| 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. |
