We are designing a small embedded control system and want to use a touch screen interface rather than a keypad interface.... Does anyone know of an add-on and cheap touch screen module (preferably serial controlled) that we can use with out existing LCD module...

thanks in advance,
abhas.

What size are you looking for? We've used ELO and Microtouch for full-size VGA panels. Those are serial. For our smaller quarter-VGA displays, we actually used a grid based touchscreen to save money (all the user does is
punch buttons -- no need for a real mouse).

as i specified in my earlier post - we have a 240x64 pixel LCD - so i'd say that it's pretty small... our purpose is to use the touch screen for pushbuttons - not mouse work or things like that.... so even a grid based low resolution touch screen would do very well...

Take a look at www.InstantHMI.com for a HMI using a Palm via serial port. I haven't tried this unit, but it looks good and we're investigating for a system presently under design.

I'm actually looking for the same item (small touch screen dispay) for a system in research too. Does anyone have any suggestions of companies? I've checked out ELO, but their screens are relatively large. I'm looking for something about the size of a Palm Pilot.
