Sorry for the inconvenience. Here's the text version:

Or you can download the demo code:

https://forum.elecrow.com/uploads/390/U5CKM34HWAP0.zip

this doesn't compile even with LVGL installed.

#include <demos/lv_demos.h>

compilation terminated.

Hello @miracle ,

You need to copy the lv_examples.h and lv_demos.h in the examples and demo foldersto the lvgl(or lvgl-3)/src directory
