Part Number: TSC2007
my customer used TSC2007 for their resistance touch screen control, they found sometimes the touch location response is not correct, for example, when they touch to MENU icon, but the screen response to HDCP icon(please refer to the attached pictures for reference), when problem happen, it's randomly response to incorrect icon.
Attached is their C code and schematic, please help to review it and give us your advise or comments what would be the problem root cause? Thanks.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

I have reviewed the schematic and It seems right. I think that It could be a noise issue with the analog interface. The connection between touch screen and the TSC is the key for the touch system performance and It should be kept as simple, as short and as secure as possible. Have you checked the noise levels in the analog interface? If the system has noise high levels you can have a look at the next application report: sbaa155a to find further information about as reducing analog input noise.
