## 概述
|
||||
I2C(Inter Integrated Circuit)总线是由Philips公司开发的一种简单、双向二线制同步串行总线。
|
||||
I2C以主从方式工作，通常有一个主设备和一个或者多个从设备，主从设备通过SDA(SerialData)串行数据线以及SCL(SerialClock)串行时钟线两根线相连，如图1 所示。
|
||||
I2C数据的传输必须以一个起始信号作为开始条件，以一个结束信号作为传输的停止条件。数据传输以字节为单位，高位在前，逐个bit进行传输。
|
||||
I2C总线上的每一个设备都可以作为主设备或者从设备，而且每一个设备都会对应一个唯一的地址，当主设备需要和某一个从设备通信时，通过广播的方式，将从设备地址写到总线上，如果某个从设备符合此地址，将会发出应答信号，建立传输。
|
||||
I2C接口定义了完成I2C传输的通用方法集合，包括：
|
||||
I2C控制器管理: 打开或关闭I2C控制器
|
||||
I2C消息传输：通过消息传输结构体数组进行自定义传输
|
||||
|
||||
## 接口说明
|
||||
1. I2C初始化函数:unsigned int IoTI2cInit(unsigned int id, unsigned int baudrate)
|
||||
参数说明:
|
||||
id: 对应的I2C号
|
||||
baudrate: I2C通信速率
|
||||
return: IOT_SUCCESS表示初始化成功
|
||||
|
||||
2. I2C去初始化函数:unsigned int IoTI2cDeinit(unsigned int id)
|
||||
参数说明:
|
||||
id: 对应的I2C号
|
||||
return: IOT_SUCCESS表示去除初始化成功
|
||||
|
||||
3. I2C写数据函数:unsigned int IoTI2cWrite(unsigned int id, unsigned short deviceAddr, const unsigned char *data, unsigned int dataLen)
|
||||
参数说明:
|
||||
id: 对应的I2C号
|
||||
deviceAddr: I2C设备地址
|
||||
data: 写入的数据缓冲区地址
|
||||
dataLen: 写入的数据字节数
|
||||
return: IOT_SUCCESS表示写入成功
|
||||
|
||||
4. I2C读数据函数:unsigned int IoTI2cRead(unsigned int id, unsigned short deviceAddr, unsigned char *data, unsigned int dataLen)
|
||||
参数说明:
|
||||
id: 对应的I2C号
|
||||
deviceAddr: I2C设备地址
|
||||
data: 读取数据缓冲区地址
|
||||
dataLen: 读取的字节数
|
||||
return: IOT_SUCCESS表示读取成功
|
||||
|
||||
5. I2C速率设置函数:unsigned int IoTI2cSetBaudrate(unsigned int id, unsigned int baudrate)
|
||||
参数说明:
|
||||
id: 对应的I2C号
|
||||
baudrate: 设置的I2C速率值
|
||||
|
||||
## 例程原理简介
|
||||
本例程通过I2C接口函数，与oled点阵屏进行通信，进行oled的相关显示实验

# Niobe开发板MQTT联网演示
|
||||
|
||||
本案例程序将演示怎么在拓维Niobe WiFi IoT Core开发板上编写一个连接MQTT服务器的业务程序，实现开发板联网上报数据到服务器。
|
||||
|
||||
## 简述
|
||||
MQTT（Message Queuing Telemetry Transport，消息队列遥测传输协议），是一种基于发布/订阅（publish/subscribe）模式的"轻量级"通讯协议，该协议构建于TCP/IP协议上，由IBM在1999年发布。MQTT最大优点在于，可以以极少的代码和有限的带宽，为连接远程设备提供实时可靠的消息服务。作为一种低开销、低带宽占用的即时通讯协议，使其在物联网、小型设备、移动应用等方面有较广泛的应用。
|
||||
|
||||
MQTT是一个基于客户端-服务器的消息发布/订阅传输协议。MQTT协议是轻量、简单、开放和易于实现的，这些特点使它适用范围非常广泛。在很多情况下，包括受限的环境中，如：机器与机器（M2M）通信和物联网（IoT）。其在，通过卫星链路通信传感器、偶尔拨号的医疗设备、智能家居、及一些小型化设备中已广泛使用。
|
||||
|
||||
## MQTT协议中的方法
|
||||
MQTT协议中定义了一些方法(也被称为动作)，来于表示对确定资源所进行操作。这个资源可以代表预先存在的数据或动态生成数据，这取决于服务器的实现。通常来说，资源指服务器上的文件或输出。主要方法有：
|
||||
|
||||
- Connect。等待与服务器建立连接。
|
||||
- Disconnect。等待MQTT客户端完成所做的工作，并与服务器断开TCP/IP会话。
|
||||
- Subscribe。等待完成订阅。
|
||||
- UnSubscribe。等待服务器取消客户端的一个或多个topics订阅。
|
||||
- Publish。MQTT客户端发送消息请求，发送完成后返回。
|
||||
|
||||
## 特点
|
||||
- 开放消息协议，简单易实现
|
||||
- 发布订阅模式，一对多消息发布
|
||||
- 基于TCP/IP网络连接,提供有序，无损，双向连接。
|
||||
- 1字节固定报头，2字节心跳报文，最小化传输开销和协议交换，有效减少网络流量。
|
||||
- 消息QoS支持，可靠传输保证
|
||||
- “最多一次”，尽操作环境所能提供的最大努力分发消息。消息可能会丢失。例如，这个等级可用于环境传感器数据，单次的数据丢失没关系，因为不久之后会再次发送。
|
||||
- “至少一次”，保证消息可以到达，但是可能会重复。
|
||||
- “仅一次”，保证消息只到达一次。例如，这个等级可用在一个计费系统中，这里如果消息重复或丢失会导致不正确的收费。
|
||||
- 异常连接断开发生时，能通知到相关各方。
|
||||

