这里实现的内容是,在MCU上运行LVGL时,一旦显示完成当前的屏幕页面后,立即创建定时器对象登录后复制timer_meter_speed,这个定时器将会每隔100ms调用一次回调函数登录后复制timer_meter_speed_cb(),在登录后复制timer_meter_speed_cb()函数中,更新变量登录后复制speed的值,然后通过登录后复制lv_meter_set_indicator_value...

实际刷屏调用是通过 lv_timer_handler --> lv_timer_exec(LV_GC_ROOT(_lv_timer_act)) --> timer->timer_cb(timer)--> _lv_disp_refr_timer(lv_timer_t *tmr)
注意,如果使用lv_timer_set_repeat_count=1指定循环1次数,中途打断用lv_timer_reset的话,因为定时器执行结束后会自动删除定时器,lv_timer_reset 无效.此方案不可取. 如果你有更好的方法,请留言. static char sound_src[256]={0};static voidsound_timer_cb(lv_timer_t*timer){lv_timer_pause(timer);if(...
