Help with FIDO2 user presence setup on STM32L432KC board #20
Description
I am working on integrating FIDO2 functionality on an STM32L432KC (Nucleo) board using your canokey-stm32 repository. I want to implement user presence (UP) detection(using a button or a touch sensor)
Could you please guide me on:
Which GPIO pins are used or recommended for the user presence input on STM32L432?
If I want to connect a capacitive touch or push button, where should it be connected?
Any configuration changes needed in the FIDO2 code to enable UP detection?
