: O.K. I have built Microwindows and have enabled the "IPAQ" TS code. I
: modified the ucb1200_ts code to work with my ARM hardware. All of that
: code is working. (I can manipulate the mine game.)

Cool.  BTW, I'm interested in keeping any enhancements/modifications
to kernel touch panel drivers if you'd like to send them. ;-)



: 
: Now I need to calibrate the touch screen. Does any code exist for doing
: that on the ARM platform? The ucb1200_ts code is suppose to have
: Microwin style calibration.

There's a working touch panel calibrator for the linux-vr
style touch screen driver in the Microwindows source that
Brad LaRonde wrote.  It's GPL, so it's in
microwin/src/contrib/GPL/tpcal

Check it out.  I've checked this version against the latest 0.88
sources (patch1)

Regards,

Greg
