How to change the color or transparency of this part in the lv_arc to look like the example made in other app
Hi @Yuri_Alves_Bordin ,
The lv_arc consists of three parts (MAIN, INDICATOR, and KNOB). I am not sure which one you are referring to, but here is an example of how to change the opacity.
lv_obj_set_style_arc_opa(arc, 128, LV_PART_MAIN);
lv_obj_set_style_arc_opa(arc, 255, LV_PART_INDICATOR);
lv_obj_set_style_bg_opa(arc, LV_OPA_TRANSP, LV_PART_KNOB);
