Part Number: TSC2046
my customer is using TSC2046 for their system to interface with their touch panel.
When they move the pencil on the touch panel quicky(<1s) from left to right, the X position data will be lost for the left 1/3 and right 1/3, only the 1/3 in the middle will be recorded.
If we move the pencil on the touch panel slowly, the X position data will be recorded correctly.
The same applies to Y position.
Since MCU will record the X position and Y position and then draw line on the screen, if we move pencil too fast from left to right, only 1/3 in the middle will be displayed on the screen.
What may be the cause and how could we solve the problem?
Can you please share a schematic, some scope shots of the communication lines (CS, DIN, DOUT, DCLK, etc) and the X and Y lines?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
