LVGL 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.
