If you intend to use `lv_timer_handler()` in a super-loop, a helper function`lv_run_timer_handler_in_period(__ms)` is provided to simplify the porting:
```c
while(1) {
...
lv_timer_handler_run_period(5); /* run lv_timer_handler() every 5ms */
...
}
```
In OS environment, you can use it together with the delay or sleep provided by OS:
```c
while (1) {
lv_timer_handler_run_in_period(5); /* run lv_timer_handler() every 5ms */
sleep(5); /* sleep 5ms */
}
```
