前言：本文主要介紹如何在機智云平臺創(chuàng)建一個智能產品、定義功能數(shù)據(jù)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；

什么是Product Key、Product Secret

Product Key又稱產品標識碼，開發(fā)者通過機智云后臺創(chuàng)建新產品后，自動生成的一個32位字符串。在機智云的數(shù)據(jù)庫中是一個唯一的號碼，開發(fā)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(shù)，該參數(shù)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(shù)。在開發(fā)MCU過程中，需要使用到該參數(shù)。

根據(jù)系統(tǒng)的需求添加數(shù)據(jù)點，可參考本系統(tǒng)數(shù)據(jù)點

什么是數(shù)據(jù)點？

數(shù)據(jù)點即設備產品的功能的抽象，用于描述產品功能及其參數(shù)。創(chuàng)建數(shù)據(jù)點后，設備與云端通訊的數(shù)據(jù)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(lián)互通的數(shù)據(jù)。

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

3.1 創(chuàng)建好數(shù)據(jù)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(fā)或正在開發(fā)的智能硬件，來進行云端設備控制、手機APP控制、上報數(shù)據(jù)等需求。

開發(fā)者或企業(yè)研發(fā)人員在機智云平臺開發(fā)時，如果正式的智能硬件產品產品還未完全開發(fā)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(fā)周期，降低研發(fā)成本。

3.2 在機智云APP能夠觀察機智云平臺模擬的數(shù)據(jù)

根據(jù)系統(tǒng)的需要添加或修改數(shù)據(jù)點信息

4.1 在確定數(shù)據(jù)點無誤后，點擊MCU開發(fā)

4.2 生成代碼包后，把代碼包導入Arduino IDE開發(fā)環(huán)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

5.1 在應用開發(fā)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'  implementation files('libs/BLEasyConfig.jar')  implementation files('libs/easylink2.0.jar')  implementation files('libs/GizWifiSDK.jar')  implementation files('libs/jpush-android-2.1.5.jar')  implementation files('libs/Lark7618SDK_noudp1606031910_0101.jar')  implementation files('libs/libammsdk.jar')  implementation files('libs/libForEElink.jar')  implementation files('libs/LSFSK_1.0.jar')  implementation files('libs/ltlink2.jar')  implementation files('libs/mta-sdk-1.6.2.jar')  implementation files('libs/OneShotConfig.jar')  implementation files('libs/open_sdk_r5756.jar')  implementation files('libs/pushservice-5.6.0.30.jar')  implementation files('libs/simpleconfigwizardlib.jar')  implementation files('libs/xUtils-2.6.14.jar')  implementation files('libs/zxing.jar')  implementation 'com.android.support25.3.0'  implementation 'com.yanzhenjie1.0.5'}
