Hello,
I have a touch screen problem. Normally, point 0.0 is located in one of the corners. I find myself around the middle of the display. In the upper half I have negative values and in the bottom positive to about 700.
How can I start the coordinates in one of the corners.
I use pro mini 328 3.3V
