Elo touchscreen under windows

SDL Development
1

Hello,

I’m trying to use an Elo touchscreen in a SDL
program under windows (2000), but the mouse
coordinates in the SDL_MOUSEMOTION event are not
correct. Can SDL use such devices ? Is there a
library to handle that ? I’ve read something about
an elo framebuffer library under Linux, what about
windows ?

thanks a lot

I use an ELO touchscreen on my MP3 jukebox that uses a custom fullscreen
SDL/framebuffer application. At the time I wrote the software (two years
ago) the only ELO drivers I could find were X-Windows and some reference
DOS code. I used the reference code to write my own ‘builtin’ driver
for my application that just talks directly to the serial port connected
to the touchscreen. The calibration code is a bit kludgy, but I am in
the process of cleaning that up. I could share it with you if you
thought it might be useful.
