及芯片型号
+
+- 配置串口信息
+
+- 配置调试器信息
+
+工程配置完成后点击下方的 `完成` 按钮即可创建 RT-Thread 的工程。
+
+## 打开 SPI 设备驱动框架
+
+在 `RT-Thread Setting` 文件中借助图形化配置工具打开软件 SPI 的驱动框架，如下图所示
+
+
+
+左键单击即可开启 `SPI` 驱动框架(组件开启，相应的图标会高亮)，在该选项上右键，可查看 SPI 的 `详细配置`，具体配置路径如下所示
+
+```c
+RT-Thread Setting
+----组件
+--------设备驱动程序
+------------使用 SPI 总线/设备驱动程序
+```
+
+配置结果如下图所示
+
+
+
+## 定义 SPI 总线相关的宏
+
+在 board.h 文件中定义 SPI 总线相关的宏，本例中使用 SPI3 总线，只需定义如下宏即可
+
+```c
+#define BSP_USING_SPI3
+```
+
+## 打开 HAL 库对 SPI 的支持
+
+在 stm32xxxx_hal_config.h 文件中打开对 SPI 的支持,也就是取消掉 HAL_SPI_MODULE_ENABLED 这个宏定义的注释，如下所示：
+```c
+#define HAL_SPI_MODULE_ENABLED
+```
+
+## 初始化引脚和时钟
+
+定义了 `BSP_USING_SPI3` 宏之后，`drv_spi.c` 文件就会参与编译，该文件只是配置了 SPI 的工作方式和传输函数，具体 SPI 外设的时钟和引脚的初始化需要借助 `STM32CubeMx` 生成的代码。
+
+例如 `stm32l475-atk-pandora` 开发板的 `SPI3` 外设连接了一个 `LCD` 屏幕，所以需要将 CubeMx 生成的 `SPI3` 的初始化代码(一般在 `stm32_xxxx_hal_msp.c` 文件中)复制到自己工程的 `board.c` 文件的末尾，使之参与编译，如下所示
+
+```c
+void HAL_SPI_MspInit(SPI_HandleTypeDef* hspi)
+{
+ GPIO_InitTypeDef GPIO_InitStruct = {0};
+ if(hspi->Instance == SPI3)
+ {
+ /* USER CODE BEGIN SPI3_MspInit 0 */
+
+ /* USER CODE END SPI3_MspInit 0 */
+ /* Peripheral clock enable */
+ __HAL_RCC_SPI3_CLK_ENABLE();
+
+ __HAL_RCC_GPIOC_CLK_ENABLE();
+ __HAL_RCC_GPIOB_CLK_ENABLE();
+ /**SPI3 GPIO Configuration
+ PC11 ------> SPI3_MISO
+ PB3 (JTDO-TRACESWO) ------> SPI3_SCK
+ PB5 ------> SPI3_MOSI
+ */
+ GPIO_InitStruct.Pin = GPIO_PIN_11;
+ GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
+ GPIO_InitStruct.Pull = GPIO_NOPULL;
+ GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
+ GPIO_InitStruct.Alternate = GPIO_AF6_SPI3;
+ HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);
+
+ GPIO_InitStruct.Pin = GPIO_PIN_3 | GPIO_PIN_5;
+ GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
+ GPIO_InitStruct.Pull = GPIO_NOPULL;
+ GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
+ GPIO_InitStruct.Alternate = GPIO_AF6_SPI3;
+ HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);
+
+ /* USER CODE BEGIN SPI3_MspInit 1 */
+
+ /* USER CODE END SPI3_MspInit 1 */
+ }
+}
+```
+
+如果需要注册更多的 SPI 总线设备，只需参考 `board.h` 文件中 SPI 相关的宏定义并拷贝引脚初始化函数即可。
+
+## SPI 总线的使用
+
+编译并下载程序输入 `list_device` 测试命令可以看到 SPI 总线设备已经成功注册到系统中了，如下图所示
+
+
+
+> 提示：这里只是注册了一个 SPI 总线设备，SPI 从设备的挂载请参考 [挂载 SPI 从设备](https://www.rt-thread.org/document/site/programming-manual/device/spi/spi/#spi_2)

+# 基于 RT-Thread Studio 的串口驱动开发文档
+
+## 简介
+
+使用 RT-Thread Studio 新建基于 RT-Thread 的项目时，串口驱动已经自动添加到工程中，不需要用户手动添加和串口驱动相关的源码，用户可以很方便的使用串口进行输入输出。同时，基于 Studio 的图形化配置界面，更改串口的配置也更加简洁，用户不需要更改和驱动相关的源代码，只需要更改或新增相关的宏即可，下面将基于 `stm32l475-atk-pandora` 开发板就 RT-Thread 的 nano 版和完整版分别展开讲解。完整版串口驱动开发文档参见 [完整版串口驱动开发](../v4.0.2/rtthread-studio-uart-v4.0.2.md)。
+
+## RT-Thread nano 版串口的驱动开发
+
+nano 版串口驱动的使用主要用于控制台的输入与输出。
+
+### 配置默认串口
+
+使用 RT-Thread Studio 新建基于 nano 的工程，界面如下图所示
+
+
+
+配置过程可总结为以下步骤：
+
+- 定义自己的工程名及工程生成文件的存放路径
+
+- 选择 `基于芯片` 创建工程，并选择 RT-Thread 的版本为 nano 版
+
+- 选择厂商及芯片型号
+
+- 配置串口信息
+
+- 配置调试器信息
+
+工程配置完成后点击下方的`完成`按钮即可创建 RT-Thread 的工程。在 RT-Thread 工程的 main.c 文件中会自动生成如下代码:
+
+```c
+int main(void)
+{
+ int count = 1;
+
+ while (count++)
+ {
+ LOG_D("Hello RT-Thread!");
+ rt_thread_mdelay(1000);
+ }
+
+ return RT_EOK;
+}
+```
+
+编译并下载工程后，打开串口 Studio 自带的串口工具即可看到串口输出的打印信息，如下所示
+
+
+
+从串口输出的信息中可以看到我们已经成功使用串口输出了打印信息。
+
+
+### 修改默认串口
+
+上节中基于 Studio 的图形化界面成功配置了串口的输出，但是一些实际的应用的可能需要使用其他串口输出信息，这种情况则可以通过修改一些宏定义实现。
+
+#### 修改 `board.h` 宏
+
+演示所用的开发板 `stm32l475-atk-pandora` 默认使用 UART1 进行输出，若要改为 UART2(`TX->PA2`、`RX->PA3`)进行输出，，则将 `board.h` 中串口 1 的 5 个宏
+
+```c
+#define BSP_USING_UART1
+#define BSP_UART1_TX_PIN "PA9"
+#define BSP_UART1_RX_PIN "PA10"
+```
+
+修改为串口 2 的以下宏
+```c
+#define BSP_USING_UART2
+#define BSP_UART2_TX_PIN "PA2"
+#define BSP_UART2_RX_PIN "PA3"
+```
+
+宏定义的修改主要分为三个方面
+
+- 修改串口对应的宏定义，如 `BSP_USING_UART1`、`BSP_USING_UART2`等。
+
+- 修改串口 `TX/RX` 所使用的端口，如 `"PA2"`、`"PA3"`等。
+
+
+#### 使用更改后的串口输出
+
+board.h 中的宏修改完成之后，编译、下载。使用 USB 转串口线连接好 PA2、和 PA3 的引脚，并打开 Studio 中自带的串口工具，串口输出的 log 如下所示
+
+
+
+从输出的信息可以看出控制台切换到串口 2 后成功进行了输出。
+
+## 常见问题
+
+### Q：如何给 Nano 添加 Finsh？
+
+A： 参考 [基于 Nano 添加 Finsh 章节](https://www.rt-thread.org/document/site/tutorial/nano/nano-port-studio/an0047-nano-port-studio/#nano-finsh)。

+使用 RT-Thread Studio 新建基于 v4.0.2 的工程，界面如下图所示
+
+
+
+配置过程可总结为以下步骤：
+
+- 定义自己的工程名及工程生成文件的存放路径
+
+- 选择`基于芯片` 创建工程，选择的 RT-Thread 版本为 v4.0.2
+
+- 选择厂商及芯片型号
+
+- 配置串口信息
+
+- 配置调试器信息
+
+工程配置完成后点击下方的`完成`按钮即可创建 RT-Thread 的工程。在 RT-Thread 工程的 main.c 文件中会自动生成如下代码:
+
+```c
+/* PLEASE DEFINE the LED0 pin for your board, such as: PA5 */
+#define LED0_PIN GET_PIN(A, 5)
+
+int main(void)
+{
+ int count = 1;
+ /* set LED0 pin mode to output */
+ rt_pin_mode(LED0_PIN, PIN_MODE_OUTPUT);
+
+ while (count++)
+ {
+ /* set LED0 pin level to high or low */
+ rt_pin_write(LED0_PIN, count % 2);
+ LOG_D("Hello RT-Thread!");
+ rt_thread_mdelay(1000);
+ }
