uCOMmandIt GPIO Package for SBC GPio Pins

This module creates an instance of UCI Packet GPIO for a SBC gpio pin. This class does NOT include support for interrupt based input. See UCI-Interrupt package for that.

Set up hardware GPio bus pins as interrupts for use with UCI Interrupt

Enable access to GPios

create (if need be) a gpio group and make sure your user is in the gpio group

change group to gpio for /sys/class/gpio/export and unexport and mode to 770.

make a new udev rules file.

SUBSYSTEM=="gpio*", PROGRAM="/bin/sh -c 'find -L /sys/class/gpio/ -maxdepth 2 -exec chown root:gpio {} \; -exec chmod 770 {} \; || true'"

That should allow access via the on/off package which is a dependency.
