0 源码文件还是很多的，先从主函数开始一层层梳理 void et_user_main(void pvParameters) { et_int32 rc = -1; et_int32 num = 0; id_info_t id; /* g_cloud_con_para.auto_relogin = TRUE; g_cloud_con_para.clr_offline_mes = TRUE; g_cloud_con_para.server_addr = ADDRESS; g_cloud_con_para.server_port = PORT;/ os_printf("ET U-SDK var%sn",et_sdk_var()); to_stop_app = 0; id = (id_info_t )malloc(sizeof(id_info_t)); if(id == NULL) { os_printf("et_user_main, malloc id failedn"); return ; } memset(id, 0, sizeof(id_info_t)); if(get_uid(id) != SPI_FLASH_RESULT_OK) { os_printf("et_user_main, get_uid errorn"); free(id); return ; } g_cloud_handle = et_create_context(id->uid, id->appkey, SECRETKEY); if(NULL == g_cloud_handle) os_printf("Init et account failedn"); et_set_callback(g_cloud_handle,et_message_process, et_event_process); rc = et_start_svr(g_cloud_handle); if(rc != 0) { os_printf("et_start_svr failn"); } do { rc = et_login_cloud(g_cloud_handle, g_cloud_con_para); if(rc != 0) { os_printf("login_cloud failn"); } num++; vTaskDelay(num100porttiCK_RATE_MS); }while(rc != 0 && num < 3 && to_stop_app == 0); if(rc == 0) { os_printf("now start init friendn"); init_clients(); // rc = et_get_buddies_online(g_cloud_handle); rc = et_req_buddies_list(g_cloud_handle, LIST_ONLINE); if(rc < 0) os_printf("Get online buddies failedn"); else os_printf("Get online buddies sucessn"); rc = et_sub_allbuddies_state(g_cloud_handle); if(rc < 0) os_printf("Sub all buddies state failedn"); else os_printf("Sub all buddies state sucessn"); } free(id); vTaskDelete(NULL); return ; } 复制代码以上是主函数部分，通篇的os_printf,还有最后的vTaskDelete无不表明了，这涉及到操作系统了 g_cloud_con_para的相关配置，虽然注销掉了，但这可能就是涉及云端的处理部分了但这不是主函数的开始由给出的参考流程可知，在往上还有些初始化才对查找函数调用，确实 /****************************************************************************** * FunctionName : user_esp_platform_check_ip * Description : check whether get ip addr or not * Parameters : none * Returns : none ******************************************************************************/ void ICACHE_FLASH_ATTR user_esp_platform_check_ip(void) { static et_uint32 time = 0; struct ip_info ipconfig; os_timer_disARM(&test_timer); //get ip info of ESP8266 station wifi_get_ip_info(STATION_IF, &ipconfig); if (wifi_station_get_connect_status() == STATION_GOT_IP && ipconfig.ip.addr != 0) { os_printf("got ip !!! rn"); user_set_wifi_led_on(); if (user_main_start_flag == 0) { user_main_start_flag = 1; xTaskCreate(et_user_main, "et_user_main", 512, NULL, 5, NULL); } wifi_reconnect_start_flag = 1; } else { if (wifi_station_get_connect_status() == STATION_WRONG_PASSWORD \|\| wifi_station_get_connect_status() == STATION_NO_AP_FOUND \|\| wifi_station_get_connect_status() == STATION_CONNECT_FAIL) { if ((system_get_time() - time) >= 5000000) { os_printf("connect fail wrong password or ssid wrong!!! rn"); time = system_get_time(); } if (air_kiss_start_flag == 1) { wifi_station_set_reconnect_policy(false); smartconfig_stop(); air_kiss_start_flag = 0; } } //re-arm timer to check ip os_timer_setfn(&test_timer, (os_timer_func_t )user_esp_platform_check_ip, NULL); os_timer_arm(&test_timer, 1000, 0); } } 复制代码果然是更深一层的操作系统部分，定时器设定、wifi状态设定、是否建立应用层主函数 xTaskCreate(et_user_main, "et_user_main", 512, NULL, 5, NULL);调用了之前的那个函数而user_esp_platform_check_ip这个函数也在更上一层的user_init中被调用 /****************************************************************************** * FunctionName : user_init * Description : entry of user application, init user function here * Parameters : none * Returns : none ******************************************************************************/ void user_init(void) { key_gpio_t key; struct station_config config; struct ip_info info; et_uchar result=0; os_printf("now SDK version:%sn", system_get_sdk_version()); if(get_fac_norm_mode(&result) != SPI_FLASH_RESULT_OK) { os_printf("get_fac_norm_mode error, NORMAL moden"); } if(result == FAC_MODE) { os_printf("run in factory moden"); uart_init_new_uart1(BIT_RATE_115200); UART_SetPrintPort(UART1); uart_init_new(BIT_RATE_9600, result); return; } os_printf("run in normal moden"); // show logo user_show_logo(); if (RETURN_OK != user_get_work_mode(&work_mode)) { os_printf("get work mode fail !!!n"); return; } if (RETURN_OK != user_init_work_mode(work_mode, result)) { os_printf("init work mode fail !!!n"); return; } // wifi led control xTaskCreate(user_wifi_led_control, "wifi_led_control", 256, NULL, 2, NULL); //wifi event handle wifi_set_event_handler_cb(et_wifi_event_cb); memset(&key, 0, sizeof(key_gpio_t)); key.key_gpio_pin = AIRKISS_KEY_IO_PIN; key.key_num = AIRKISS_KEY_IO_NUM; airkiss_key_init(&key); wifi_set_opmode(STATION_MODE); wifi_reconnect_start_flag = 0; xTaskCreate(airkiss_key_poll_task, "smartconfig_task", 256, NULL, 2, NULL); memset(&config, 0, sizeof(struct station_config)); if(wifi_station_get_config_default(&config) == true) { os_printf("ssid=%sn", config.ssid); wifi_station_set_config_current(&config); //for static ip set /wifi_station_dhcpc_stop(); IP4_ADDR(&info.ip, 192, 168, 1, 43); IP4_ADDR(&info.gw, 192, 168, 1, 1); IP4_ADDR(&info.netmask, 255, 255, 255, 0); wifi_set_ip_info(STATION_IF, &info);/ } os_timer_disarm(&test_timer); os_timer_setfn(&test_timer, (os_timer_func_t )user_esp_platform_check_ip, NULL); os_timer_arm(&test_timer, 1000, 0); } 复制代码在这一层对当前进度信息包括SDK的版本等不断输出，分别创建任务处理wifi控制led的和按键配置，并且具体的像GPIO的配制、wifi参数的配制、操作系统定时器的设置等底层基础的进行了设置 xTaskCreate(user_wifi_led_control, "wifi_led_control", 256, NULL, 2, NULL); xTaskCreate(airkiss_key_poll_task, "smartconfig_task", 256, NULL, 2, NULL); 而user_init这个函数才是整个用户应用程序的开始，不过再往前的系统初始化部分没找到从user_init这个函数开始，一层层的，按照参考流程把主体函数给拎出来，从而对整体的源码就有了个初步了解 0
