Due to lack of response, we ended up refactoring and using libgpiod. Thanks.
More info. It wasn't installing at all previously, but now it installs. When I try running GPIO.setup() as a user I get: RuntimeError: No access to /dev/mem. Try running as root! If I run as root, I get: RuntimeError: Mmap of GPIO registers failed
Plans to support Raspberry Pi 5
I tested with the Alpha Release and it seems to be working great. Thanks for updating this.