+
+ return RT_EOK;
+}
+```
+
+代码中会每间隔 1000 ms 在控制台中打印 `Hello RT-Thread!` 。编译并下载工程后，打开串口 Studio 自带的串口工具即可看到串口输出的打印信息，如下所示
+
+
+
+从串口输出的信息中可以看到我们已经成功使用串口输出了打印信息。
+
+在控制台中输入 `list_device` 可以看到 `uart1` 设备已经成功注册到系统中，如下图所示
+
+
+
+### 修改默认串口
+
+上节中基于 Studio 的图形化界面成功配置了串口的输出，但是一些实际的应用的可能需要使用其他串口输出信息，这种情况则可以通过修改一些宏定义及 RT-Thread Setting 文件来实现。
+
+#### 修改 `board.h` 宏
+
+演示所用的开发板 `stm32l475-atk-pandora` 默认使用 UART1 进行输出，若要修改为串口 2 (`TX->PA2`、`RX->PA3`)进行输出，则在 board.h 中定义宏 `BSP_USING_UART2`，并将串口 2 对应的引脚信息修改为实际所使用的引脚，如下所示
+
+
+
+宏定义的修改主要分为三个方面
+
+- 修改串口对应的宏定义，如 `BSP_USING_UART1`、`BSP_USING_UART2`等。
+
+- 修改串口 `TX/RX` 所使用的端口，如 `"PA2"`、`"PA3"`等。
+
+
+
+#### 修改 `RT-Thread Setting` 文件
+
+在 RT-Thread Setting 文件中修改输出控制台的串口设备名称，修改路径如下：
+```c
+RT-Thread Setting
+----内核
+--------RT-Thread 内核
+------------内核设备对象
+----------------为 rt_kprintf 使用控制台
+--------------------控制设备台的名称
+```
+
+配置如下图所示
+
+
+
+保存工程配置并编译、下载，串口输出如下图所示
+
+
+
+输入 `list_device` 命令可查看已注册的设备，如下图所示
+
+
+
+从终端打印的信息可以看到控制台的串口设备已经成功的从串口 1 更换到了串口 2。
+
+### 新增串口
+
+新增串口只需要在 `board.h` 文件中定义相关串口的宏定义 `BSP_USING_UARTx` 及修改引脚信息即可
+
+新增串口的步骤总结如下
+
+- 新增对应串口的宏定义，如 BSP_USING_UART1、BSP_USING_UART2等。
+
+- 修改串口 `TX/RX` 所使用的端口，如 `"PA9"`、`"PA10"`等。
+
+
+基于修改控制台章节新增串口 1 的示例如下
+
+
+
+编译并下载程序，在控制台输入 `list_device` 命令可以看到已经注册了两个串口设备，串口 1 和串口 2。如下图所示
+
+
+
+从控制台输出的信息可以看到两个串口设备均已注册到系统中了。
+
+
+### 串口 DMA 的使用
+
+#### RT-Thread Setting 配置 DMA
+
+如果要使用串口 DMA 的功能，需要使用 RT-Thread Setting 打开 DMA 的支持。配置路径为
+
+```c
+RT-Thread Setting
+----组件
+--------设备驱动程序
+------------使用 UART 设备驱动程序
+----------------使能串口 DMA 模式。
+```
+
+配置过程如下图所示
+
+
+
+#### 配置 `board.h` 中的宏
+
+如果需要使用串口 DMA 只需要在 `board.h` 文件中定义如下宏即可
+
+```c
+#define BSP_UARTx_RX_USING_DMA
+#define BSP_UARTx_TX_USING_DMA
+```
+
+- `UARTx` 表示的是哪个串口需要使用 DMA，使用的是 DMA 的发送还是接收功能。此例中使用的是串口 2 的 DMA 接收功能，所以定义了宏 `BSP_UART2_RX_USING_DMA`，串口 2 使用 DMA 的配置如下所示
+
+
+
+将 [DMA 接收及轮询发送](https://www.rt-thread.org/document/site/programming-manual/device/uart/uart/#dma) 章节中的DMA 的测试代码添加到工程中
+
+编译并下载程序，在控制台中输入 `uart_dma_sample` 命令，并使用 USB 转串口线连接串口 2，在串口 2 中可以看到如下打印信息
+
+
+
+测试程序已经成功使用 DMA 进行了接收。
+
+更多关于串口的使用请查看 [UART设备](https://www.rt-thread.org/document/site/programming-manual/device/uart/uart/)

+# 基于 RT-Thread Studio 的 USB Device 驱动开发文档
+
+
+## 简介
+
+`USB` 即 `Universal Serial Bus` 是一种支持热插拔的通用串行总线，在 `USB` 体系中又分为 `USB Host` 和 `USB Device`。本文将基于 `stm32l475-atk-pandora` 开发板，讲解基于 `RT-Thread Studio` 开发 `USB Device` 驱动。
+
+`USB Device` 设备驱动的开发可总结为如下几个步骤：
+
+- 新建 `RT-Thread` 完整版项目
+
+- 打开 `USB Device` 设备驱动框架，并配置相关的子类
+
+- `board.h`中定义 `USB Device` 相关的宏
+
+- `board.c` 中初始化 `USB Device` 的引脚及外设时钟
+
+- `stm32xxxx_hal_config.h` 中打开 `HAL` 库函数对 `USB Device` 的支持
+
+
+
+更多关于`USB Device` 的配置及添加步骤也可以参考相应工程文件 `board.h` 中对 `USB Device` 部分的描述。
+
+## 新建 RT-Thread 项目
+
+使用 `RT-Thread Studio` 新建基于 `v4.0.2` 的工程，界面如下图所示：
+
+
+
+配置过程可总结为以下步骤：
+
+- 定义自己的工程名及工程生成文件的存放路径
+
+- 选择 `基于芯片` 创建工程，选择的 `RT-Thread` 版本为 `v4.0.2`
+
+- 选择厂商及芯片型号
+
+- 配置串口信息
+
+- 配置调试器信息
+
+工程配置完成后点击下方的 `Finish` 按钮即可创建 `RT-Thread` 的工程。
+
+## 打开 USB Device 设备驱动框架
+
+在 `RT-Thread Settings` 文件中配置 `USB Device` ，配置路径如下：
+
+```c
+组件
+---- 设备驱动程序
+--------使用 USB
+------------使用 USB 设备
+----------------选择设备类型
+```
+
+本例中将 `USB Device` 配置为一个 `CDC` 的子类—虚拟串口，配置图如下所示：
+
+
+
+虚拟串口的属性等信息这里选择默认并未做任何修改，实际使用过程中按照需要修改即可。
+
+## 定义 USB Device 宏
+
+定位到工程文件 `board.h` 中关于 `USB Device` 的配置说明部分，按照注释部分的说明定义 `BSP_USING_USBDEVICE` 的宏，如下所示：
+
+```c
+#define BSP_USING_USBDEVICE
+```
+
+## 初始化引脚和时钟
+
+定义了 `BSP_USING_USBDEVICE` 宏之后，`drv_usbd.c` 文件就会参与编译，该文件只是配置了 `USB Device` 的工作方式和传输函数等，具体 `USB Device` 引脚和时钟的初始化需要借助 `STM32CubeMx` 生成的代码。
+
+将 `STM32CubeMx` 工具生成的 `USB Device` 引脚和时钟初始化代码(一般在 `stm32_xxxx_hal_msp.c` 文件中)复制到自己工程的 `board.c` 文件的末尾，使之参与编译，如下所示：
+
+```c
+void HAL_PCD_MspInit(PCD_HandleTypeDef* hpcd)
+{
+ GPIO_InitTypeDef GPIO_InitStruct = {0};
+ if(hpcd->Instance==USB_OTG_FS)
+ {
+ /* USER CODE BEGIN USB_OTG_FS_MspInit 0 */
+
+ /* USER CODE END USB_OTG_FS_MspInit 0 */
+
+ __HAL_RCC_GPIOA_CLK_ENABLE();
+ /**USB_OTG_FS GPIO Configuration
+ PA11 ------> USB_OTG_FS_DM
+ PA12 ------> USB_OTG_FS_DP
+ */
+ GPIO_InitStruct.Pin = GPIO_PIN_11|GPIO_PIN_12;
+ GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
+ GPIO_InitStruct.Pull = GPIO_NOPULL;
+ GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
+ GPIO_InitStruct.Alternate = GPIO_AF10_OTG_FS;
+ HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
+
+ /* Peripheral clock enable */
+ __HAL_RCC_USB_OTG_FS_CLK_ENABLE();
+
+ /* Enable VDDUSB */
+ if(__HAL_RCC_PWR_IS_CLK_DISABLED())
+ {
+ __HAL_RCC_PWR_CLK_ENABLE();
+ HAL_PWREx_EnableVddUSB();
+ __HAL_RCC_PWR_CLK_DISABLE();
+ }
+ else
+ {
+ HAL_PWREx_EnableVddUSB();
+ }
+ /* USB_OTG_FS interrupt Init */
+ HAL_NVIC_SetPriority(OTG_FS_IRQn, 0, 0);
+ HAL_NVIC_EnableIRQ(OTG_FS_IRQn);
+ /* USER CODE BEGIN USB_OTG_FS_MspInit 1 */
+
