I have been using an older elo touchscreen controller + Surface Wave overlay. The setup worked fine since day one, but now i am having some trouble with it.
It seems that the touchscreen has stopped working (not entirely) on my car computer system. I say not entirely stopped working, because the computer and controller still register the fact that I am touching the overlay, but it's NOT relocating the mouse pointer. In other words, the controller's LED reads OK, the computer beeps when recieving a 'touch', the alignment software even moves to the next target, but the mouse never moves!
The steup works on other systems, and i even formatted and reinsalled the car PC, and the same thing happened!!
System in the works:
Celeron 850 or PIII 933, SB Live! Value into a stock 4 channel amp, ATI vid, 10.4" sharp LCD w/ allen's controller, Elo SW touchscreen overlay and controller, GPS, TV tuner, FW DVD drive, 4 port serial card, and some other stuff....
Loads of ideas.
