I have given a talk at EuroBSDCon2024 about GPIO, slides are online
and readable, they contain detailed information about how to use
GPIO in RPi3B+ for input and output, gpioirq is covered, there are 
sample circuits.
I made my best to make it beginner friendly.

From my experiments note i can state that on BeagleBone Black i2cscan 
does not work in CURRENT.

I am trying to fix i2cscan myself, but I am a busy beginner, so i am 
very slow;)

Anyway, a lot of info, I will re-read very carefully, thank you