## 软件设计

|
||||
**主要代码分析**
|
||||
|
||||
```c
|
||||
static void MQTTDemoTask(void)
|
||||
{
|
||||
// 连接WIFI
|
||||
WifiConnect(SELECT_WIFI_SSID, SELECT_WIFI_PASSWORD);
|
||||
printf("Starting ...\n");
|
||||
int rc, count = 0;
|
||||
MQTTClient client;
|
||||
|
||||
// 初始化网络参数
|
||||
NetworkInit(&network);
|
||||
printf("NetworkConnect ...\n");
|
||||
begin:
|
||||
// 连接服务器网络
|
||||
NetworkConnect(&network, "123.60.8.120", 1883);
|
||||
printf("MQTTClientInit ...\n");
|
||||
// 初始化客户端
|
||||
MQTTClientInit(&client, &network, 2000, sendBuf, sizeof(sendBuf), readBuf, sizeof(readBuf));
|
||||
|
||||
// 连接参数
|
||||
MQTTPacket_connectData data = MQTTPacket_connectData_initializer;
|
||||
// 客户ID，唯一
|
||||
data.clientID.cstring= "Talkweb";
|
||||
// 不使用临终遗言
|
||||
data.willFlag = 0;
|
||||
// MQTT版本号
|
||||
data.MQTTVersion = 3;
|
||||
// 保存存活时间
|
||||
data.keepAliveInterval = 0;
|
||||
// 重新连接后是否清除以前的信息 0表示不清除，1表示重连清除
|
||||
data.cleansession = 1;
|
||||
// 服务器用户名
|
||||
data.username.cstring = "Talkweb";
|
||||
// 服务器用户密码
|
||||
data.password.cstring = "Talkweb1996";
|
||||
|
||||
printf("MQTTConnect ...\n");
|
||||
// 登录服务器
|
||||
rc = MQTTConnect(&client, &data);
|
||||
// 失败处理
|
||||
if (rc != 0) {
|
||||
printf("MQTTConnect: %d\n", rc);
|
||||
NetworkDisconnect(&network);
|
||||
MQTTDisconnect(&client);
|
||||
osDelay(200);
|
||||
goto begin;
|
||||
}
|
||||
|
||||
printf("MQTTSubscribe ...\n");
|
||||
// 订阅主题，并绑定回调函数处理接收到的消息
|
||||
rc = MQTTSubscribe(&client, "pubtopic", 2, MessageArrived);
|
||||
// 订阅失败处理
|
||||
if (rc != 0) {
|
||||
printf("MQTTSubscribe: %d\n", rc);
|
||||
osDelay(200);
|
||||
goto begin;
|
||||
}
|
||||
while (count++) {
|
||||
MQTTMessage message;
|
||||
// 发布的内容
|
||||
char payload[] = {"{\"name\": \"Talkweb\",\"url\": \"https://www.talkweb.com.cn/\"}"};
|
||||
// 仅一次
|
||||
message.qos = 2;
|
||||
message.retained = 0;
|
||||
message.payload = payload;
|
||||
message.payloadlen = strlen(payload);
|
||||
// 发布
|
||||
if ((rc = MQTTPublish(&client, "pubtopic", &message)) != 0) {
|

printf("Return code from MQTT publish is %d\n", rc);
|

NetworkDisconnect(&network);
|
||||
MQTTDisconnect(&client);
|
||||
goto begin;
|
||||
}
|
||||
osDelay(100);
|
||||
}
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
## 编译调试
|
||||
|
||||
### 修改对接热点的账号密码
|
||||
|
||||
修改`mqtt_main.h`第32行和33行的WiFi热点SSID和密码，改成自己环境中的WiFi热点。
|
||||
|
||||
```
|
||||
// 默认WiFi名和密码
|
||||
#define SELECT_WIFI_SSID "111"
|
||||
#define SELECT_WIFI_PASSWORD "0987654321"
|
||||
```
|
||||
|
||||
### 修改 BUILD.gn 文件
|
||||
|
||||
修改 `applications/app/BUILD.gn` 路径中的 BUILD.gn 文件，指定 `network_mqttclient_example` 参与编译。
|
||||
|
||||
```
|
||||
# "TW208_Module_ds1307:module_ds1307_example",
|
||||
# "TW209_Module_gps:module_gps_example",
|
||||
# "TW301_Network_wifista:network_wifista_example",
|
||||
# "TW302_Network_wifiap:network_wifiap_example",
|
||||
"TW303_Network_mqttclient:network_mqttclient_example",
|
||||
# "TW304_Network_httpclient:network_httpclient_example",
|
||||
# "TW305_Network_ntpclient:network_ntpclient_example",
|
||||
```
|
||||
|
||||
### 运行结果
|
||||
|
||||
示例代码编译烧录代码后，按下开发板的RESET按键，通过串口助手查看日志，会打印连接到的Wifi热点信息，以及订阅MQTT服务器主题，并接收发布后返回的结果。
|
||||
|
||||
```
