Hi,
In the thread I referred to, the GPIO pins in my case were imposed by
the board I was using (which is a DAC with included power switch
capabilities), so in PcP "tweaks" I had to set the GPIO pins with
respect to hardware configuration. Previous posts in the same threads
mention different GPIO pins. It depends on your wiring...
for your on/off switch, you have to chose pins:
- that are configurable (i.e. not a fixed ground or 5V pin!)
- that are not used by another function e.g. for sound
-
See pinout: https://www.raspberrypi.org/documentation/usage/gpio/
GPIO 17 and 22 are OK but they are not the only ones... I think the PcP
on/off functions work very well, you should get it to work quickly.
