I've tried to dim brightness of an led screen when there is an inactivity using a timer. I've used ESP32TimerInterrupt library from Khoi Hoang i've tried to input timer 0,1,2,3 like this ESP32Timer ITimer(1);

afterITimer.attachInterruptInterval(HW_TIMER_INTERVAL_MS * 1000, TimerHandler) gfx->begin(); The lcd screen is not turing on and throws error. Guru Meditation Error: Core 1 panic'ed (IllegalInstruction). Exception was unhandled.

RGB seems also use timer, try avoid the conflicts.
