I'm using the MAX14830 as UART and GPIO extender. Got the UART working, but I'm confused on how to use the GPIO.

I notice there is a new entry in /sys/class/gpio (gpiochip496):

pi@raspberrypi:/sys/class/gpio $ ls 
export  gpiochip0  gpiochip128 gpiochip496  unexport

pi@raspberrypi:/sys/class/gpio $ cat gpiochip496/label 

But now what? What number does the GPIO have? Is it controllable via commandline and/or in python RPi.GPIO?



Fixed using libgpiod, as explained here: https://www.acmesystems.it/libgpiod
