Hi,
I want to port the wacom driver for the GP2X portable console. It's a dual
core ARM9 200Mhz linux 2.4 device without X11, only framebuffer. It has USB
host ports avaliable on a breakout board sold separately.
Compiling the kernel module should be easy as the GP2X kernel source is
avaliable. But as X11 is not avaliable I have to implement a way to read the
raw /dev device node.
My question is, how can I interface with the device node? Is there any
document or do I have to browse through all the source code trying to get it
myself?
Can a mouse be emulated? I mean, create a device node /dev/input/mouse that is
a wacom emulating a ps/2 mouse. The reason I want to do this is because there
already are applications and games that support mouse (i.e.quake,
libSDL...and,contradicting what I said before, a kdrive-based X11 server,but
it's not very useful,as it only has xpdf ported) Anyway I also want a way to
the apps to detect sension pressure, tilt...so I also have to develop a
library for the apps to link against it.
What's the best way to do the mouse thing, as a daemon, as a library,
or "hacking" the linuxwacom driver(what I think it's not the best solution) ?
Any ideas?
