I used a style animation.
to finish the animation
lv anim_del (&sf, NULL) does not return true.
// Animate the new style
lv_style_anim_init(&sf);
lv_style_anim_set_styles(&sf, &style_roller_anim, &style_roller, &style_roller_bg);
lv_style_anim_set_time(&sf, 500, 500);
lv_style_anim_set_repeat(&sf, 500);
lv_style_anim_create(&sf);
// Delete Anim
if(lv_anim_del(&sf, NULL) == true) {
printf("DEL OK\n");
}
else {
printf("DEL Anim - Erro\n");
}
