Hi,
I have a few "user interfaces" for a piece of medical kit that I would like to repurpose for use at a local non-profit.
The boxes are ~pentium 90 vintage machines running a *severley* pruned down NT4. Aside from their physical form factor, the big draw for them is the integrated touch panel.
As the boxes are highly integrated (not COTS machines), the touch panel controller is a "special".
Without investing much time, I have been able to locate an EXEcutable that appears to implement the touch panel driver ("mouse emulator"). And, a quick peek inside suggests that it is a resistive overlay. I suspect the driver is actually talking to the A/DC's directly (i.e., there isn't another microcontroller that just handles the touch panel and, perhaps, talks to the main processor via a serial port).
I'm looking for ideas on how to reverse engineer the touch panel interface without a lot of effort (I will need to reimplement it under a different OS). I don't tinker with MS software so I'm pretty clueless as to how to proceed.
I have other touch panel *monitors* available but they are considerably larger and not packaged as nicely as this touch_panel-display-computer.
Thanks!
