Sample app code to read keypad presses

Durian — Fri, 29 May 2009 00:30:56 GMT

Hi, can someone point me to some sample app code to read the keypad presses on the MX27PDK? Also I am looking for sample app code to write to the LCD driver /dev/fb0.

Thanks

You can use evtest application to read your keyboard keys on MX27PDK.

This package is available in the Savannah LTIB (www.bitshrine.org).

ltib -p evtest.spec -m prep

ltib -p evtest.spec -m scbuild

ltib -p evtest.spec -m scdeploy

- Boot Linux and then (on the MX27PDK prompt):

- Run the evtest application:

evtest /dev/input/event0

Then if you press the keyboard you should see the application displaying the name of the key you pressed.

Regarding your second question: you can simply do a: cat imageraw > /dev/fb0
