TSC2013 Knowledge

Other Parts Discussed in Thread: TSC2013-Q1, TSC2013EVM

Hi,

I want to design in TSC2013 part for resistive touch panel for muti-touch. I have few question, would you help it? Thansk!

1. Does it only one solution for muti-touch controller? Because it seems needed the software effert to do the algorithm.

2. I got the inforamtion from datasheet. "The R(SENSE) resistor value is the lowest panel resistance (X or Y layer) which is approximately 4.5. This resistor value provides the best dynamic range for dual-touch separation."

What's 4.5?

3. Does it need many software effort to do it? Or you have some software resource for help it?

4. Any panel vendor suggetion list? Size concerning?

Sorry for such more question, I am appreciated your helping. Thanks!