+ /* USER CODE END USB_OTG_FS_MspInit 1 */
+ }
+}
+```
+
+## 配置 USB 外设时钟
+
+使用 `RT-Thread Studio` 自动生成工程的时候，在 `board.c` 文件中的系统时钟初始化函数 `SystemClock_Config` 中，有些外设的时钟是默认没有开启的。当需要使用这些外设的时候，同样需要借助 `STM32CubeMX` 工具生成的代码来初始化外设时钟。
+
+本例中需要使用到 `USB` 这个外设，使用 `STM32CubeMX` 工具配置好系统时钟以后将工程 `board.c` 文件中的 `SystemClock_Config` 函数替换为自己使用 `STM32CubeMX` 工具生成的函数，如下所示：
+
+```c
+void SystemClock_Config(void)
+{
+ RCC_OscInitTypeDef RCC_OscInitStruct = {0};
+ RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};
+ RCC_PeriphCLKInitTypeDef PeriphClkInit = {0};
+
+ /** Configure LSE Drive Capability
+ */
+ HAL_PWR_EnableBkUpAccess();
+ __HAL_RCC_LSEDRIVE_CONFIG(RCC_LSEDRIVE_LOW);
+ /** Initializes the CPU, AHB and APB busses clocks
+ */
+ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_LSI|RCC_OSCILLATORTYPE_HSE
+ |RCC_OSCILLATORTYPE_LSE;
+ RCC_OscInitStruct.HSEState = RCC_HSE_ON;
+ RCC_OscInitStruct.LSEState = RCC_LSE_ON;
+ RCC_OscInitStruct.LSIState = RCC_LSI_ON;
+ RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
+ RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE;
+ RCC_OscInitStruct.PLL.PLLM = 1;
+ RCC_OscInitStruct.PLL.PLLN = 20;
+ RCC_OscInitStruct.PLL.PLLP = RCC_PLLP_DIV7;
+ RCC_OscInitStruct.PLL.PLLQ = RCC_PLLQ_DIV2;
+ RCC_OscInitStruct.PLL.PLLR = RCC_PLLR_DIV2;
+ if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
+ {
+ Error_Handler();
+ }
+ /** Initializes the CPU, AHB and APB busses clocks
+ */
+ RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK
+ |RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2;
+ RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_PLLCLK;
+ RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
+ RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV1;
+ RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;
+
+ if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_4) != HAL_OK)
+ {
+ Error_Handler();
+ }
+ PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_RTC|RCC_PERIPHCLK_USART1
+ |RCC_PERIPHCLK_USART2|RCC_PERIPHCLK_USB
+ |RCC_PERIPHCLK_ADC;
+ PeriphClkInit.Usart1ClockSelection = RCC_USART1CLKSOURCE_PCLK2;
+ PeriphClkInit.Usart2ClockSelection = RCC_USART2CLKSOURCE_PCLK1;
+ PeriphClkInit.AdcClockSelection = RCC_ADCCLKSOURCE_PLLSAI1;
+ PeriphClkInit.RTCClockSelection = RCC_RTCCLKSOURCE_LSE;
+ PeriphClkInit.UsbClockSelection = RCC_USBCLKSOURCE_PLLSAI1;
+ PeriphClkInit.PLLSAI1.PLLSAI1Source = RCC_PLLSOURCE_HSE;
+ PeriphClkInit.PLLSAI1.PLLSAI1M = 1;
+ PeriphClkInit.PLLSAI1.PLLSAI1N = 12;
+ PeriphClkInit.PLLSAI1.PLLSAI1P = RCC_PLLP_DIV7;
+ PeriphClkInit.PLLSAI1.PLLSAI1Q = RCC_PLLQ_DIV2;
+ PeriphClkInit.PLLSAI1.PLLSAI1R = RCC_PLLR_DIV2;
+ PeriphClkInit.PLLSAI1.PLLSAI1ClockOut = RCC_PLLSAI1_48M2CLK|RCC_PLLSAI1_ADC1CLK;
+ if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit) != HAL_OK)
+ {
+ Error_Handler();
+ }
+ /** Configure the main internal regulator output voltage
+ */
+ if (HAL_PWREx_ControlVoltageScaling(PWR_REGULATOR_VOLTAGE_SCALE1) != HAL_OK)
+ {
+ Error_Handler();
+ }
+}
+```
+
+## 打开 HAL 库对 USB Device 的支持
+
+在 `stm32_xxxx_hal_config.h` 文件中打开对 `USB Device` 的支持，也就是取消掉 `HAL_PCD_MODULE_ENABLED` 这个宏定义的注释，如下所示：
+```c
+#define HAL_PCD_MODULE_ENABLED
+```
+
+## 使用
+
+上述步骤配置完成以后，编译下载程序，在终端中输入 `list_device` 命令，结果如下：
+
+
+
+从终端中输出的结果可以看到 `USB Device` 设备和虚拟串口设备已经成功注册到系统中了。
+
+在 `Windows` 上打开设备管理器，并将开发板上的 `USB Device` 接口通过数据线连接到电脑，在电脑的设备管理器中可以看到下图：
+
+
+
+从上图可以看到电脑已经成功的枚举了上面配置的虚拟串口设备。

+# 常见问题
+
+
+
+## 如何添加文件到工程
+
+可以直接通过复制粘贴往RT-Thread Studio工程里添加文件，甚至可以直接可以往工程里复制粘贴整个文件夹，也可以通过右键新建向导选择新建文件夹，新建C源码文件或H头文件，如果添加文件后构建提示文件找不到，请到工程构建配置里将添加的文件添加Include包含头文件路径
+
+## 如何让源码显示行号
+
+在源码编辑窗口的左边栏上右键，选择`显示行号`，即可显示行号，如下图所示：
+
+
+
+## 导入项目的入口在哪里
+
+通过`项目资源管理器`窗口右键`导入`菜单打开导入向导窗口，选择 `现有项目到工作空间中`，如下图所示：
+
+
+
+点击`下一步`后，通过`浏览`按钮，选择要导入的项目所在目录，向导会自动扫描目录下所有可导入的工程并列在项目列表中，勾选要导入的工程，然后点击`完成`即可完成导入工程，如下图所示:
+
+
+
+## 如何生成 HEX 文件
+
+选中工程后，点击工具栏上的`打开构建配置`按钮，将相应的输出文件格式设置成 hex 文件格式，即可实现输出 hex 文件，如下图所示：
+
+
+
+如果需要同时生成 bin 文件和 hex 文件，需要在`构建后步骤`里添加构建后生成 HEX 文件的命令，如下图所示：
+
+
+
+构建后生成的 hex 文件，在工程的`Debug`目录下，如下图所示：
+
+
+
+## 串口出现丢失字符怎么办
+
+排除程序的原因外，串口线的质量，波特率是否设置过高都是需要考虑的因素，可以尝试换个串口线，或者将波特率调低点试试。
+
+## 删除工程的时候删不掉怎么办
+
+由于工程里可能有 git 文件被 git 程序占用造成工程有时删除部分后失败，提示占用问题，可以试试删除工程先前先关闭工程，等待一会后再删除，或者删除失败后，通过重启菜单重启一下 RT-Thread Studio 就可以正常删除了，重新启动菜单入口（菜单栏文件菜单内）和关闭项目（项目上右键菜单内）入口如下图所示：
+
+
+
+## 用户是否可以修改 rt-thread 及 packages 目录下的文件及配置
+
+不可以。rt-thread 及 packages 目录下的文件统一使用 RT-Thread Setting 文件来管理和配置，当需要这两个目录下的相关文件参与编译时，应该在 RT-Thread Setting 文件中来打开相关功能。
+
+例如用户想让当前 rt-thread 目录下的 dfs 参与编译，如下图所示
+
+
+
+用户不能直接修改文件属性让 dfs 文件参与编译，而是通过 RT-Thread Setting 文件打开 DFS 的配置，保存配置后 dfs 的配置后，Studio 会自动将 dfs 文件添加到构建文件中，如下图所示
+
+
+
+## Studio 编译结果中 text，data，bss，dec 和 hex 的各个含义是什么
+
+Studio 的编译结果如下图所示
+
+
+
+- text：代码段，用来存放代码及一些只读常量，一般是只读的区域
+
+- data：数据段，用来存放全局初始化变量，以及全局或局部静态变量
+
+- bss：BSS 段，用来存放所有未初始化的数据，用 0 来初始化
