I have a raspberry pi 5, but unfortunately this isn't working. The official waveshare wiki states, that the raspberry pi 5 need to use a different GPIO library (namely: Install lg library (Recommended for Pi5, BCM library currently does not support Pi5)). Could anyone provide support for this. Or maybe help on what I need to modify to work with it?
Here is the error message i get:

I found a very useful piece of software: GPIOconverter
Using this, and rewriting a few lines in drivers_base.py I was able to get it working on pi 5.
@BTomiii , can you post your modified code in this thread for future reference? There's apparently a conga-line of developers having similar issues with GPIO on the Pi5
@Vansick1 I made a branch and pull request already. You can follow the instructions there.
@BTomiii Thank you so much!
@Vansick1 , let me know if you got it working, or want any help.
