Hello, I need to control the LED backlit of my EA DOGM128. Whenever the user pushes one of the 6 control buttons it turns on, after some minutes if no interaction happens then the backlit is turned off.
The problem is that when u8g2.userInterfaceSelectionList or u8g2.userInterfaceInputValue are called the main loop looses control over interaction with the user. I've tried using pinChange interrupt on the same pins handled by u8g2 but that makes the code non-working.
How can I append my turn_backlit_ON() routing to u8g2 switches handling?