+
+- dec：是 decimal 即十进制的缩写，是 text，data 和 bss 的算术和
+本例中:51344 + 372 + 2808 = 54524
+
+- hex：是 hexadecimal 即十六进制的缩写，本例中：十进制数 54524 对应的十六进制就是 d4fc
+
+- filename：编译生成的目标文件名，本例中即为：rtthread.elf
+
+编译生成的目标文件占用内存的计算方法
+
+程序占用的 FLASH 大小 = text 段的大小 + data 段的大小
+
+程序占用的 RAM 大小 = data 段的大小 + bss 段的大小
+
+## ST-LINK烧写端口被占用怎么办
+
+ 当弹出错误对话框提示“TCP Port 61234 not available”时, 打开调试配置修改 ST-LINK端口号即可, 如下图所示：
+
+
+
+## 打开RT-thread settings窗口，为什么看不到图标界面
+
+新建工程选择RT-Thread非Nano版本源码即可, Nano是纯净版，没有组件概念
+
+## RT-Thread Studio 升级失败
+
+总共分两种情况：
+
+- 如果更新失败提示信息里有 “org.eclipse.equinox.internal.p2.engine.phases.CheckTrust”
+RT-Thread Studio 升级前请先关闭翻墙工具，或尝试删除安装目录下的“artifacts.xml”文件重启再试
+
+- 如果更新失败提示信息里有 “No Repository found”或发生下图所示错误，请手动探测更新。在更新页面内，取消勾选 “Group items by category”和“Contact all update sites during install to find required software” 并勾选"Eclipse Platform Launcher Executables",然后尝试安装studio更新，若安装过程中出错，关闭后重试一次即可 。
+
+ 
+
+ 
+
+ 
+
+## 如何启用黑色主题和设置编辑器配色
+
+通过`首选项`的`外观`配置项选择“DevStyle Theme”即可启用新的黑色主题，切换主题后需要重启Studio后才会生效
+
+
+
+
+
+## 如何查看和修改快捷键
+
+通过`帮助`菜单打开`键辅助`可查看快捷键
+
+
+
+
+
+## 如何恢复界面
+
+
+
+## 如何打开关闭的项目
+右键菜单，`打开项目`即可，如下图所示：
+
+
+
+## 创建工程失败 装载 python DLL 出错 怎么办
+
+- 问题描述： Error loading Python DLL `xxx/MEI85262/python36.dll`. LoadLibrary:找不到指定程序
+
+
+
+- 解决方法：请手动安装 Visual C++ Redistributable, [点我下载](https://realthread.cowtransfer.com/s/96d5e5928fc54e)
+
+## 如何取消启动调试前的自动构建
+
+首先通过`窗口`菜单打开`首选项`窗口，然后展开`运行/调试`选项并点击进入`启动`选项，最后将`在启动之前构建（如必需）`选项取消勾选即可取消启动调试前的自动构建，如下图所示：
+
+
+
+## 项目资源管理器如何 显示/隐藏 被排除构建的资源
+
+RT-Thread Studio 从 V 1.1.4 版本开始支持`显示/隐藏`被排除构建的资源，如下图所示，这些被排除构建的资源显示为灰色，并且资源图标上有斜杠标志，被排除构建的资源将不会在启动编译时参与编译，Studio 默认隐藏了这些资源。
+
+
+
+- 如果想`显示/隐藏`这些资源，请先点击项目资源管理器右上角的倒三角，会展示如下菜单，点击过滤器和定制：
+
+
+
+- 在过滤器和定制中，有很多可以选择过滤的资源，`勾选/取消勾选` RTT Excluded Resource ，即可`隐藏/显示`被排除构建的资源。
+
+
+
+## 如何解决 studio 编译链接时命令行超出 windows 长度限制的问题
+
+编译工程链接的时候，若出现如下图所示【 CreateProcess : No such file or directory 】的错误，可能是因为工程文件过多或者目录名过长等原因导致链接时命令行过长，部分 .o 被截断产生的问题。
+
+
+
+Windows 下命令行的字符串长度限制为 8191 个字符，当然我们也有办法去解决此限制，请使用以下一种或者多种方法来解决这个问题（根据您的具体情况）：
+
+ - 缩短链接文件的路径
+ - 为文件夹和文件使用较短的名称
+ - 减少文件夹树的深度
+ - 将文件存储在更少的文件夹中
+
+ - 修改工程链接配置命令**（推荐）**
+ - 在 C/C++ Build/Settings/Gnu ARM Cross C++ Linker 中配置 Command line pattern 为
+
+ ```
+ @$(file >link.temp,${cross_toolchain_flags} ${FLAGS} ${OUTPUT_FLAG} ${OUTPUT_PREFIX}${OUTPUT} ${INPUTS}) ../project_linker.exe link.temp ${COMMAND}
+ ```
+
+ 
+ - 在工程目录下添加 project_link.exe 可执行文件，可在此下载 [project_linker.exe](../figures/project_linker.exe)
+
+ 
+
+ - 重新编译工程，即可正常进行链接
+
+## 如何解决 studio 清理工程时命令行超出 windows 限制的问题
+
+在清理 ( Clean ) 工程的时候，当工程过大时，可能会和链接时一样出现 process_begin : CreateProcess 的问题，由于命令 rm 后的参数过长，导致 windows 不能处理此命令。
+
+
+
+推荐您使用以下方法解决这个问题：
+
+- 点击下载 [clean_script.exe](../figures/clean_script.exe)
+
+- 将 clean_script.exe 置于工程根目录下
+
+- 修改工程根目录下的 makefile.targets 中的 clean2 命令为 :
+
+ ```
+ clean2:
+ @$(file > clean, $(OBJS) $(C_DEPS) $(CPP_DEPS))../clean_script.exe clean
+ -$(RM) $(CC_DEPS) $(C++_DEPS) $(C_UPPER_DEPS) $(CXX_DEPS) $(SECONDARY_FLASH) $(SECONDARY_SIZE) $(ASM_DEPS) $(S_UPPER_DEPS) *.elf
+ -@echo ' '
+ ```
+
+ 注：clean2 下的命令前的空格是 Tab ，不能使用空格键
+
+- 重新清理工程
+
+## 添加软件包后在 packages 目录找不到的解决办法
+
+如果在 RT-Thread Settings 添加软件包后，在 packages 目录下找不到软件包或者软件包被排除编译，请尝试以下方法：
+
+- 以 network_samples-v0.3.0 软件包为例：
+
+ - 双击打开 RT-Thread Settings
+
+ 
+
+ - 右键不能显示的软件包，打开详细配置
+
+ 
+
+ - 为该软件包配置至少配置一个子选项，不然和没勾选的参与编译情况是一样的
+
+ 
+
+ - 保存该配置即可
+
+

+## 界面介绍
+
+### 界面简介
+
+RT-Thread Studio 基于 eclipse 平台开发，界面设计和风格继承自 eclipse，RT-Thread Studio 启动后主界面结构如下图所示：
+
+
+
+### 透视图简介
+
+透视图定义了当前界面呈现的菜单栏，工具栏，以及功能窗口集合及其布局。不同透视图提供了完成特定类型任务的功能集合。例如 C 透视图组合了项目开发，源文件编辑，项目构建等常用的开发功能窗口，菜单和功能按钮，调试透视图包含了调试项目程序常用的调试功能窗口，菜单和功能按钮。
+
+RT-Thread Studio 已实现启动调试时自动切换到调试透视图，停止调试时自动恢复到 C 透视图，用户平时也可以根据需要从 ` 透视图切换栏 ` 手动进行透视图切换，切换到其它透视图进行相关工作。

+
+
+#### 可关闭
+
+每个功能窗口标题旁边都有一个 `X` 可以通过点击该处，关闭功能窗口，如下图所示：
+
+
+
+若想再次打开已关闭的功能窗口，可通过菜单栏的 ` 窗口 ` 菜单的子菜单 ` 显示视图 ` 菜单中再次打开对应功能窗口，如果当前菜单中没显示想要打开的功能窗口，可以点击从 ` 其他 ` 菜单中查找。
+
+
+
+#### 最大化
+
+每个功能窗口都有自己单独的工具栏，工具栏最右边是最小化和最大化功能按钮，如下图所示：
+
+
+
+在功能窗口的标题上双击或者点击功能窗口栏上最大化按钮，即可将窗口最大化，占满整个功能窗口区域，其它窗口将会暂时最小化到侧栏内，如下图所示：
+
+
+
+再次双击 ` 项目资源管理器 ` 功能窗口即可恢复之前的功能窗口位置和状态。
+
+#### 最小化
+
+点击功能窗口最小化按钮，功能窗口将会暂时缩小到侧栏位置放置，点击 ` 恢复 ` 按钮即可恢复原来状态，如下图所示：
+
+
+
+### 工具栏按钮介绍

+
+
+
+#### SDK Manger
+
+`SDK Manger` 可以管理源码包、芯片支持包、开发板资源包、工具链资源包、调试工具包、第三方资源包，可以根据需要进行下载相应的资源。
+
+
+
+## 欢迎页
+
+RT-Thread Studio 每次启动打开软件主界面后会展示一个最大化的欢迎页窗口，如下图所示：
+
+
+
+欢迎页左侧有四个便利的功能入口：` 创建 RT-Thread 项目 `，`RT-Thread 论坛 `，` 视频教程 `，` 帮助文档 `，直接点击相应的功能名称即可使用对应功能。欢迎页右侧展示了三类内容：` 最新动态 `，` 视频教程 `，` 最新 PR`，点击对应的标签即可查看或者浏览对应标签页的内容。

+
+## 新建
+
+新建资源功能包括新建各类资源，例如工程，文件，文件夹等，新建入口有菜单，工具栏按钮，和工程右键菜单如下图所示：
+
+
+
+
+## 导入
+
+RT-Thread Studio 的导入功能不仅支持导入现有的 RT-Thread Studio 工程，还支持用户将 MDK/IAR 格式的工程导入到 RT-Thread Studio 中，便于用户迁移开发环境。
+
+### RT-Thread Studio 项目导入
+
+在 Studio 资源管理器窗口中点击右键，在下拉菜单中选择导入功能：
