esp32 刷Micropython固件并连接 wifi
进入http://www.micropython.org/download/esp32/ 下载
esp32-idf3-20191220-v1.12.bin
先管理员进入powerShell，安装esptool，pip3 install esptool 如果esptool命令无效，在下列地址找到esptool安装目录：
C:\Users\战鹰Ryan\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\Scripts
将esptool.py拷贝到工作目录win10borad文件夹
然后擦除芯片
esptool --chip esp32 --port COM10 erase_flash （设置自己的COM口）
记得要摁板子上的boot键，才能开始擦除
PS C:\Users\战鹰Ryan\win10board> esptool --chip esp32 --port COM10 erase_flash
