Hello, I am a Beginner.
The LCD on my Core2AWS has stopped lighting up.
The power seems to be on, writing is normal, and when I restore the firmware to its initial state with M5Burner, the LCD lights up again, so it does not seem to be a hardware failure.
After writing the sketch using ArduinoIDE, the LCD will not light up.
I would appreciate any good advice you can give me.