+
+
+
+打开导入功能向导，选择导入 RT-Thread Studio 工程：
+
+
+
+点击 **下一步** 后，点击 **浏览** 按钮选择要导入项目所在的工程目录，导入程序会自动扫描该目录下所有可导入的工程，将结果列出在项目列表中。在工程列表中勾选要导入的工程，然后点击 ` 完成 ` 即可。
+
+
+
+### MDK/IAR 项目导入
+
+开发者可以将现有的 RT-Thread MDK/IAR 工程直接导入到 RT-Thread Studio 中，然后就可以使用 RT-Thread Studio 提供的更多工程配置功能。
+
+`MDK/IAR` 工程在导入到 RT-Thread Studio 后，将有如下特性：
+
+- 保持原有项目的目录结构
+- 保持保持原有项目的源文件
+- 保持原有项目的头文件路径
+- 保持原有项目的宏定义
+- 将原工程中使用的 libc 库相关配置转换为 newlibc
+- 可以使用 RT-Thread Studio 提供的 RT-Thread 系统配置及软件包配置功能
+
+注意 ：目前仅支持 STM32 系列芯片的工程导入，后续会支持更多芯片。
+
+#### 导入示例
+
+本小节将以 `bsp/stm32/stm32f429-atk-apollo` 工程为例，演示如何导入一个 MDK 工程到 RT-Thread Studio 中，导入前工程目录如下图所示：
+
+
+
+在 Studio 资源管理器窗口中点击右键，在下拉菜单中选择导入功能，然后选择导入 MDK/IAR 项目到工作空间，然后点击下一步， 如下图所示：
+
+
+
+点击浏览选择工程目录下要导入的 MDK/IAR 工程，然后输入导入后的工程名，点击完成即可， 如下图所示：
+
+
+
+导入成功后，会在原工程目录下创建 RT-Thread Studio 的工程目录文件夹，如下图所示：
+
+
+
+项目资源管理器此时显示界面， 如下图所示 ：
+
+
+
+此时直接点击编译按钮编译成功后，如下图所示：
+
+
+
+#### 导入工程管理
+
+当一个 MDK/IAR 工程被导入到 RT-Thread Studio 之后，原工程的组织结构会保持不变，如下图所示：
+
+
+
+与原 MDK 工程相同，RT-Thread Studio Group 中的源文件也可以存放在工程的各个位置，而不必实际上按照这种组织结构而存放文件。
+
+可以注意到导入的 Group 和源文件右下角有一个小方块和箭头指示，表示区别于原生 eclipse 那种所见即所得的文件组织形式。这种右下角带方框或者箭头标识的文件夹或者文件，在 RT-Thread Studio 中分别称为虚拟文件夹和链接文件。
+
+##### 添加与删除源文件
+
+如果想在导入的工程中添加源文件，此时只需要保证该文件存在于工程目录中，然后手动拖入到相应的 group 中。如果想要从工程中删除某个源文件，则可以右键点击该文件，在下拉菜单中选择删除即可，如下图所示：
+
+
+
+即可在工程中看到 README.md 文件：
+
+
+
+如果想要创建一个虚拟文件夹 (虚拟文件夹并不是真实存在的文件夹，并没有实际的逻辑结构，其显示的内容可能实际上是分散于若干个真实的文件夹中，虚拟文件夹只是起到了一个归纳和汇总的作用)，可以采用如下方式：
+
+
+
+
+
+即可在工程中看到新创建的文件夹：
+
+
+
+#### 导入错误说明
+
+本小节将介绍在导入过程中可能出现的错误，以及遇到这类问题该如何解决。由于在导入的过程中要根据用户所导入的工程进行芯片检查以及一些文件的替换，有时会遇到芯片不支持或者文件找不到的情况，此时用户可以自行手动替换某些缺少的文件，使得工程可以构建成功。
+
+常见的错误提示信息如下：
+
+- **ERROR STM32MP157AAAx doesn't support import to RT-Thread Studio now**
+
+ 说明 RT-Thread Studio 暂不支持导入当前系列的芯片。
+
+- **ERROR get IAR version failed. Please update the IAR installation path in rtconfig.py!**
+
+ 说明找不到 IAR 的安装路径 打开工程目录下 rtconfig.py 文件 ， 修改 IAR 的 **EXEC_PATH** 。
+
+ ```c
+ elif CROSS_TOOL == 'iar':
+ PLATFORM = 'iar'
+ EXEC_PATH = r'C:/Program Files (x86)/IAR Systems/Embedded Workbench 8.0'
+ ```
+
+- **WARNING Can't auto specific link.lds file, Please specific a linker file mannually.**
+
+ 出现这种错误意味着在导入过程中不能自动替换链接脚本文件，需要手动指定链接脚本的位置。
+
+ 
+
+- **WARNING Can't find xxx_startup_stm32fxxx.s, replace startup files failed.**
+
+ 出现这种错误意味着在导入过程中不能找到可自动替换的芯片启动文件，需要手动添加启动文件到工程中。此时直接将可用的 gcc 启动文件拷贝到工程中，然后拖到相应的 group 中即可。
+

+# SCons 构建工具
+
+## SCons 简介
+
+SCons 是一套由 Python 语言编写的开源构建系统，类似于 GNU Make。它采用不同于通常 Makefile 文件的方式，而是使用 SConstruct 和 SConscript 文件来替代。这些文件也是 Python 脚本，能够使用标准的 Python 语法来编写。所以在 SConstruct、SConscript 文件中可以调用 Python 标准库进行各类复杂的处理，而不局限于 Makefile 设定的规则。
+
+在 [SCons](http://www.scons.org/doc/production/HTML/scons-user/index.html) 的网站上可以找到详细的 SCons 用户手册，本章节讲述 SCons 的基本用法，以及如何在 RT-Thread 中用好 SCons 工具。
+
+### 什么是构建工具
+
+构建工具 (software construction tool) 是一种软件，它可以根据一定的规则或指令，将源代码编译成可执行的二进制程序。这是构建工具最基本也是最重要的功能。实际上构建工具的功能不止于此，通常这些规则有一定的语法，并组织成文件。这些文件用来控制构建工具的行为，在完成软件构建之外，也可以做其他事情。
+
+目前最流行的构建工具是 GNU Make。很多知名开源软件，如 Linux 内核就采用 Make 构建。Make 通过读取 Makefile 文件来检测文件的组织结构和依赖关系，并完成 Makefile 中所指定的命令。
+
+由于历史原因，Makefile 的语法比较混乱，不利于初学者学习。此外在 Windows 平台上使用 Make 也不方便，需要安装 Cygwin 环境。为了克服 Make 的种种缺点，人们开发了其他构建工具，如 CMake 和 SCons 等。
+
+### RT-Thread 构建工具
+
+RT-Thread 早期使用 Make/Makefile 构建。从 0.3.x 开始，RT-Thread 开发团队逐渐引入了 SCons 构建系统，引入 SCons 唯一的目是：使大家从复杂的 Makefile 配置、IDE 配置中脱离出来，把精力集中在 RT-Thread 功能开发上。
+
+有些读者可能会有些疑惑，这里介绍的构建工具与 IDE 有什么不同呢？IDE 通过图形化界面的操作来完成构建。大部分 IDE 会根据用户所添加的源码生成类似 Makefile 或 SConscript 的脚本文件，在底层调用类似 Make 或 SCons 的工具来构建源码。
+
+### 安装 SCons
+
+在使用 SCons 系统前需要在 PC 主机中安装它，因为它是 Python 语言编写的，所以在使用 SCons 之前需要安装 Python 运行环境。
+
+RT-Thread 提供的 Env 配置工具带有 SCons 和 Python，因此在 windows 平台使用 SCons 则不需要安装这两个软件。
+
+在 Linux、BSD 环境中 Python 应该已经默认安装了，一般也是 2.x 版本系列的 Python 环境。这时只需要安装 SCons 即可，例如在 Ubuntu 中可以使用如下命令安装 SCons：
+
+`sudo apt-get install scons`
+
+## SCons 基本功能
+
+RT-Thread 构建系统支持多种编译器。目前支持的编译器包括 ARM GCC、MDK、IAR、VisualStudio、Visual DSP。主流的 ARM Cortex M0、M3、M4 平台，基本上 ARM GCC、MDK、IAR 都是支持的。有一些 BSP 可能仅支持一种，读者可以阅读该 BSP 目录下的 rtconfig.py 里的 CROSS_TOOL 选项查看当前支持的编译器。
+
+如果是 ARM 平台的芯片，则可以使用 Env 工具，输入 scons 命令直接编译 BSP，这时候默认使用的是 ARM GCC 编译器，因为 Env 工具带有 ARM GCC 编译器。 如下图所示使用 `scons` 命令编译 stm32f10x-HAL BSP，后文讲解 SCons 也将基于这个 BSP。
+
+
+
+如果用户要使用其他的 BSP 已经支持的编译器编译工程，或者 BSP 为非 ARM 平台的芯片，那么不能直接使用 scons 命令编译工程，需要自己安装对应的编译器，并且指定使用的编译器路径。在编译工程前，可以在 Env 命令行界面使用下面的 2 个命令指定编译器为 MDK 和编译器路径为 MDK 的安装路径。
+
+```c
+set RTT_CC=keil
+set RTT_EXEC_PATH=C:/Keilv5
+```
+
+### SCons 基本命令
+
+本节介绍 RT-Thread 中常用的 SCons 命令。SCons 不仅完成基本的编译，还可以生成 MDK/IAR/VS 工程。
+
+#### scons
+
+在 Env 命令行窗口进入要编译的 BSP 工程目录，然后使用此命令可以直接编译工程。如果执行过 `scons` 命令后修改了一些源文件，再次执行 scons 命令时，则 SCons 会进行增量编译，仅编译修改过的源文件并链接。
+
+如果在 Windows 上执行 `scons` 输出以下的警告信息：
+
+```c
+scons: warning: No version of Visual Studio compiler found - C/C++ compilers most likely not set correctly.
