Simple Calibration page sample

Dear Engineers,

I wonder if there is any example code available with Touchgfx on how to

1) Catch data and compute calibration coefficients?

2) Have a calibration page with the "TouchscreenCalibration.hpp" file functions?

My question has been hard for me to answer since I have not found strong documentation about them. So far I have been able to do so by hand. But I am looking for some automated method.

Your help is really appreciated.
