HBOS 64 Alpha 8: Python "No module named 'RPi'" #555

Closed kontaktwackler closed 1 month ago

kontaktwackler commented 1 month ago

Describe the bug I am trying to reuse a python script used to control volume via a rotary encoder. Script was working fine on latest non 64bit hifiberry os version. on 64 alpha 8 the script is not working because this python import command in the script fails: from RPi import GPIO

HiFiBerryOS version 20240523

HiFiBerry sound card DAC+/Amp2

To Reproduce python3: try to import "from RPi import GPIO"

Expected behavior module RPi should be available to be able to control GPIO

You're right. However as the GPIO module uses an old kernel interface that's not available anymore, we can't add this. The code needs to be rewritten.

hifiberry commented 1 month ago

I just noticed that you're using your own script. In this case, you have to rewrite it. Rpi.GPIO isn't supported anymore on the latest Linux kernel.

Thanks for the quick reply. Will check how to rewrite for new kernel.

Have a look at the gpiod module, e.g. here: https://github.com/hifiberry/audiocontrol2/blob/master/ac2/plugins/control/powercontroller.py
