I am using a Bluepill and the 2.4 TFT UNO shield , the samples work from the MCUFriend library.Program with ST-LINK Programmer.
Two functions is not working:
1: The touch sketch does not respond to any pressure on the screen.
2:The serial monitor does not display anything , the port is available and the serial monitor opens .
When I reprogram the Bluepill with Blink and add a Serial print the Monitor does display .
Thanks for any advice.
