Hello,
I am trying to use a membrane keypad that has 5 buttons. It's not a matrix keyboard so I was just going to add 5 buttons into whatever gpio pins I can spare, but I'm having trouble with the overlay file. It says the button needs a "compatible" property, but once I add that it gives me a different error. I've been playing whack-a-mole with errors for a while and not sure what I'm missing.