+```
+
+说明 scons 并没在你的机器上找到 Visual Studio 编译器，但实际上我们主要是针对设备开发，和 Windows 本地没什么关系，请直接忽略掉它。
+
+`scons` 命令后面还可以增加一个 - s 参数，即命令 `scons -s`，和 scons 命令不同的是此命令不会打印具体的内部命令。
+
+#### scons -c
+
+清除编译目标。这个命令会清除执行 scons 时生成的临时文件和目标文件。
+
+#### scons --target=XXX
+
+如果使用 mdk/iar 来进行项目开发，当修改了 rtconfig.h 打开或者关闭某些组件时，需要使用以下命令中的其中一种重新生成对应的定制化的工程，然后在 mdk/iar 进行编译下载。
+
+```c
+scons --target=iar
+scons --target=mdk4
+scons --target=mdk5
+```
+
+在命令行窗口进入要编译的 BSP 工程目录，使用 `scons --target=mdk5` 命令后会在 BSP 目录生成一个新的 MDK 工程文件名为 project.uvprojx。双击它打开，就可以使用 MDK 来编译、调试。使用 `scons --target=iar` 命令后则会生成一个新的 IAR 工程文件名为 project.eww。不习惯 SCons 的用户可以使用这种方式。如果打开 project.uvproj 失败，请删除 project.uvopt 后，重新生成工程。
+
+在 bsp/simulator 下，可以使用下面的命令生成 vs2012 的工程或 vs2005 的工程。
+
+```c
+scons --target=vs2012
+Scons --target=vs2005
+```
+
+如果 BSP 目录下提供其他 IDE 工程的模板文件也可以使用此命令生成对应的新工程，比如 ua、vs、cb、cdk。
+
+这个命令后面同样可以增加一个 -s 参数，如命令 `scons –target=mdk5 -s`，执行此命令时不会打印具体的内部命令。
+
+> [!NOTE]
+> 注：要生成 MDK 或者 IAR 的工程文件，前提条件是 BSP 目录存在一个工程模版文件，然后 scons 才会根据这份模版文件加入相关的源码，头文件搜索路径，编译参数，链接参数等。而至于这个工程是针对哪颗芯片的，则直接由这份工程模版文件指定。所以大多数情况下，这个模版文件是一份空的工程文件，用于辅助 SCons 生成 project.uvprojx 或者 project.eww。
+
+#### scons -jN
+
+多线程编译目标，在多核计算机上可以使用此命令加快编译速度。一般来说一颗 cpu 核心可以支持 2 个线程。双核机器上使用 `scons -j4` 命令即可。
+
+> [!NOTE]
+> 注：如果你只是想看看编译错误或警告，最好是不使用 - j 参数，这样错误信息不会因为多个文件并行编译而导致出错信息夹杂在一起。
+
+#### scons --dist
+
+搭建项目框架，使用此命令会在 BSP 目录下生成 dist 目录，这便是开发项目的目录结构，包含了RT-Thread源码及BSP相关工程，不相关的BSP文件夹及libcpu都会被移除，并且可以随意拷贝此工程到任何目录下使用。
+
+#### scons --verbose
+
+默认情况下，使用 scons 命令编译的输出不会显示编译参数，如下所示：
+
+```c
+D:\repository\rt-thread\bsp\stm32f10x>scons
+scons: Reading SConscript files ...
+scons: done reading SConscript files.
+scons: Building targets ...
+scons: building associated VariantDir targets: build
+CC build\applications\application.o
+CC build\applications\startup.o
+CC build\components\drivers\serial\serial.o
+...
+```
+
+使用 scons –verbose 命令的效果如下：
+
+```c
+armcc -o build\src\mempool.o -c --device DARMSTM --apcs=interwork -ID:/Keil/ARM/
+RV31/INC -g -O0 -DUSE_STDPERIPH_DRIVER -DSTM32F10X_HD -Iapplications -IF:\Projec

+...
+```
+
+## SCons 进阶
+
+SCons 使用 SConscript 和 SConstruct 文件来组织源码结构，通常来说一个项目只有一 SConstruct，但是会有多个 SConscript。一般情况下，每个存放有源代码的子目录下都会放置一个 SConscript。
+
+为了使 RT-Thread 更好的支持多种编译器，以及方便的调整编译参数，RT-Thread 为每个 BSP 单独创建了一个名为 rtconfig.py 的文件。因此每一个 RT-Thread BSP 目录下都会存在下面三个文件：rtconfig.py、SConstruct 和 SConscript，它们控制 BSP 的编译。一个 BSP 中只有一个 SConstruct 文件，但是却会有多个 SConscript 文件，可以说 SConscript 文件是组织源码的主力军。
+
+RT-Thread 大部分源码文件夹下也存在 SConscript 文件，这些文件会被 BSP 目录下的 SConscript 文件 “找到” 从而将 rtconfig.h 中定义的宏对应的源代码加入到编译器中来。后文将以 stm32f10x-HAL BSP 为例，讲解 SCons 是如何构建工程。
+
+### SCons 内置函数
+
+如果想要将自己的一些源代码加入到 SCons 编译环境中，一般可以创建或修改已有 SConscript 文件。SConscript 文件可以控制源码文件的加入，并且可以指定文件的 Group（与 MDK/IAR 等 IDE 中的 Group 的概念类似）。
+
+SCons 提供了很多内置函数可以帮助我们快速添加源码程序，利用这些函数，再配合一些简单的 Python 语句我们就能随心所欲向项目中添加或者删除源码。下面将简单介绍一些常用函数。
+
+#### GetCurrentDir()
+
+获取当前路径。
+
+#### Glob('\*.c')
+
+获取当前目录下的所有 C 文件。修改参数的值为其他后缀就可以匹配当前目录下的所有某类型的文件。
+
+#### GetDepend(macro)
+
+该函数定义在 tools 目录下的脚本文件中，它会从 rtconfig.h 文件读取配置信息，其参数为 rtconfig.h 中的宏名。如果 rtconfig.h 打开了某个宏，则这个方法（函数）返回真，否则返回假。
+
+#### Split(str)
+
+将字符串 str 分割成一个列表 list。
+
+#### DefineGroup(name， src， depend，**parameters)
+
+这是 RT-Thread 基于 SCons 扩展的一个方法（函数）。DefineGroup 用于定义一个组件。组件可以是一个目录（下的文件或子目录），也是后续一些 IDE 工程文件中的一个 Group 或文件夹。
+
+`DefineGroup() ` 函数的参数描述：
+
+|**参数**|**描述** |
+|-------|------------------------------------|
+| name | Group 的名字 |
+| src | Group 中包含的文件，一般指的是 C/C++ 源文件。方便起见，也能够通过 Glob 函数采用通配符的方式列出 SConscript 文件所在目录中匹配的文件 |
+| depend | Group 编译时所依赖的选项（例如 FinSH 组件依赖于 RT_USING_FINSH 宏定义）。编译选项一般指 rtconfig.h 中定义的 RT_USING_xxx 宏。当在 rtconfig.h 配置文件中定义了相应宏时，那么这个 Group 才会被加入到编译环境中进行编译。如果依赖的宏并没在 rtconfig.h 中被定义，那么这个 Group 将不会被加入编译。相类似的，在使用 scons 生成为 IDE 工程文件时，如果依赖的宏未被定义，相应的 Group 也不会在工程文件中出现 |
+| parameters | 配置其他参数，可取值见下表，实际使用时不需要配置所有参数 |
+
+parameters 可加入的参数：
+
+|**参数**|**描述** |
+|------------|--------------------------------------------------|
+| CCFLAGS | C 源文件编译参数 |
+| CPPPATH | 头文件路径 |
+| CPPDEFINES | 链接时参数 |
+| LIBRARY | 包含此参数，则会将组件生成的目标文件打包成库文件 |
+
+#### SConscript(dirs，variant_dir，duplicate)
+
+读取新的 SConscript 文件，SConscript() 函数的参数描述如下所示：
+
+|**参数** |**描述** |
+|-------------|---------------------------------------|
+| dirs | SConscript 文件路径 |
+| variant_dir | 指定生成的目标文件的存放路径 |
+| duiplicate | 设定是否拷贝或链接源文件到 variant_dir |
+
+## SConscript 示例
+
+下面我们将以几个 SConscript 为例讲解 scons 构建工具的使用方法。
+
+### SConscript 示例 1
+
+我们先从 stm32f10x-HAL BSP 目录下的 SConcript 文件开始讲解，这个文件管理 BSP 下面的所有其他 SConscript 文件，内容如下所示。
+
+```c
+import os
+cwd = str(Dir('#'))
+objs = []
+list = os.listdir(cwd)
+for d in list:
+ path = os.path.join(cwd， d)
+ if os.path.isfile(os.path.join(path， 'SConscript')):
+ objs = objs + SConscript(os.path.join(d， 'SConscript'))
+Return('objs')
+```
+
+* `import os:` 导入 Python 系统编程 os 模块，可以调用 os 模块提供的函数用于处理文件和目录。
+
+* `cwd = str(Dir('#'))：` 获取工程的顶级目录并赋值给字符串变量 cwd，也就是工程的 SConstruct 所在的目录，在这里它的效果与 `cwd = GetCurrentDir()` 相同。
+
+* `objs = []:` 定义了一个空的 list 型变量 objs。
+
+* `list = os.listdir(cwd)：` 得到当前目录下的所有子目录，并保存到变量 list 中。
+
+* 随后是一个 python 的 for 循环，这个 for 循环会遍历一遍 BSP 的所有子目录并运行这些子目录的 SConscript 文件。具体操作是取出一个当前目录的子目录，利用 `os.path.join(cwd，d)` 拼接成一个完整路径，然后判断这个子目录是否存在一个名为 SConscript 的文件，若存在则执行 `objs = objs + SConscript(os.path.join(d，'SConscript'))。` 这一句中使用了 SCons 提供的一个内置函数 `SConscript()`，它可以读入一个新的 SConscript 文件，并将 SConscript 文件中所指明的源码加入到了源码编译列表 objs 中来。
+
+通过这个 SConscript 文件，BSP 工程所需要的源代码就被加入了编译列表中。
+
+### SConscript 示例 2
+
+那么 stm32f10x-HAL BSP 其他的 SConcript 文件又是怎样的呢？我们再看一下 drivers 目录下 SConcript 文件，这个文件将管理 drivers 目录下面的源代码。drivers 目录用于存放根据 RT-Thread 提供的驱动框架实现的底层驱动代码。
+
+```c
+Import('rtconfig')
+from building import *
+
+cwd = GetCurrentDir()
+
+# add the general drivers.
