LittlevGL Basic Sample

Overview

This sample application displays “Hello World” in the center of the screen and a counter at the bottom which increments every second. If an input driver is supported, such as the touch panel controller on mimxrt10{50,60,64}_evk boards, “Hello World” is enclosed in a button that changes to the toggled state when touched.

Requirements

Display shield and a board which provides a configuration for Arduino connectors, for example:

or a simulated display environment in a native Posix application:

or
