串口驱动安装
1.开发板使用的串口芯片为 CH340C,如果没有安装过CH340驱动,需要安装驱动
![](https://img2020.cnblogs.com/blog/819239/202012/819239-20201206235409087-409352421.png)
2.安装步骤
![](https://img2020.cnblogs.com/blog/819239/202012/819239-20201206235451871-1912473946.png)
3.使用USB线(Micro)连接开发板
![](https://img2020.cnblogs.com/blog/819239/202012/819239-20201206235808914-659706494.png)
4.如果电脑提示安装硬件驱动 ,等待安装完成,然后右击 "我的电脑" 选择管理
![](https://img2020.cnblogs.com/blog/819239/202012/819239-20201206235937602-725338847.png)
5.点击设备管理器,点击端口 查看当前电脑和开发板通信的端口号
我的为 COM4 (不同的电脑端口号不一样,只要有端口号就可以)

下载单片机程序(SWD方式)
预留了SWD接口下载单片机程序,用户可以使用ST-LINK或Jlink下载
