Changed install and driver files to use pigpio instead of wiringPi on the current Raspberry Pi hardware layer.

Neither the pull request nor the commit message answers the question: Why? :thinking:

There's no supported fork of wiringPi anymore.

WiringPi is dead since 2019: https://web.archive.org/web/20210126203355/http://wiringpi.com/wiringpi-deprecated/ The community tried to keep it alive but it is a dead-end job. Time to move on. Pigpio is the officially recommended library from Raspberry Pi to deal with GPIO pins in C.

Okay get it. Thanks for the explanation. 🙂

However: Why not standard libgpiod from the Linux kernel project like everybody else in the embedded world uses? Does Raspberry Pi have special needs which libgpiod can not cover? 🤔

Ease of use, speed, PWM, etc...
