Hey there I have a big problem concerning my ATmega2560!
It use is to controll a big Display for a gym hall.
Therefore its communicates with an raspberry Pi via Uart.
All works fine but after a blackout the ATmega2560 wont start again.
You have to remove the wires from the Uart, so that the ATmega 2560 can start proberly again.
Specs of the Programm: I recive the the Data from the raspberry pi via the rx interrupt routine.
I also use Compermatch Interrupts of other timers.
My question is: Does a blackout work like an reset?
Could it be that the Interrupt routine of the Uart causes the fail start?
