micropython为ESP32-C3添加USB和JTAG支持 [复制链接]

 

为 ESP32-C3添加USB/JTAG支持。使用USB作为编程和终端接口，不使用UART。

 

Add a new board type for ESP32-C3 revision 3 and up that implement the USB serial/JTAG port on pin 18 and 19.  This variant uses the USB serial for programming and console, leaving the UART free.

• Pins 18 and 19 are correctly reserved for this variant.  Also pins 14-17 are reserved for flash for any ESP32-C3 so they can't be reconfigured anymore to crash the system.
• Added usb_serial_jtag.c and .h to implement this interface.
• Interface was tested to work correctly together with webrepl.
• Interface was tested to work correctly when sending and receiving large files with ampy.
• Disconnecting terminal or USB will not hang the system when it's trying to print.

ESP32-C3 这个功能很好，uart0就空出来使用了。这样有两个串口。

我以为可以用JTAG调试mpy程序了，真要这样真是一个很大的促进。

应该是不能直接调试mpy程序，但可以调试c程序吧。