+src = Split("""
+board.c
+stm32f1xx_it.c
+""")
+
+if GetDepend(['RT_USING_PIN']):
+ src += ['drv_gpio.c']
+if GetDepend(['RT_USING_SERIAL']):
+ src += ['drv_usart.c']
+if GetDepend(['RT_USING_SPI']):
+ src += ['drv_spi.c']
+if GetDepend(['RT_USING_USB_DEVICE']):
+ src += ['drv_usb.c']
+if GetDepend(['RT_USING_SDCARD']):
+ src += ['drv_sdcard.c']
+
+if rtconfig.CROSS_TOOL == 'gcc':
+ src += ['gcc_startup.s']
+
+CPPPATH = [cwd]
+
+group = DefineGroup('Drivers', src, depend = [''], CPPPATH = CPPPATH)
+
+Return('group')
+
+```
+
+* `Import('rtconfig')：` 导入 rtconfig 对象，后面用到的 rtconfig.CROSS_TOOL 定义在这个 rtconfig 模块。
+
+* `from building import *：` 把 building 模块的所有内容全都导入到当前模块，后面用到的 DefineGroup 定义在这个模块。
+
+* `cwd = GetCurrentDir()：` 获得当前路径并保存到字符串变量 cwd 中。
+
+后面一行使用 `Split()` 函数来将一个文件字符串分割成一个列表，其效果等价于
+
+`src = ['board.c'，'stm32f1xx_it.c']`
+
+后面使用了 if 判断和 `GetDepend()` 检查 rtconfig.h 中的某个宏是否打开，如果打开，则使用 `src += [src_name]` 来往列表变量 src 中追加源代码文件。
+
+* `CPPPATH = [cwd]：` 将当前路径保存到一个列表变量 CPPPATH 中。
+
+最后一行使用 DefineGroup 创建一个名为 Drivers 的组，这个组也就对应 MDK 或者 IAR 中的分组。这个组的源代码文件为 src 指定的文件，depend 为空表示该组不依赖任何 rtconfig.h 的宏。
+
+`CPPPATH =CPPPATH` 表示将当前路径添加到系统的头文件路径中。左边的 CPPPATH 是 DefineGroup 中内置参数，表示头文件路径。右边的 CPPPATH 是本文件上面一行定义的。这样我们就可以在其他源码中引用 drivers 目录下的头文件了。
+
+### SConscript 示例 3
+
+我们再看一下 applications 目录下的 SConcript 文件，这个文件将管理 applications 目录下面的源代码，用于存放用户自己的应用代码。
+
+```c
+from building import *
+
+cwd = GetCurrentDir()
+src = Glob('*.c')
+CPPPATH = [cwd, str(Dir('#'))]
+
+group = DefineGroup('Applications', src, depend = [''], CPPPATH = CPPPATH)
+
+Return('group')
+```
+
+`src = Glob('*.c')：` 得到当前目录下所有的 C 文件。
+
+`CPPPATH = [cwd, str(Dir('#'))]：` 将当前路径和工程的 SConstruct 所在的路径保存到列表变量 CPPPATH 中。
+
+最后一行使用 DefineGroup 创建一个名为 Applications 的组。这个组的源代码文件为 src 指定的文件，depend 为空表示该组不依赖任何 rtconfig.h 的宏，并将 CPPPATH 保存的路径添加到了系统头文件搜索路径中。这样 applications 目录和 stm32f10x-HAL BSP 目录里面的头文件在源代码的其他地方就可以引用了。
+
+总结：这个源程序会将当前目录下的所有 c 程序加入到组 Applications 中，因此如果在这个目录下增加或者删除文件，就可以将文件加入工程或者从工程中删除。它适用于批量添加源码文件。
+
+### SConscript 示例 4
+
+下面是 RT-Thread 源代码 component/finsh/SConscript 文件的内容，这个文件将管理 finsh 目录下面的源代码。
+
+```c
+Import('rtconfig')
+from building import *
+
+cwd = GetCurrentDir()
+src = Split('''
+shell.c
+symbol.c
+cmd.c
+''')
+
+fsh_src = Split('''
+finsh_compiler.c
+finsh_error.c
+finsh_heap.c
+finsh_init.c
+finsh_node.c
+finsh_ops.c
+finsh_parser.c
+finsh_var.c
+finsh_vm.c
+finsh_token.c
+''')
+
+msh_src = Split('''
+msh.c
+msh_cmd.c
+msh_file.c
+''')
+
+CPPPATH = [cwd]
+if rtconfig.CROSS_TOOL == 'keil':
+ LINKFLAGS = '--keep *.o(FSymTab)'
+
+ if not GetDepend('FINSH_USING_MSH_ONLY'):
+ LINKFLAGS = LINKFLAGS + '--keep *.o(VSymTab)'
+else:
+ LINKFLAGS = ''
+
+if GetDepend('FINSH_USING_MSH'):
+ src = src + msh_src
+if not GetDepend('FINSH_USING_MSH_ONLY'):
+ src = src + fsh_src
+
+group = DefineGroup('finsh', src, depend = ['RT_USING_FINSH'], CPPPATH = CPPPATH, LINKFLAGS = LINKFLAGS)
+
+Return('group')
+```
+
+我们来看一下文件中第一个 Python 条件判断语句的内容，如果编译工具是 keil，则变量 `LINKFLAGS = '--keep *.o(FSymTab)'` 否则置空。
+
+DefinGroup 同样将 finsh 目录下的 src 指定的文件创建为 finsh 组。`depend = ['RT_USING_FINSH']` 表示这个组依赖 rtconfig.h 中的宏 RT_USING_FINSH。当 rtconfig.h 中打开宏 RT_USING_FINSH 时，finsh 组内的源码才会被实际编译，否则 SCons 不会编译。
+
+然后将 finsh 目录加入到系统头文件目录中，这样我们就可以在其他源码中引用 finsh 目录下的头文件。
+
+`LINKFLAGS = LINKFLAGS` 的含义与 `CPPPATH = CPPPATH` 类似。左边的 LINKFLAGS 表示链接参数，右边的 LINKFLAGS 则是前面 if else 语句所定义的值。也就是给工程指定链接参数。
+
+## 使用 SCons 管理工程
+
+前面小节对 RT-Thread 源代码的相关 SConscript 做了详细讲解，大家也应该知道了 SConscript 文件的一些常见写法，本小节将指导大家如何使用 SCons 管理自己的工程。
+
+### 添加应用代码
+
+前文提到过 BSP 下的 Applications 文件夹用于存放用户自己的应用代码，目前只有一个 main.c 文件。如果用户的应用代码不是很多，建议相关源文件都放在这个文件夹下面。在 Applications 文件夹下新增了 2 个简单的文件 hello.c 和 hello.h，内容如下所示。
+
+```c
+/* file: hello.h */
+
+#ifndef _HELLO_H_
+#define _HELLO_H_
+
+int hello_world(void);
+
+#endif /* _HELLO_H_ */
+
+/* file: hello.c */
+#include <stdio.h>
+#include <finsh.h>
+#include <rtthread.h>
+
+int hello_world(void)
+{
+ rt_kprintf("Hello, world!\n");
+
+ return 0;
+}
+
+MSH_CMD_EXPORT(hello_world, Hello world!)
