What GPIO Python library is known to work with the ALL-H3/5-CC boards?
We are using Raspbian and none seem to work, or complain that they don’t work with that CPU architecture
Please use the proper Linux gpio interface via python3-gpiod. This works across all devices and is the upstream standard.
See examples here: examples « python « bindings - libgpiod/libgpiod.git - C library and tools for interacting with the linux GPIO character device
You can grab the chip and line numbers from our wiring tool lgpio command.
Tried installing, but got:
pi@raspberrypi:~ $ python3 -m pip install -U --user pip gpiod

The error tells you what went wrong. It’s expecting something from lsb_release -a and that command returns a non-zero value. Run lsb_release -a and see what is wrong.
pi@raspberrypi:~ $ lsb_release -a
Traceback (most recent call last):

I tried
pi@raspberrypi:~ $ python3 -m pip install -U --user lsb_release
and got an almost identical error

lsb-release is already the newest version (9.20161125+rpi1).
lsb-release set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Where did you get the image from? It seems there’s some corruption since lsb_release is a basic function that’s supported in all Raspbian versions.

Of course it might be corrupted somehow.
Sounds like reinstall is needed.
The only “work” done to it was another developer getting node.js to work.
Ah, that explains it. Those images are out of date. Please do not use those anymore. Run Ubuntu or port Raspbian from a Raspberry Pi using libretech-raspbian-portability. We will re-release the Raspbian images later next week.
Please let us know with post.
I was just about to reinstall the old image.
We have the beta of the new Raspbian images here: Index of /ci/raspbian/bullseye/
You need to export VENDOR=libre-computer and export BOARD=all-h3-cc-h5 for the wiring tool until we update the bootloader.
