@György-Farkas said in newbie issue with gpioctl not seeing HIGH on Arduino Dock 2:

ATmega chip

That worked, thank you.
However I have an OLED on the expansion header so I would prefer to use the ATmega pins because that is why I bought the Arduino Dock 2 board.

I think I found the direction to flash the ATmega pins, however I don't see a sketch to program it with, or documentation on what commands to use to control those pins.
