Re: [OT] Possible bulk buy on 128 by 64 graphic displays with touch screen

Ian,

The full command set can be seen at http://www.simmetry.com/inslit2.asp

You don't need any external electronics to use this ... just a
regulated 5VDC supply and RS232 to send in commands/receive
touchscreen output.

The units ships with a really neat built-in 'touchscreen keypad' data
entry utility. There is also a nice 'rolling demo' mode that comes
pre-supplied and runs on 1st power up of the unit.

All the brains for this display are in the PSoC chip - I suggested a
few ideas to the author (Dave) and he incorporated them in a later
release (he sent me a new PSoC chip).

Both display contrast and brightness can be set via commands sent over
RS232. Don't know if there is a landscape/portrait flip.

A great little unit. I think that anyone would be hard pressed to do
as good a job with an AVR chip as Dave has done with the PSoC.

I do have one spare ... happy to loan this to you if you would like to
play/experiment.

Derek.
