(Core2 AWS) LCD does not light up



  • 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.

  • Hello @hiranobu

    have you tried a simple sketch like this one? Does that work?

    Thanks
    Felix



  • Have you made sure that you are restoring Core2 firmware and not core firmware.
