Hardware button access in qtopia

[sar_van81]

Hi everyone,

I have a ARM based GPS development board with some hardware buttons. i need to write an application in qtopia core such that when the hardware buttons are pressed, i need to show the application. Can anyone say me how ? To my knowledge, Qtopia cant directly use the board's hardware resource. It can only access through a device driver.for example, inorder to use mouse or keyboard in qtopia, the qtopia opens the corresponding port (/dev/input/event0 or /dev/input/mice). But this hardware button don't have any driver. I checked with the device driver team and they are saying that, the key only generates an IRQ and it dont have any device driver .

can anyone say me any suggestions to do this ?

Well... You need a driver then.