+```
+
+applications 目录下的 SConcript 文件会把当前目录下的所有源文件都添加到工程中。需要使用 `scons --target=xxx` 命令才会把新增的 2 个文件添加到工程项目中。注意每次新增文件都要重新生成工程。
+
+### 添加模块
+
+前文提到在自己源代码文件不多的情况下，建议所有源代码文件都放在 applications 文件夹里面。如果用户源代码很多了，并且想创建自己的工程模块，或者需要使用自己获取的其他模块，怎么做会比较合适呢？
+
+同样以上文提到的 hello.c 和 hello.h 为例，这两个文件将会放到一个单独的文件夹里管理，并且在 MDK 工程文件里有自己的分组，且可以通过 menuconfig 选择是否使用这个模块。在 BSP 下新增 hello 文件夹。
+
+
+
+大家注意到文件夹里多了一个 SConscript 文件，如果想要将自己的一些源代码加入到 SCons 编译环境中，一般可以创建或修改已有的 SConscript 文件。参考上文对 RT-Thread 源代码的一些对 SConscript 文件的分析，这个新增的 hello 模块 SConscript 文件内容如下所示：
+
+```c
+from building import *
+
+cwd = GetCurrentDir()
+include_path = [cwd]
+src = []
+
+if GetDepend(['RT_USING_HELLO']):
+ src += ['hello.c']
+
+group = DefineGroup('hello', src, depend = [''], CPPPATH = include_path)
+
+Return('group')
+```
+
+通过上面几行简单的代码，就创建了一个新组 hello，并且可以通过宏定义控制要加入到组里面的源文件，还将这个组所在的目录添加到了系统头文件路径中。那么自定义宏 RT_USING_HELLO 又是通过怎样的方式定义呢？这里要介绍一个新的文件 Kconfig。Kconfig 用来配置内核，使用 Env 配置系统时使用的 menuconfig 命令生成的配置界面就依赖 Kconfig 文件。menuconfig 命令通过读取工程的各个 Kconfig 文件，生成配置界面供用户配置内核，最后所有配置相关的宏定义都会自动保存到 BSP 目录里的 rtconfig.h 文件中，每一个 BSP 都有一个 rtconfig.h 文件，也就是这个 BSP 的配置信息。
+
+在 stm32f10x-HAL BSP 目录下已经有了关于这个 BSP 的 Kconfig 文件，我们可以基于这个文件添加自己需要的配置选项。关于 hello 模块添加了如下配置选项，# 号后面为注释。
+
+
+
+使用 Env 工具进入 stm32f10x-HAL BSP 目录后，使用 menuconfig 命令在主页面最下面就可以看到新增的 hello 模块的配置菜单，进入菜单后如下图所示。
+
+
+
+还可以修改 hello value 的值。
+
+
+
+保存配置后退出配置界面，打开 stm32f10x-HAL BSP 目录下的 rtconfig.h 文件可以看到 hello 模块的配置信息已经有了。
+
+
+
+**注意：每次 menuconfig 配置完成后都要使用 scons --target=XXX 命令生成新工程。**
+
+因为 rtconfig.h 中已经定义了 RT_USING_HELLO 宏，所以新生成工程时就会把 hello.c 的源文件添加到新工程中。
+
+上面只是简单列举了在 Kconfig 文件中添加自己模块的配置选项，用户还可以参考[《Env 用户手册》](../env/env.md)，里面也有对配置选项修改和添加的讲解，也可以自己百度查看 Kconfig 的相关文档，实现其他更复杂的配置选项。
+
+### 添加库
+
+如果要往工程中添加一个额外的库，需要注意不同的工具链对二进制库的命名。
+
+- ARMCC 工具链下的库名称应该是 xxx.lib，一个以 .lib 为后缀的文件。
+- IAR 工具链下的库名称应该是 xxx.a，一个以 .a 为后缀的文件。
+- GCC 工具链下的库名称应该是 libxxx.a，一个以 .a 为后缀的文件，并且有 lib 前缀。
+
+ARMCC / IAR 工具链下，若添加库名为 libabc.lib / libabc_iar.a 时，在指定库时指定全名 libabc。
+
+GCC 工具链比较特殊，它识别的是 libxxx.a 这样的库名称，若添加库名为 libabc.a 时，在指定库时是指定 abc，而不是 libabc。
+
+例如，`/libs` 下有以下库文件需要添加：
+
+```
+libabc_keil.lib
+libabc_iar.a
+libabc_gcc.a
+```
+
+则对应的 SConscript 如下：
+
+```
+Import('rtconfig')
+from building import *
+
+cwd = GetCurrentDir()
+src = Split('''
+''')
+
+LIBPATH = [cwd + '/libs'] # LIBPATH 指定库的路径，表示库的搜索路径是当前目录下的'libs'目录
+
+if rtconfig.CROSS_TOOL == 'gcc':
+ LIBS = ['abc_gcc'] # GCC 下 LIBS 指定库的名称
+elif rtconfig.CROSS_TOOL == 'keil':
+ LIBS = ['libabc_keil'] # ARMCC 下 LIBS 指定库的名称
+else:
+ LIBS = ['libabc_iar'] # IAR 下 LIBS 指定库的名称
+
+group = DefineGroup('ABC', src, depend = [''], LIBS = LIBS, LIBPATH=LIBPATH)
+
+Return('group')
+```
+
+### 编译器选项
+
+rtconfig.py 是一个 RT-Thread 标准的编译器配置文件，控制了大部分编译选项，是一个使用 python 语言编写的脚本文件，主要用于完成以下工作：
+
+* 指定编译器（从支持的多个编译器中选择一个你现在使用的编译器）。
+
+* 指定编译器参数，如编译选项、链接选项等。
+
+当我们使用 scons 命令编译工程时，就会按照 rtconfig.py 的编译器配置选项编译工程。下面的代码为 stm32f10x-HAL BSP 目录下 rtconfig.py 的部分代码。
+
+```c
+import os
+
+# toolchains options
+ARCH='arm'
+CPU='cortex-m3'
+CROSS_TOOL='gcc'
+
+if os.getenv('RTT_CC'):
+ CROSS_TOOL = os.getenv('RTT_CC')
+
+# cross_tool provides the cross compiler
+# EXEC_PATH is the compiler execute path, for example, CodeSourcery, Keil MDK, IAR
+
+if CROSS_TOOL == 'gcc':
+ PLATFORM = 'gcc'
+ EXEC_PATH = '/usr/local/gcc-arm-none-eabi-5_4-2016q3/bin/'
+elif CROSS_TOOL == 'keil':
+ PLATFORM = 'armcc'
+ EXEC_PATH = 'C:/Keilv5'
+elif CROSS_TOOL == 'iar':
+ PLATFORM = 'iar'
+ EXEC_PATH = 'C:/Program Files/IAR Systems/Embedded Workbench 6.0 Evaluation'
+
+if os.getenv('RTT_EXEC_PATH'):
+ EXEC_PATH = os.getenv('RTT_EXEC_PATH')
+
+BUILD = 'debug'
+
+if PLATFORM == 'gcc':
+ # toolchains
+ PREFIX = 'arm-none-eabi-'
+ CC = PREFIX + 'gcc'
+ AS = PREFIX + 'gcc'
+ AR = PREFIX + 'ar'
+ LINK = PREFIX + 'gcc'
+ TARGET_EXT = 'elf'
+ SIZE = PREFIX + 'size'
+ OBJDUMP = PREFIX + 'objdump'
+ OBJCPY = PREFIX + 'objcopy'
+
+ DEVICE = '-mcpu=cortex-m3 -mthumb -ffunction-sections -fdata-sections'
+ CFLAGS = DEVICE
+ AFLAGS = '-c' + DEVICE + '-x assembler-with-cpp'
+ LFLAGS = DEVICE + '-Wl,--gc-sections,-Map=rtthread-stm32.map,-cref,-u,Reset_Handler -T stm32_rom.ld'
+```
+
+其中 CFLAGS 是 C 文件的编译选项，AFLAGS 则是汇编文件的编译选项，LFLAGS 是链接选项。BUILD 变量控制代码优化的级别。默认 BUILD 变量取值为'debug'，即使用 debug 方式编译，优化级别 0。如果将这个变量修改为其他值，就会使用优化级别 2 编译。下面几种都是可行的写法（总之只要不是'debug'就可以了)。
+
+```c
+BUILD = ''
+BUILD = 'release'
+BUILD = 'hello， world'
+```
+
+建议在开发阶段都使用 debug 方式编译，不开优化，等产品稳定之后再考虑优化。
+
+关于这些选项的具体含义需要参考编译器手册，如上面使用的 armcc 是 MDK 的底层编译器。其编译选项的含义在 MDK help 中有详细说明。
+
+前文提到过如果用户执行 scons 命令时希望使用其他编译器编译工程，可以在 Env 的命令行端使用相关命令指定编译器和编译器路径。但是这样修改只对当前的 Env 进程有效，再次打开时又需要重新使用命令设置，我们可以直接修改 rtconfig.py 文件达到永久配置编译器的目的。一般来说，我们只需要修改 CROSS_TOOL 和下面的 EXEC_PATH 两个选项。
+
+* CROSS_TOOL：指定编译器。可选的值有 keil、gcc、iar，浏览 rtconfig.py 可以查看当前 BSP 所支持的编译器。如果您的机器上安装了 MDK，那么可以将 CROSS_TOOL 修改为 keil，则使用 MDK 编译工程。
+
+* EXEC_PATH：编译器的安装路径。这里有两点需要注意：
+
+安装编译器时（如 MDK、GNU GCC、IAR 等），不要安装到带有中文或者空格的路径中。否则，某些解析路径时会出现错误。有些程序默认会安装到 `C:\Program Files` 目录下，中间带有空格。建议安装时选择其他路径，养成良好的开发习惯。
+
+修改 EXEC_PATH 时，需要注意路径的格式。在 windows 平台上，默认的路径分割符号是反斜杠 `“\”`，而这个符号在 C 语言以及 Python 中都是用于转义字符的。所以修改路径时，可以将`“\”` 改为 `“/”`，或者在前面加 r（python 特有的语法，表示原始数据）。
+
+假如某编译器安装位置为 `D:\Dir1\Dir2` 下。下面几种是正确的写法:
+
+* EXEC_PATH = `r'D:\Dir1\Dir2'` 注意，字符串前带有 r，则可正常使用 `“\”`。
+
+* EXEC_PATH = `'D:/Dir1/Dir2'` 注意，改用 `“/”`，前面没有 r。
+
+* EXEC_PATH = `'D:\\Dir1\\Dir2'` 注意，这里使用 `“\”` 的转义性来转义 `“\”` 自己。
+
+* 这是错误的写法：EXEC_PATH = `'D:\Dir1\Dir2'`。
+
+如果 rtconfig.py 文件有以下代码，在配置自己的编译器时请将下列代码注释掉。
+
+```c
+if os.getenv('RTT_CC'):
+ CROSS_TOOL = os.getenv('RTT_CC')
+... ...
+if os.getenv('RTT_EXEC_PATH'):
+ EXEC_PATH = os.getenv('RTT_EXEC_PATH')
+```
+
+上面 2 个 if 判断会设置 CROSS_TOOL 和 EXEC_PATH 为 Env 的默认值。
+
+编译器配置完成之后，我们就可以使用 SCons 来编译 RT-Thread 的 BSP 了。在 BSP 目录打开命令行窗口，执行 `scons` 命令就会启动编译过程。
+
+### RT-Thread 辅助编译脚本
+
+在 RT-Thread 源代码的 tools 目录下存放有 RT-Thread 自己定义的一些辅助编译的脚本，例如用于自动生成 RT-Thread 针对一些 IDE 集成开发环境的工程文件。其中最主要的是 building.py 脚本。
+
+### SCons 更多使用
+
+对于复杂、大型的系统，显然不仅仅是一个目录下的几个文件就可以搞定的，很可能是由数个文件夹一级一级组合而成。
+
+在 SCons 中，可以编写 SConscript 脚本文件来编译这些相对独立目录中的文件，同时也可以使用 SCons 中的 Export 和 Import 函数在 SConstruct 与 SConscript 文件之间共享数据（也就是 Python 中的一个对象数据）。更多 SCons 的使用方法请参考 [SCons 官方文档](https://scons.org/documentation.html)。
