Sleep management(睡眠管理)
显示原文
The MCU can go to sleep when no user input happens. In this case, the
main while(1)
should look like this:
当没有用户输入发生时,MCU 可以进入睡眠状态。在这种情况下,主要的 while(1)
应该是这样的:
while(1) {
/*Normal operation (no sleep) in < 1 sec inactivity*/
if(lv_display_get_inactive_time(NULL) < 1000) {
lv_timer_handler();
}
/*Sleep after 1 sec inactivity*/
else {
timer_stop(); /*Stop the timer where lv_tick_inc() is called*/
sleep(); /*Sleep the MCU*/
}
my_delay_ms(5);
}

You should also add the following lines to your input device read function to signal a wake-up (press, touch or click etc.) has happened:
lv_tick_inc(LV_DEF_REFR_PERIOD); /*Force task execution on wake-up*/
timer_start(); /*Restart the timer where lv_tick_inc() is called*/
lv_timer_handler(); /*Call `lv_timer_handler()` manually to process the wake-up event*/
In addition to lv_display_get_inactive_time()
you can check
lv_anim_count_running()
to see if all animations have finished.
您还应该将以下几行添加到您的输入设备读取功能中,以表示发生了唤醒(按下、触摸或点击等):
lv_tick_inc(LV_DEF_REFR_PERIOD); /*Force task execution on wake-up*/
timer_start(); /*Restart the timer where lv_tick_inc() is called*/
lv_task_handler(); /*Call `lv_task_handler()` manually to process the wake-up event*/
除了 lv_display_get_inactive_time()
之外,你还可以检查 lv_anim_count_running()
以查看是否所有动画都已完成。
