I need your help!!

    Can someone point me a touch screen monitor that works under
console? I've tried a tsharc (from hampshire) but it doesn't work even
in X. I develop programs under console using framebuffer so i need also
a nice api to make my programs work with touchscreen. I'm trying to use
libgpm, but any other suggestion is welcome.

    I'm using latest kernels (2.6.21) and gentoo :)

    Thanx

Rodrigo Forlin

I bought a Touchscreen from some car-tuning guy on ebay. The touchscreen
is detected as an eGalax compatible unit and works using the
usbtouchscreen-module of the linux-kernel (using 2.6.19-gentoo-?).
Works as in "the cursor moves when I touch it". I had to patch the
kernel to add some sysfs-entries to be able to calibrate it without X.
I sent the patch to the maintainer some days ago, who has not repiled
yet. If anybody is interested in the patch, please ask.

I use pygame with the fbcon SDL-Driver, that works without any problems.
Some rough project overview and screenshots can be found at
http://www.spida.net/projects/pympdtouchgui/, code will follow.

 HTH, if you want more details, feel free to ask.

    Thanks Timo, but I receveid an e-mail from hampshire with a new
driver and this one works. It seems that it is a good product, and they
trying to support linux.

    I'll work a little harder with this one and if this does not succeed
i'll ask your help.

    Thanks again,

Rodrigo Forlin

    With the newer driver the calibration software works under X
perfectly. Under console i can't see the targets. The program asks me to
click on certain coordenates x,y but with the black screen i have no
idea where it is ! :)

    Actually it isn't a driver anymore. It's a daemon that interprets
serial data though serio_raw module and feeds X and console with the
events.

    I emailed hampshire to calibrate it under console (maybe i've not
installed any libs they suppose default to linux distros), and to make
my program event sensitive. I asked them it they have their own api or
any library that interfaces it.

    With their test software i could see that the events are reported
correctly on console. Now i want a cursor and an API.

Hi,

Have you got calibration software running under X or is it working only
in console mode ?

Best Regards
