(SOLVED) 2.8" TFT Touch Shield v2 - Capacitive - Tracking Pr

Post by kev042 »

My recently purchased panel is not tracking the x-axis properly when touching in an area when x > ~194. If I start at 204, 0 and move up along the y-axis the panel detects the touch as 320,0. As I continue in a straight line along the y-axis, the panel starts showing the touch points getting closer to where they're supposed to be. But then it starts drawing the line about 10-15 pixels less on the x-axis.

In the attached photo, the yellow, red and blue lines are actually drawn higher than where I was touching. The purple lines are perfect and what I would expect for the entire panel.
