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.
