NPK方式进行组织，请下载最新的Nuclei Studio版本[https://www.nucleisys.com/download.php] 配合使用。 - **导入SDK**：打开Nuclei Studio IDE，选择菜单栏 RV-Tools->Nuclei Package Management，打开包管理窗口，导入SDK压缩包“CMIOT.CM32M4xxR_Library.zip”，注意必须是zip压缩格式，然后等待导入完成。导入完成后，包管理窗口会显示sdk-cm32m4xxr的包信息，如下图：
- **创建工程**：关闭包管理窗口，然后选择菜单栏File->New->New Nuclei RISC-V C/C++ Project，打开工程创建窗口。窗口左边列出了开发板的型号，用户可以根据自己的需求进行点击选择，右边是相关技术文档链接，包括芯片手册、软件说明、开发板使用指南、原理图等内容。然后点击next，继续进行工程创建。
　　自定义填写工程名称，由于开发板提供的样例工程比较多，可以选择过滤方式keywords，然后选择GPIO关键词进行筛选，之后可以在Project Example行选择GPIO相关工程。其他选项保持默认即可。点击Finish完成工程创建。
- **编译调试**：选择菜单栏Project->Build All进行工程编译，编译完成后，显示如下：
　　菜单栏选择Run->Debug Configurations打开调试配置界面。样例工程中已经完成了调试配置，用户可以不用修改，仅需选择适合自己的调试配置进行使用。通过NPK方式导入的工程一共有三种调试配置，分别对应Jlink、蜂鸟和CM-Link调试支持。检查开发板供电和调试器连接，然后点击Debug Configurations，选择对应的调试配置，然后点击下面的Debug按钮，即可启动工程调试。
　　调试视图1号位置为调试控制栏；2号位置为Registers窗口，可以查看RSIC-V内核的寄存器数值；3号位置为Peripherals窗口，可以选择查看MCU各个片上外设的寄存器，勾选其中一个外设以后，就会在Memory窗口中显示该外设的寄存器内容。以上窗口可以通过菜单栏Windows->Show View中找到并打开。其他如变量查看、断点增删等内容不在此赘述。
　　点击调试控制栏里的运行按钮，然后启动程序运行，可以观察到开发板上三个LED进行闪烁。 　每个样例工程的目录下都配套一个readme.txt文件，该文件介绍了样例工程的功能说明、使用方法、注意事项等内容，建议详细阅读。 - **下载**：Nuclei Studio IDE没有单独的下载按钮功能，在启动调试的过程中，IDE会根据链接文件的配置将程序下载到特定的位置，如将程序烧写到flash，请在编译配置选项界面选择gcc_cm32m4xxr_flashxip.ld文件，并修改DOWNLOAD_MODE的宏值为0。
