[edit] The Gig

We acquired a bunch of Inexio 17" touchscreen LCD display panels. This page documents what we've learned about them.

[edit] The Hardware

[edit] Display

  • VGA 17" panel, 1280x1024 @ 75 Hz according to EDID

[edit] Touchscreen

  • IR-based touchscreen connected to a custom touchscreen controller ("C-CONTROLLER 2007.04.19 REV 4.94" silkscreened on PCB) based on an Atmel AT91SAM7S64 ARM microcontroller
  • touchscreen data available as RS232 via DB9
  • also apparently the same data is available as a USB CDC ACM device via the USB B-port hidden under the casing
    • however, the USB port doesn't seem to work -- it continually goes like so:

  • chips are running firmware v1.3, apparently v1.5 exists but is not trivial to find
