+# mqtt如何集成到系统Rom
+
+## 准备源码工程
+
+本库是基于OpenHarmony 3.2 beta4版本，在润和RK3568开发板上验证的。如果是从未使用过RK3568，可以先查看[润和RK3568开发板标准系统快速上手](https://gitee.com/openharmony-sig/knowledge_demo_temp/tree/master/docs/rk3568_helloworld)。
+
+### 准备系统Rom源码
+
+系统源码获取方法请参照：[OpenHarmony3.2beta4源码下载](https://gitee.com/openharmony/docs/blob/OpenHarmony-v3.2-Beta5/zh-cn/release-notes/OpenHarmony-v3.2-beta4.md#源码获取)
+
+### 增加构建脚本及配置文件
+
+- 下载本仓库代码
+
+  ```shell
+  cd ~/
+  git clone git@gitee.com:openharmony-sig/tpc_c_cplusplus.git --depth=1
+  ```
+
+- 仓库代码目录结构说明
+
+  ```shell
+  cd  ~/tpc_c_cplusplus/mqtt/  # 进入到仓库代码库目录
+  ```
+
+  ```shell
+  mqtt
+    |-- adapted           # 存放三方库适配需要的代码文件
+    |-- docs              # 存放 mqtt 相关文档的文件夹
+    |-- BUILD.gn          # 编译构建脚本
+    |-- bundle.json       # 三方库组件定义文件
+    |-- README_zh.md      # mqtt 主页说明文档
+    |-- README.OpenSource # mqtt 源码的下载地址，版本，license等信息
+  ```
+  
+- 将本仓库文件夹拷贝到OpenHarmony源码的third_party目录下
+
+  ```shell
+  cp -arf ~/tpc_c_cplusplus/mqtt ~/OpenHarmony/third_party
+  ```
+
+### 准备三方库源码
+
+- 三方库源码下载
+
+  将mqtt-1.3.12源码下载到mqtt目录并将代码拷贝出来。
+
+  ```shell
+  cd ~/OpenHarmony/third_party/mqtt
+  git clone https://github.com/eclipse/paho.mqtt.c.git -b v1.3.12
+  ```
+
+## 系统Rom中引入三方库
+
+准备完三方库代码后，我们需要将三方库加入到编译构建体系中。标准系统编译构建可以参考文档[编译构建指导](https://gitee.com/openharmony/docs/blob/OpenHarmony-3.2-Beta4/zh-cn/device-dev/subsystems/subsys-build-all.md)。  <br />
+我们默认三方库是属于OpenHarmony的thirdparty子系统，如果需要自己定义子系统参考文档[如何为三方库组件中添加一个三方库](https://gitee.com/openharmony-sig/knowledge/blob/master/docs/openharmony_getstarted/port_thirdparty/README.md)。<br />
+新增需要编译的组件,在OpenHarmony源码的vendor/hihope/rk3568/config.json文件中，新增需要编译的组件，如下代码段所示，在thirdparty子系统下面新增mqtt组件
+
+```json
+{
+  "subsystem": "thirdparty",
+  "components": [
+    {
+      "component": "musl",
+      "features": []
+    },
+    {
+      "component": "mqtt",
+      "features": []
+    }
+  ]
+}
+```
+
+## 系统Rom中引入三方库测试程序
+
+如果需要编译测试用例，在OpenHarmony源码的vendor/hihope/rk3568/config.json文件,在对应组件的features中打开编译选项，如下
+
+```json
+{
+  "subsystem": "thirdparty",
+  "components": [
+    {
+      "component": "musl",
+      "features": []
+    },
+    {
+      "component": "mqtt",
+      "features": []
+    }
+  ]
+}
+```
+
+## 编译工程
+
+- 进入源码根目录
+
+  ```shell
+  cd ~/openharmony
+  ```
+
+- 选择产品
+
+  ```shell
+  hb set    # 运行hb set后会出现产品列表，在此我们选择 rk3568
+  ```
+
+- 执行编译
+
+  ```shell
+  hb build --target-cpu arm      #编译32位系统
+  hb build --target-cpu arm64    #编译64位系统
+  ```
+
+- 生成的可执行文件和库文件都在out/rk3568/thirdparty/mqtt目录下，同时也打包到了镜像中
+
+## 运行效果
+
+将编译生成的库和测试文件放到板子上运行，为避免每次将文件推入设备都要烧录整个镜像，我们使用hdc_std工具将文件推到开发板上
+
+- 首先将hdc_std工具编译出来 </br>
+  执行以下命令进行编译hdc_std工具(工具编译出来所在路径out/sdk/ohos-sdk/windows/toolchains/hdc_std.exe):
+
+  ```shell
+  hb set     #源码根目录下使用hb set 选择产品ohos-sdk
+  hb build   #然后编译
+  ```
+
+- 将工具拷贝到Windows，可以为工具目录配置环境变量，也可以在工具所在目录打开windows命令行
+- 将原生库测试需要的所有文件打包成mqtt.tar,并拷贝到windows下
+- 将文件推送到开发板，在windows命令行进行如下操作
+  
+  ```shell
+  hdc_std shell mount -o remount,rw /    #修改系统权限为可读写
+  hdc_std file send mqtt.tar /           #将文件包推入开发板
+  hdc_std shell                          #进入开发板
+  tar xvf mqtt.tar                       #解压
+                                         #注意需要将库拷贝到/system/lib 或者/system/lib64目录下
+  ```
+  
+- 运行测试程序
+  在测试目录运行测试程序MQTTClient_subscribe，然后再另一个窗口运行测试程序MQTTClient_publish，则在订阅窗口会打印“Message arrived”，如下图所示：<br />
