Hi all,
I'm using the color touchscreen display and am making good progress. When I look at the raw numbers of touch point coordinates, they clearly have no relationship to the underlying pixel coordinate. I've looked through the threads on this forum, and at least one thread referred to calibrating the touchscreen so the top left and bottom right values are known. I've tried doing this with the tip of a retracted ball point pen and the values seem to vary quite widely even when I'm within a millimeter or so of my last touch. Is there any trick, or are there set numbers?
Thanks.
Ed
