GINPUT
From uGFX Wiki
GINPUT is a powerful module which provides an easy way to interface different hardware peripherals such as touchscreens to the rest of the library. It provides everything which these peripherals need in order to operate properly such as calibration routines for the touchscreens.
Touchscreen
A touchscreen can be interfaced very easily through the GINPUT module. It doesn't matter if it is a resistive, capacitive or any other touchscreen technology.
