Connecting Touch Screen to BOE REV. A

Chris Drzewiecki

I purchased a touch screen LCD from Simmetry.com and was wondering what the best way to hook it up to the BOE w/ a BS2.· Here's the schematic of the display http://www.simmetry.com/schcs1.asp.
I would say that I would connect J4 to the serial connector with J4-1 to VDD on breadboard, J4-2 to VSS on breadboard, J4-3 to pin 3 on serial port, and J4-4 to pin 2 on serial port.· Is this correct?

Thanks,

Chris

Chris,

I've had my Simmetry touch screen for about two weeks, so I'm hardly an expert.

I am using:

J4-1 Vdd +5 Volts
J4-2 Vss Ground
J4-3 PIN 15 BS2 SERIN
J4-4 PIN 14 BS2 SEROUT
J4-5 PIN 12

Either monitor PIN 12 or SERIN [noparse][[/noparse]WAIT(">")] for command completion. I've done it both ways.

I think that BS2 PIN 16 for SERIN and SEROUT would work on J5 pins, but I have not tried that yet.

So far I have made up my own screens, loaded and saved them, and written a simple four screen menu.

Everything seems to be working very well.
