GPIO Switch + sound card

Post by flappix » Thu Jul 19, 2018 6:23 am

Hi @ all,
I want to connect a little switch in addition to the AudioInjector Zero to the GPIO port, like in this example: http://razzpisampler.oreilly.com/ch07.html
Are there any GPIO pins which are safe to use for this?

Would be really if some knows this :)

Yes you can - the card doesn't use many of the pins.

pin 03 : I2C (shared),
pin 05 : I2C (shrared),
pin 12 : Bit clock,
pin 35: LR clock,
pin 38: Data in,
pint 40: Data out

Any of the others will be fine
