前言：本文主要介紹如何在機智云平臺創建一個智能產品、定義功能數據點、生成MCU代碼包并附上修改好的代碼、生成APP代碼編譯附上參考代碼。

需準備的硬件主要有Arduino uno R3、ESP8266

連線方式：A0讀取模擬電壓輸入；Key1接到D6；Key2接到D7；LED接到D4；

一、創建項目

1.1 創建新產品

登陸機智云AIoT開發平臺 dev.gizwits.com 創建智能產品

1.2 進入項目可查看信息

什么是Product Key、Product Secret

Product Key又稱產品標識碼，開發者通過機智云后臺創建新產品后，自動生成的一個32位字符串。在機智云的數據庫中是一個唯一的號碼，開發者將ProductKey寫入設備主控MCU后，機智云通過此標識碼對設備進行識別并自動完成注冊。

設備接入機智云的前提是，需要機智云認同這個設備。Productkey是設備接入機智云的一個重要參數，該參數的基本含義是：一款設備識別碼。例如某公司生產空調、熱水器，空調和熱水器是不同款設備，該公司設備接入機智云，至少需要兩個Productkey參數。在開發MCU過程中，需要使用到該參數。

二、添加數據點

根據系統的需求添加數據點，可參考本系統數據點

什么是數據點？

數據點即設備產品的功能的抽象，用于描述產品功能及其參數。創建數據點后，設備與云端通訊的數據格式即可確定，設備、機智云可以相互識別設備與機智云互聯互通的數據。

參考：http://docs.gizwits.com/zh-cn/quickstart/UseMCU.html

三、進行虛擬設備調試

3.1 創建好數據點后，進行虛擬設備調試

什么是虛擬設備？類似一款仿真器，能夠模擬硬件設備。

虛擬設備是機智云云端可自動生成的一個仿真智能硬件，可模擬要開發或正在開發的智能硬件，來進行云端設備控制、手機APP控制、上報數據等需求。

開發者或企業研發人員在機智云平臺開發時，如果正式的智能硬件產品產品還未完全開發完成，就可以很方便地使用該“虛擬設備”與正式產品的控制APP進行調試和驗證，加快研發周期，降低研發成本。

3.2 在機智云APP能夠觀察機智云平臺模擬的數據

根據系統的需要添加或修改數據點信息

四、下載MCU代碼包

4.1 在確定數據點無誤后，點擊MCU開發

4.2 生成代碼包后，把代碼包導入Arduino IDE開發環境的libraries文件中，libraries是Arduino的庫文件，包含自帶的庫文件和用戶添加的外部庫文件

把networkConfig.ino的配網代碼移植到simpleTry.ino,把串口打印的代碼注釋起來，可參考資料分享：史上最詳細的Arduino uno R3接入機智云教程

五、下載Android開發代碼包

5.1 在應用開發生成APP代碼包

通過Android Studio軟件導入項目進行編譯，因版本問題需要修改關鍵詞，compile 均替換為implementation，testcompile均替換為testimplementation，可參考以下代碼：

apply plugin: 'com.android.application'

android {

  compileSdkVersion 25

  buildToolsVersion '28.0.2'

  useLibrary 'org.apache.http.legacy'

  defaultConfig {

    applicationId "com.gizwits.opensource.appkit"

    minSdkVersion 16

    targetSdkVersion 25

    versionCode 1

    versionName "2.5.1.072715"

    multiDexEnabled true

  }

  buildTypes {

    release {

      minifyEnabled false

      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

    }

  }

}

dependencies {

  implementation fileTree(dir: 'libs', include: ['*.jar'])

  implementation 'com.android.support.constraint1.1.0'

  testImplementation 'junit4.12'

  implementation 'com.android.support24.2.1'
