When I connected 2 switches to GPIO 23 and 24 (plus 3V3 and GND) the PhatDAC stopped working.
PiMoroni claims that the PhatDAC only uses 3 GPIO pins per this page https://pinout.xyz/pinout/phat_dac
In more detail, I connected Pi Zero W to PhatDAC with extra-long header. passing thru the PhatDAC board.
Jumpers connect the thru pins to my switch board.
Simple switch board has 2 pushbuttons with 10K pulldown resistors.
I want to use GPIO to control VLC audio via python.
The switches and python scripts worked fine using the (awful) PWM audio, but I want better audio.
Does anyone know if one can use a few GPIO pins without messing up the PhatDAC?
