Or for 2.5.X you could use EVIOCGKEYCODE or EVIOCSKEYCODE using
/dev/eventX. Also the input api supports up to 220 different keys and
could support up to 255. If you app needs to use a large keycode space
then use this instead. Its better to use this interface especially
for embedded systems that have only a serial console, but sometimes
we need to use a regular keyboard. Consider for example a hand held iPAQ.
Usually their is no keyboard attached. Here you have a graphical interface
(using framebuffer) and a touch screen. So here I like to have a kernel
that uses fbdev without the VT console system and input drivers to
interface with the device. Debugging can be done by the serial console.
If I attach a keyboard I like to be able to use it without having to have
a console system needing to be built in. Remember every byte of space
counts. Getting keycode via the console layer should eventually be
replaced by this approach.
