i have a pi4 (debian buster) with a few .sh scripts for my gpio.
i have installed wiringpi 2.50 and could not read the gpio.
when i install the latest wiringpi 2.5.2 i can read gpio,
but my pifidacplus not working anymore.
if i downgrade to wiringpi 2.5.0 my pifidacplus works but i couldnt read gpio ...
is there a way to read and handle gpio and keep my pifidac alive ?
maybe a diffrent language (python, c, ...) ?
or can i use a alternativ to wiringpi to read gpio in shell ?
dmesg after install wiringpi 2.5.2
