Hi, I have a S7G2-DK that is being used for development. The included 4.3" resistive touch has been tested and verified. We then based a few GUI designs off of the schematics. A 5.7", 6.5" and 7" design were all done. Testing has shown that the GLCD and GUIX works. The problem lies with the touch screen. All designs use the same included sx8654 driver in SSP 1.3.0. The 4.3" and 5.7" resistive touch work as expected. Then I go to the higher resolution and bigger touch screens and the response time is not good. The specs for the touch screen are basically the same, I have tried changing the Update Hz in the Configuration and that does not appear to help. On the higher resolution, bigger screens, using the fat part of the finger almost gets no response while a stylus gets a quick response. I am trying to understand why there is a difference in touch response and what I options I have. Thank you, Draper
