I'm toying with adding a few hard buttons to the system to allow a user to switch radio streams or toggle between play and pause. Hooking up to the GPIO lines seems like an easy way to accomplish this. Does anyone know from a software perspective if it is possible to access the status of these pins in the Rune kernel or has this been optimized out?
I see and I do have a /sys/class/gpio folder to work with, so maybe all the parts are here. I was just curious if anyone else has been down this path yet.
