Run LVGL built-in demos.
Overview
********
A sample showcasing upstream LVGL demos.
* Music
The music player demo shows what kind of modern, smartphone-like user interfaces can be created on LVGL.
* Benchmark
The benchmark demo tests the performance in various cases. For example rectangle, border, shadow, text, image blending, image transformation, blending modes, etc.
* Stress
A stress test for LVGL. It contains a lot of object creation, deletion, animations, styles usage, and so on. It can be used if there is any memory corruption during heavy usage or any memory leaks.
* Widgets
Shows how the widgets look like out of the box using the built-in material theme.
Requirements
************
* A board with display, ideally with 480x272 resolution or higher.
