@GetDeviceInfo... I suppose you do some sort of Industrial Automation, using PLCs and stuff... I want to develop a simple touch screen, for school projects... Which would have 4-5 options in the Menus to select, like
add, subtract, divide, multiply...

A really basic one...

@Retched, thanks for the link, I shall look forward to get started on that...
:rolleyes:

Please let me know guys, if you come across anything basic... Meanwhile, i shall let you know if i find one..

P.S. I was seeing this PSoC, the ones that Cypress Semiconductors make.. .Has anyone used it??

I've programmed control of a 4-wire touch screen on a PIC processor. It was pretty easy once I got my mind around the operating sequence.

Guys, I am little bit confused, I can use the features of LCD to program a touch screen right? Basically a touch screen is nothing but an advanced version of LCD correct????

No! LCD is one thing touch screen is another thing. You will need six digital outputs to drive a text LCD more for a graphic one, while you will need two ADC to read and decode the X & Y position from the touch screen.

Oh, ok, so if i have to choose a micro-controller, I should perhaps look for one that has high number of ADC channels, and higher rate of reading those channels right?
