I use e2 studio and ssp 1.6.0.i use resistive touch screen.
In my custom board i used SX8650 IC for touch.it was working and i am able to touch.
But when i do pressure then TFT Touch was work other wise not.I also change SX8650 IC resister value but problem not solve.
how i can make touch more sensitive?so i am able to operate TFT Touch smoothly.
Have you made some progress on this one? Were you able to make your TFT touch display operate smoothly?

Hi JB, Thank you for your reply, I am not able to do,can you please help me?
I made one industrial project there was i have require touch smooth.

I'm using the 8650 in my projects now without problems. The thing about that chip (as opposed to the 8654) is that it has no pen up interrupt so you have to simulate that in software. Lacking a pen up would cause UI to act strangely because most UI things are set up to act on the pen up rather than the pen down interrupt.
To use this chip you have to put it into AUTO mode and deal with the extra load that comes from it.
I've attached (I think) the updated version of the driver that works for me..

the portion of the schematic that we're using is this:
It basically just connects directly to the touch overlay. We're using a New Haven display system NHD-4.3-480272EF-ATXL-T
We only use finger to touch with, not pen or fingernail. Which brings a question: you are using a resistive touch overlay, yes? This chip doesn't know about capacitive ones.
