I have been trying to bring up the GPIO function using the wiringPi version included in Raspian. It is not working. The git referenced in the sparkfun instruction is no longer available. There are many forks available, but which one has reliable software. I am running a raspberry pi 4 model B Rev 1.2.
Are you using this as a reference? https://learn.sparkfun.com/tutorials/ra … troduction
WiringPi isn’t for Python, but do keep in mind that Gordon is no longer supporting WiringPi: http://wiringpi.com/wiringpi-deprecated/
That could be one source of why you might be experiencing issues. Can you share the code you are trying to run?
