Good day
I have the NRF_desktop keyboard application running on the NRF52840 Dongle, Zephyr 2.6.1. I would like to us the nrf52840 ProMicro as it has a battery charger build in. I have modified rows and columns accordingly. All my buttons are working except P1.00. I can use any other pin for col 2 and it will work but for some reason not P1.00. It does not appear to be used anywhere else, and I don't get any warnings. Below is my Button_def.h and App.overlay files. I do need to use P1.00 as its the Keypad membrane header col 2.
Any suggestions would be welcomed. Thanks in advance
