HI All,

I need to write a driver for the keys and
then use the GPIO for interfacing them. My board is AT91SAM9261..
My pins AT91_PA13,14,15,16, 20, 22,23,24,25..
Now I have two questions.
1. can the GPIO pins can trigger the interrupts? so that i can make My driver interrupt driven.
2.Can anybody please provide a step wise procedure for developing that driver and using it to drive the keys connected to it?
any sample code would be greatly appreciated.

Thanks and regards
Ravi Kulkarni
