Ok,ok, so there is only one mouse device at a time! I see the reference to the mousedev Device only once.
Cause I am new to programming drivers and to programming nano-X, does anybody know a nice (small changes) solution for my problem?
Or is there no nice solution?
Do I really need to program a driver which is capable either to transmit data from the mouse or the touch?
I am sorry for questioning so much.
Nice Weekend anyway!
Peter

Ok, thanks, there was a problem in connecting with the cvs.windows.org, cause our intranet does not allow cvs-protocol (only http!) connections, but I did download it at home.
I have rewritten the code of mou_touchscreen.c so that it loads every time the nxcal.dat from the file system.
Also I have rewritten the code of nxcal transformation with the code of
http://www.embedded.com/shared/printableArticle.jhtml?articleID=164303539 (how to write a touch driver)
And
http://www.embedded.com/story/OEG20020529S0046 (calibration algorithm, which works very well for me)
And now it (almost) works, like it should.
Another interesting question:
Is there any support of nano-X for working parallel with touch and USB mouse, with priority for the mouse, if connected?
As I wanted to compile the GPM (and does GPM support USB mice) together with ADS7846 it was not possible.
How can I work around this?
Regards
Peter

> But how can I turn on/off the mouse pointer if I use mou_toucscreen.c?
The mouse driver doesn't change the need for a GrHideCursor at
the end of nanox/srvmain.c::GsInitialize().
> Calibration with nxcal:
I do not see where nxcal.dat is handled by nano-X! I am using the latest
Nano-X full tar ball v0.91.
Use the CVS sources, I need to release them as 0.92. Nxcal was run
before nano-X by a script, IIRC. I think this is all handled in the
pixil.org source for our PDA operating environment, and the
revised and enhanced window manager. See www.pixil.org for
more details.

Greg
