a)在上一讲中我们成功完成了micropython的移植工作,但是在使用后发现通过pyb.LED(1).on() 命令控制不了板子上的LED。通过UART(1).write(‘hello’) 也无法操作串口,还报错。这些问题要怎么解决了,本节将以我手中的这个开发板主例带领大家一一解决上面问题。 LED控制问题,在putty窗口给开发板发命令,发现命令执...

--uart-repl-bitrate={baud/bitrate}: This changes the connection speed for the serial connection when using the UART REPL. This is a nice feature to use when transferring large files to the ESP32. The highest speed I have been able to set it to is 921600, you might be able to set it...
