Task Handler

To handle the tasks of LVGL you need to call lv_task_handler() periodically in one of the followings:

  • while(1) of main() function

  • timer interrupt periodically (low priority then lv_tick_inc())

  • an OS task periodically

The timing is not critical but it should be about 5 milliseconds to keep the system responsive.

Example:

while(1) {
  lv_task_handler();
  my_delay_ms(5);
}
