solved, I have tried this:
Short 'BAT' with 'GND', then connect USB cable to power on.
and upload the test code of Arduino.
and the screen is working again!
Thank you for your answers
I hope this works for someone else
Hello, good day,
I bought an M5StickC, and everything worked fine the first few days.
I was testing several examples of the arduino ide library, but suddenly the screen stopped working.
I can continue loading code and with the test code I can turn on and off the LED correctly, but the screen always turns black.
Any idea what could happen?
or the screen has died after less than a week of use?
(Just to clarify, he has not received any blow or connected anything to any pin that may have broken inside)
thanks in advance
