Problem with animation from Squareline is dont exported anim object, then you need add line to ui.c or move generated anim to your code…
lv_anim_set_ready_cb(&a, (lv_anim_ready_cb_t)reanim);
get a here is trouble.
func reanim is simple
void reanim()
{
Tpan1_Animation(ui_dot1anim object, 0); //call first stage anim here is only fictive names
}
