Sleep managementΒΆ
The MCU can go to sleep when no user input happens. In this case, the main while(1)
should look like this:
while(1) {
/*Normal operation (no sleep) in < 1 sec inactivity*/
if(lv_disp_get_inactive_time(NULL) < 1000) {
lv_task_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_DISP_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*/
In addition to lv_disp_get_inactive_time()
you can check lv_anim_count_running()
to see if all animations have finished.
