What version of LVGL are you using?

Assuming it’s 8x then in the callback you would use something like:

https://docs.lvgl.io/master/widgets/colorwheel.html#_CPPv421lv_colorwheel_get_rgbP8lv_obj_t

lv_color_t col = lv_colorwheel_get_rgb(obj);

then (based on Colors — LVGL documentation):

uintX_t red = col.red
uintX_t green = col.green
uintX_t blue = col.blue

note X is 8 or 16.

Please note that I havent tested this, I’m just going off the documentation.

In future please include more info in your query. A single line question isnt that helpful.

Thanks! It works with:
uintX_t red = col.ch.red
uintX_t green = col.ch.green
uintX_t blue = col.ch.blue
