Hi sir, i was trying to implement your code to start practicing the multi-threading using Sipeed maixduino,
First I tried to customize the firmware and added the _thread the module and burn it to flash.
The problematic is that i get nothing displayed on the LCD and the code finishes execution ( doesn't hold on while loop).
can I get any help about that ?
