Task Handler

英文 自動翻訳

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

  • while(1) of main() function
  • timer interrupt periodically (lower priority than 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_timer_handler();
   my_delay_ms(5);
 } 

To learn more about timers visit the Timer section.
