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 MAX14830
But now what? What number does the GPIO have? Is it controllable via commandline and/or in python RPi.GPIO?
