Hi,
I think you are using linux kernel so build the Device Drivers ---> Input
device support --->Mouse interface and specify screen resolution with that
driver. Use "/dev/mice" interface created by this interface.
Because on "/dev/input/event0" provide the raw data and not calibrated.
For the keypad you have to write driver like scan_kbd.c to read from
""/dev/input/event0" or "/dev/input/event1" where your keyboard is attached.
Thanks,
Vinod
