@Colin rpi gpio 2.07 library not work with dietpi trixie? In general, they don't work on Bookworm either. The old 2.06 library works on Bulleye.

:smile: Okay so far so good. One notification pipe file from the lgpio Python library itself, created in the working dir at import time. It is documented here, used to be informed about GPIO changes, AFAIU: lg library DietPi users will get this fix with the upcoming release tomorrow or Sunday, or …

Who replaced it ? Official Pi did I think. Did Diet-Pi not also do it ? A few more clues would be useful.

As far as I remember, the official Pi was replaced because the new library controlled the pins in a more modern way or something. Things don't work with Bookworm and Trixie. https://dietpi.com/forum/t/node-red-node-pi-gpio-library/24578

They work fine with Pi-OS. So we need to fine out what is different

I don't know if you looked at the link above.

Yes. The pi nodes can use lgpio so it could/should work

Yes correct AFAIK. And the default script checks for it. But I’ve no idea if the Diet-Pi installs it. ( and generally it’s a bad idea to mix the default script with the Diet-Pi installer - you can but it’s a one way deal so in general don’t).

I am just a user and I can install Dietpi and Node red and that's where my competence ends. I have made several attempts with a fresh installation and what is shown here https://dietpi.com/forum/t/node-red-node-pi-gpio-library/24578 but things work half-heartedly or not at all. I tried that too ht…

I have seen this issue over and over in the forum. Someone says something along the lines of "gpio pins don't work any more" Someone else says what setup do you have? What error messages do you see? A third person says it works for me with lgpio. And there the discussion ends. So I'll happily r…

Im quite social currently, so thought id chip in (and sound clever)

python3-rpi-lgpio

RPi.GPIO (used by the python helper for the Node RED Node) depends on an old library - no longer around in recent RPI OS's, and the shim above is a proxy to the new lib (lgpio), and polyfils the missing lib that RPi.GPIO wants.

(at least thats what I understand)
