开发板:           正点原子F407
rt-thread版本: 3.1.0
开发工具:       MDK5.25
BSP:               stm32f4xx-HAL

作业：

基于 OneNet 的智能家居系统，在 OneNet 上创建应用，能够实现如下功能：
* 通过 OneNet 页面控制灯的开关；
* 家里的温湿度信息实时展示；
* 通过传感器监测，当监测到事件，向云端发送信息；
[ 如果缺少传感器硬件，自己考虑以其他方式替代]

* 其他功能自由发挥；
**1 准备工作****1.1 开启 Paho MQTT 软件包**打开 env 工具输入 menuconfig 按照下面的路径开启 Paho MQTT 软件包 RT-Thread online packages    IoT - internet of things  --->        Paho MQTT: Eclipse Paho MQTT C/C++ client for Embedded platforms  --->
进入 Paho MQTT 软件包的配置菜单按下图所示配置![FastAdmin](http://ci.rt-thread.com/3488/site/tutorial/network/mqtt/figures/mqtt1.png)**检查是否配置成功**系统运行起来后，在 msh 命令行下输入 mq_start 命令即可让示例代码运行。msh> mq_start

**1.2开启 onenet 软件包**打开 env 工具输入 menuconfig 按照下面的路径开启 onenet 软件包RT-Thread online packages    IoT - internet of things  --->       
 OneNET: China Mobile OneNet cloud SDK for RT-Thread
进入 onenet 软件包的配置菜单按下图所示配置，里面的信息依据自己的产品和设备的**实际情况**填写![捕获.JPG](/uploads/201808/16/222717idkzka3o394a49a4.jpg)** **检查是否配置成功****系统运行起来后，首先在 msh 命令行下输入 onenet_mqtt_init 命令初始化 mqtt 客户端，然后输入onenet_upload_cycle 命令运行 OneNET 示例代码 。![捕获.JPG](/uploads/201808/16/223149o682xx5zyc776v97.jpg)1.3 onenet端配置请看[https://open.iot.10086.cn/doc/art398.html#97](https://open.iot.10086.cn/doc/art398.html#97)![捕获.JPG](/uploads/201808/16/224405ztrtvdfd5vrjfjcc.jpg)2完成上传数据采集和接受数据解析2.1数据上传,cpu温度和使用率```static void onenet_upload_entry(void *parameter)
{
    double value = 0;
    rt_uint8_t  major = 0, minor= 0;
    while (1)
    {
        value = Get_Temprate() / 100;
        
        if (onenet_http_upload_digit("temperature", value) < 0)
        {
            log_e("upload has an error, stop uploading");
            break;
        }
        
        cpu_usage_get(&major, &minor);
        if (onenet_http_upload_digit("percentage", major) < 0)
        {
            log_e("upload has an error, stop uploading");
            break;
        }

rt_thread_delay(rt_tick_from_millisecond(5 * 1000));
    }
}```2.2 数据解析,开启关闭led```/* onenet mqtt command response callback function */
static void onenet_cmd_rsp_cb(uint8_t *recv_data, size_t recv_size, uint8_t **resp_data, size_t *resp_size)
{
    char res_buf[] = { "cmd is received!<br>" };

log_d("recv data is %.*s<br>", recv_size, recv_data);
    if(0 == strncmp(recv_data, "led", strlen("led")))
    {
        if(0 == strncmp(recv_data + 4, "on", strlen("on")))
        {
            rt_pin_mode(22, PIN_MODE_OUTPUT);
            rt_pin_write(22, 0);
        }
        if(0 == strncmp(recv_data +4 , "off", strlen("off")))
        {
            rt_pin_mode(22, PIN_MODE_OUTPUT);
            rt_pin_write(22, 1);
        }
    }

/* user have to malloc memory for response data */
    *resp_data = (uint8_t *) ONENET_MALLOC(strlen(res_buf));

strncpy(*resp_data, res_buf, strlen(res_buf));

*resp_size = strlen(res_buf);
}
```3 TTS语音合成3.1 云端创建语音应用文档请看[https://ai.baidu.com/docs#/Begin/top](https://ai.baidu.com/docs#/Begin/top)![捕获.JPG](/uploads/201808/16/224701cdxdde18xoiizx3i.jpg)3.2增加text2audio命令行指令```static int baidu_text2audio(rt_uint8_t *text, rt_uint8_t *filename)
{
    rt_uint8_t *url = rt_malloc(URL_SIZE);
    rt_snprintf(url, URL_SIZE, "http://tsn.baidu.com/text2audio?lan=zh&ctp=1&cuid=abcdxxx&tok=24.d753b7aaa592a7aaf881d973b5c888d9.2592000.1536941581.282335-11682789&tex=%s&vol=9&per=0&spd=5&pit=5&aue=3", urlencode(urlencode(text)));
    rt_kprintf(url);
    return webclient_get_file(url, filename);
}

int text2audio(int argc, rt_uint8_t **argv)
{
    if(argc != 3)
    {
        rt_kprintf("usage: text2audio text audio_filename!");
        return -1;
    }
    return baidu_text2audio(argv[1], argv[2]);
}

MSH_CMD_EXPORT(text2audio, Baidu cloud text to audio);```
