Hello! I need to use pin D10 (P0_21) as GPIO. The datasheet (https://github.com/redbear/nRF5x/blob/master/nRF52832/datasheet/MB-N2_Datasheet.pdf) says it can be used as both reset and GPIO. However, I am unable to configure it as GPIO.
I tried using internal pullups in my arduino code:
But this didn’t change anything.
Any help is appreciated, thanks!!
