Hej Folks!
I am relatively new to RP, playing around for about 4 weeks now with the RP5. Half a year of experience with Python. So maybe my question is obvious to solve for others, but i have done quite some research / testing and not found any explanation / solution so hopefully some of you can enlighten me.
I am pretty lost on using the GPIO Pins - which i generally love to do.
First getting into GPIO was more difficult then i thought, but after some time i figured out that apparently RPi.GPIO is not working anymore on RP5 as they should do - so people advise to use GPIOZero instead, right? But GPIOZero still needs to have any pin factory as a base for communication. After some struggling i got my first GPIO Scripts working, but then started using virtual environments for some reasons.
And i have not figured out how to access GPIO from venv - and more confusingly the more i tested the less i understand how GPIOZero actually works on RP5.
Using GPIOZero without venv with a stepperMotor works perfectly fine:Execution & Output:It really fascinates me that there seems no gpiozero.pin_factory but its working.
Now the same with venv:Ok, i see, i dont have any pin factory, so i install some (have installed each alone and still did not work):And another problem - basically everytime i use RPi.GPIO, i get the same error:
RuntimeError: Cannot determine SOC peripheral base address
Full response:And lastly pip list:I really dont understand what the problem here. It should not be a rights problem, as the user is the same. But what else? ![:?:]( "Question")

Thanks for any help!
