Introduction
This document captures programming details of FT800 series chips including graphics
commands, widget commands and configurations to control FT800 series chips for
smooth and vibrant screen effects.
The FT800 series chips are graphics controllers with add-on features such as audio
playback and touch capabilities. They consist of a rich set of graphics objects (primitive
and widgets) that can be used for displaying various menus and screen shots for a range
of products including home appliances, toys, industrial machinery, home automation,
elevators, and many more.
1.1
Overview
This document will be useful to understand the command set and demonstrate the ease
