STM32F103ZET6小系统板 BSP 说明

简介

本文档是 嵌入式开发网的 STM32F103ZET6小系统板的 BSP (板级支持包) 说明。

主要内容如下:

  • 开发板资源介绍
  • BSP 快速上手
  • 进阶使用方法

通过阅读快速上手章节开发者可以快速地上手该 BSP,将 RT-Thread 运行在开发板上。在进阶使用指南章节,将会介绍更多高级功能,帮助开发者利用 RT-Thread 驱动更多板载资源。

开发板介绍

STM32F103ZET6小系统板是嵌入式开发网的一款基于 ARM Cortex-M3 内核的开发板,最高主频为 72Mhz,该开发板具有丰富的板载资源,可以充分发挥 STM32F103 的芯片性能。

开发板外观如下图所示:

使用说明

使用说明分为如下两个章节:

  • 快速上手

    本章节是为刚接触 RT-Thread 的新手准备的使用说明,遵循简单的步骤即可将 RT-Thread 操作系统运行在该开发板上,看到实验效果 。

  • 进阶使用

    本章节是为需要在 RT-Thread 操作系统上使用更多开发板资源的开发者准备的。通过使用 ENV 工具对 BSP 进行配置,可以开启更多板载资源,实现更多高级功能。

快速上手

本 BSP 为开发者提供 MDK4、MDK5 和 IAR 工程,并且支持 GCC 开发环境。下面以 MDK5 开发环境为例,介绍如何将系统运行起来。

硬件连接

使用数据线连接开发板到 PC,打开电源开关。

编译下载

双击 project.uvprojx 文件,打开 MDK5 工程,编译并下载程序到开发板。

工程默认配置使用 st-link 仿真器下载程序,在通过 st-link 连接开发板的基础上,点击下载按钮即可下载程序到开发板

运行结果

下载程序成功之后,系统会自动运行,LED 闪烁。

连接开发板对应串口到 PC , 在终端工具里打开相应的串口(115200-8-1-N),复位设备后,可以看到 RT-Thread 的输出信息:

 \ | /
- RT -     Thread Operating System
 / | \     4.0.1 build Apr  9 2019
 2006 - 2019 Copyright by rt-thread team
msh >

进阶使用

此 BSP 默认只开启了 GPIO 和 串口1 的功能,如果需使用 SD 卡、Flash 等更多高级功能,需要利用 ENV 工具对BSP 进行配置,步骤如下:

  1. 在 bsp 下打开 env 工具。

  2. 输入menuconfig命令配置工程,配置好之后保存退出。

  3. 输入pkgs --update命令更新软件包。

  4. 输入scons --target=mdk4/mdk5/iar 命令重新生成工程。

本章节更多详细的介绍请参考 STM32 系列 BSP 外设驱动使用教程

注意事项

  • 这款开发板使用终端工具 SecureCRT 来打开串口会出现系统不能启动的问题(需要在配置里关闭流控)。
