Timer Handler
显示原文
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
Example:
要处理 LVGL 的任务，您需要以下列方式之一定期调用 lv_timer_handler()：
main() 函数的 while(1)
定时器定期中断（比
lv_tick_inc()优先级低）定期执行操作系统任务
示例：
while(1) {
uint32_t time_till_next = lv_timer_handler();
my_delay_ms(time_till_next);
}

If you want to use lv_timer_handler() in a super-loop, a helper
function lv_timer_handler_run_in_period() is provided to simplify
the porting:
如果要在超级循环中使用 lv_timer_handler() ，则需要帮助程序 lv_timer_handler_run_in_period() 提供功能以简化移植：
while(1) {
...
lv_timer_handler_run_in_period(5); /* run lv_timer_handler() every 5ms */
...
}

Or use the sleep time automatically calculated by LVGL:
或者使用LVGL自动计算的睡眠时间：
while(1) {
...
lv_timer_periodic_handler();
...
}

In an OS environment, you can use it together with the delay or sleep provided by OS to release CPU whenever possible:
在操作系统环境中，您可以将其与操作系统提供的 延迟 或 睡眠 一起使用，以尽可能释放 CPU：
while (1) {
uint32_t time_till_next = lv_timer_handler();
os_delay_ms(time_till_next); /* delay to avoid unnecessary polling */
}
