Troubleshooting • Re: Busy GPIO's Raspberry PI5

I guess 'flask' with 'debug=True' is doing something like this -

Code:

import gpiozeroimport osimport sysLED = gpiozero.OutputDevice(0)if len(sys.argv) <= 1 or sys.argv[1] != "forked":  os.popen("python3 {} forked".format(sys.argv[0])).read()

That works pre-Bookworm if not using 'libgpiod'. It doesn't with 'Bookworm', using 'libgpiod', and presumably Pi 5.

Arguably it should never have worked, only worked because of what some would describe as flaws in the way GPIO has traditionally been handled on a Pi, which 'libgpiod' no longer allows.

Sooooooooooooooooo... this is the Solution
I have to move on without this argument.
