I run lv_async_call in child thread, usingxTaskCreatePinnedToCoreinESP32,lv_async_timer_cbseems running twice somtimes for onelv_async_call. Here is my log code inlv_async.c: staticvoidlv_async_timer_cb(lv_timer_t*timer) {printf("### lv_async_timer_cb 1 \n");lv_async_info_t*...
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...
