For running this demo properly, please make sure **LV_MEM_SIZE** is at least **38KB** (and **48KB** is recommended):
```c
#define LV_MEME_SIZE (38ul * 1024ul)
```
### Music player ### Music player
The music player demo shows what kind of modern, smartphone-like user interfaces can be created on LVGL. It works the best with display with 480x272 or 272x480 resolution.
