GUI library

The GUI library provides a general GUI object and a set of elements to design and operate a human machine interface.

It manages touch and haptic feed-back as well.


Because the GUI library uses the fast update mode, it requires a screen of type Screen_EPD_EXT3_Fast provided by the PDLS_EXT3_Advanced_Fast or PDLS_EXT3_Advanced_Touch libraries.

Some elements use items, a structure that combines an index and a label.
