Task Handler(任务处理器)¶
查看原文
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
The timing is not critical but it should be about 5 milliseconds to keep the system responsive.
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
时间并不重要,但它应该是大约 5 毫秒以保持系统响应。
示例:
while(1) {
lv_timer_handler();
my_delay_ms(5);
}
