nRF52 Micropython P0.00

[wrickert]

Good afternoon,
I made a micropython conference badge using the BMD-340 module. This is an nRF52840 and I am using a slightly modified PC10056 board code. Due to time constraints, I was not able to fully test before I ordered full quantity. I am using P0.00 for a button input and it is too late to change the pin assignments.

I can

Code: Select all

button = Pin(Pin.board.P0,Pin.IN,Pin.PULL_UP)

but button.value() is always 0

Any advice to fix this?

Does your board also have the 32kHz crystal on this pin?

I don't have an NRF52840 board with P0.00 exposed to test this myself, but are you able to read digital values on any other pins?

Is it possible to get a multimeter onto the trace with the button on it to confirm that it is actually changing voltage?
