How to get motor controller board to work with Pi 5?

[Starman7312]

I recently got a pi 5, with AI kit - hoping to use the kit with it to create an AI powered robot. However the motor controller board won’t work. It doesn’t even power up? No lights at all on top (it does still work with pi 4B).

I’m aware that the GPIO pins have been redesigned for pi 5, and are no longer run on chip - however their orientation stayed the same so can this work and if so how?

I tried running robot code and get multiple errors, such as: “warning (from warnings module) : File /us/Lib/python3/dist-packages/gpiozero/devices.py", Line 300 warnings warni PinFactoryFallback: Falling back from Igpio: [Errno 2] No such file or directory

I would appreciate help on how to get it to work with Pi 5. Thanks in advance, Henry 😎

Sorry for the delay. I have been looking at this issue and believe I know the issue and how to fix it. I will respond with the solution very soon.

Thanks @GeekyTim, please keep me posted

I found a similar issue with a different HAT on the Pi 5 when I was using a virtual environment, but not allowing the venv to access the GPIO libraries required by GPIO Zero.

So this issue may depend on if you are using a virtual environment or not, and which version of the OS you are using.

Try creating a venv with:

python3 -m venv CamJam3-venv

And installing libraries with:

./CamJam3-venv/bin/python -m pip install gpiozero ./CamJam3-venv/bin/python -m pip install lgpio

Let me know how that goes. I've not got a spare Pi 5 with accessible GPIO available at the moment.
