LVGL needs a system tick to know elapsed time for animations and other tasks. You need to call the lv_tick_inc(tick_period) function periodically and provide the call period in milliseconds. For example, lv_tick_inc(1) when calling every millisecond. lv_tick_inc should be called in a higher priority routine than lv_task_handler() (e.g. in an interrupt) to …
