The Gig

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

The Hardware

VGA 17" panel
IR-based touchscreen connected to a custom touchscreen controller based on an Atmel AT91 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
chips are running firmware v1.3, apparently v1.5 exists but is not trivial to find

The Software

Linux-input driver: linux/drivers/input/touchscreen/inexio.c
Xorg xinput driver: http://repo.or.cz/w/xf86-input-inexio.git

Reverse Engineering the Protocol

to be filled in.
