ValueError: GP14 in use #2
Description
I tried this project, but at first I got the error "AttributeError: 'module' object has no attribute 'SCK'".
Therefore, I directly specified the pin number on line 15 of read.py like "rdr = mfrc522.MFRC522(board.GP14, board.GP16, board.GP15, board.GP22, board.GP14)".
Then, the following error occurred.
Traceback (most recent call last):
File "", line 54, in
File "", line 15, in do_read
File "mfrc522.py", line 34, in init
ValueError: GP14 in use
How can I fix this?
