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????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.
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?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.
Cheers
Alberto
