GPIO support outdated for RPI5 #214

Open jOcK0CkO opened 10 months ago

jOcK0CkO commented 10 months ago

Environment -Device: Raspberry Pi 5

Describe the bug As Pi5 machines have a new architectures, pigpio library is no more in use on those machines, so the chataigne's GPIO module isn't recognizing the device anymore. It seems now, the library handling GPIO is libgpiod.

Additional context Here are the threads talking about pigpio and Pi5: https://github.com/joan2937/pigpio/issues/586 https://github.com/joan2937/pigpio/issues/589

Here is the libgpio documentation: https://libgpiod.readthedocs.io/en/latest/index.html

And here is the RP1 documentation (which seems to be the new hardware processing GPIO on Pi5): https://datasheets.raspberrypi.com/rp1/rp1-peripherals.pdf
