Touchscreen Calibration
I have a PyPortal Titanio and I am programming the touchscreen. I have a number of buttons on the screen which work perfectly, however, I placed a button on the upper right portion of the screen (when in landscape mode) and was unable to capture the button click. When debugging the click, it appears that even though the button is placed correctly by the programmed coordinates, the coordinates returned when attempting a click are inaccurate. This seems to be the only location on the entire screen with this issue since nearly the entire screen is covered in buttons, and all the others work perfectly. How can I overcome this issue?

Re: Touchscreen Calibration
CGrover has a calibration library that might be useful. It's for built-in or featherwing TFT displays. If you look at the example image on his GitHub he's using a PyPortal Titano. ;)
