1.安装Thonny(Thonny安装包)
2.按住Raspberry Pi Pico的“BOOTSEL”键,然后上电,上电后松开
3.电脑会出现一个新的盘符,将固件(Raspberry Pi Pico固件)解压,并将固件(后缀为uf2)拷贝至该磁盘(拷贝成功磁盘会自动消失)
4.开启Thonny,点击右下方的“Python x.x.x”,选择“Configure interpreter”
5.在弹出窗口中选择“解释器”->解释器选择“MicroPython(Raspbeery Pi Pico)”->端口选择“自动探测端口”
6.点击暂停,Shell窗口出现“MicroPython v1.20.0-50-g786013d46 on 2023-05-04; Raspberry Pi Pico with RP2040 Type "help()" for more information.”即为连接成功
