The code for doing the calibration is not trivial, as the display is not linear. That is, moving down 5 and across 4 doesn't necessarily put you on the right cursor. By the time you get to the lower-right quadrant, it's off quite a bit. We had to account for that slop in our code.

Thanks for the quick reply Jack.??
I pretty much expected the board+BOM method, which is fine.? I've done that before. I'm patiently awaiting the availability as I'd love to play with this.? I have an unmodified EARLY uBITX that I've had wonderful results with using an AlexLoop.??
I may purchase BOTH resistive and capacitive and see how they work out.? I think the cap screen should be OK as long as we have a way to tweak the calibration.
