Hello everyone,
Once again, I am counting on some sound advice from members of this very helpful forum.
After getting over the hurdle of learning to program Graphic LCDs, I am now stuck at my next big challange: Interfacing a 4-wire resistive touch screen panel over my Graphic LCD.
I have learned how the touch screen works, it seems simple enough. But where things have gotten complicated is how I would connect it to my microcontroller.
Now, I have purchased a ADS7843 and have even paid a lot of money to convert it to DIP. I have read the datasheet, but am puzzled as to why there are so many pins which are not making any sense to me (right now). I tried reading the datasheet but it all seems very puzzling it does not seem to explain things in plain terms.
I need some guidance on how best to interface such a touch-screen to a microcontroller. If using the ADS7843 is the best way, atleast some "plain english" explenation on how this chip works?.
I have seen Youtube videos of what I am trying to achieve (simple touch location recognition), Im sure you all know the feeling when you are stuck but know its possible! Hope someone knowledgeable in this area will show me the way to move forward a bit.
Regards.
