I set up my Pi Zero Pirate Radio kit some months ago as an AirPlay speaker and all was well, except I found that the buttons on the PhatBEAT hat didn’t work. I’ve finally sat down today to try and understand why it’s not working but realised I don’t have a clue where to begin.
So… where to begin? How can I test whether it’s a software or hardware issue?
(I’m happy to accept that my terrible soldering might have damaged something, but I’d probably have expected to have killed the board entirely, not just stop the buttons from working…)
