Best way to use gpiozero #34

Closed pirateradiohack closed 11 months ago

Hello,

I use some additional hardware to control the volume, next / previous, on / off actions. See

https://shop.pimoroni.com/products/onoff-shim?variant=41102600138 https://shop.pimoroni.com/products/raspio-analog-zero

I am comfortable controlling those with gpiozero : https://gpiozero.readthedocs.io/en/latest/

What would be the best way to install gpiozero on myMPDos ?

All I can do is installing some alpine packages by listing them in the bootstrap.txt, but gpiozero recommends installing through pip (the python package manager).

I tried installing pip on a running myMPDos but it did not work. I guess because of the in ram system. The error is no space left on the device, which makes sense. So, before fiddling more in the wrong direction, is there a recommended way ?

Thanks

I can not recommend any way. The maximum size of the root filesystem is limited by the amount of ram your raspberry have. Because of this limitation: install only the minimum of required packages or install the packages into a subdir of /media/mmcblk0p2.

myMPDos integrates myGPIOd that uses libgpiod. I use it to run script on button press. The functionality is at the moment rather limited, but it could be extended.

Thanks.

I have considered myGPIOd. But I would need more features. Like long presses and volume knob.

I think in the meantime I will try to install myMPD on a classic RaspberryPi OS which comes bundled with gpiozero.

This should work without problems. I would recommend DietPi, it ships myMPD.

If you like, you can open issues with features for myGPIOd in the myGPIOd repository.
