Below is a copy of the cody.py output:
code.py output: Traceback (most recent call last): File “code.py”, line 8, in <module> ValueError: SCK in use

I have read and understood “SCK in use error on feather m4 express #1088” and “nrf: implement checking for pin in use #1089”, which are referenced below. As far as I know, only 1 spi pin is in use.
I apologize if this isn’t the correct avenue for discussion. I understand if I am redirected to a more suitable channel.
