官网https://code.visualstudio.com/，直接下载安装即可。

参考
填入 http://arduino.esp8266.com/stable/package_esp8266com_index.json
打开开发板管理器找到ESP8266的包开始安装：
经常会出现下载失败的情况，换热点多试几次就好了，实在不行可以自行百度解决方法。
1.修改setting.json，加入两行代码，解决未定义标识符报错问题：
"C_Cpp.intelliSenseEngineFallback": "Disabled",
"C_Cpp.intelliSenseEngine": "Tag Parser",2.找到vscode的arduino拓展的安装目录，找到util.js这个文件并打开：
C:\Users\JustDooiT\.vscode\extensions\vsciot-vscode.vscode-arduino-0.4.2\out\src\common\util.js
将205 行处的如下代码注释掉，解决输出乱码问题：
3.到这里环境基本上已经配好了，可以开始写代码啦！在自己的工程目录下新建一个.ino文件，然后编写自己的代码。
4.代码写好之后，以ESP8266 NodeMCU 为例，我将开发板连接到电脑上后，首先要选择开发板型号和端口号，选完之后点击右上角按钮进行验证，验证无误后就可以进行烧录了。
一般来说，选择开发板型号并进行验证完之后会为我们自动生成一个.vscode文件夹：
里面有两个文件，arduino.json 和c_cpp_properties.json。其中arduino.json 包含一些关于开发板的配置信息，在验证完程序后会为我们自动修改；c_cpp_properties.json 用于配置编译器环境的，包括启动器代号、位数、编译选项、启动设置、编译模式、头文件路径等，这个文件比较重要，但一般不用我们管。如果没有自动生成该文件，可通过以下方法手动生成或者直接把别人的这个文件夹复制过来：
（1）创建c_cpp_properties.json 文件：
按Ctrl+Shift+P调出控制窗口，输入edit或者configuration，选择"C/Cpp:Edit Configurations"，然后就在.vscode文件夹下生成了c_cpp_properties.json文件。
（2）根据具体情况修改c_cpp_properties.json 文件：
查看ESP8266支持包的路径：
根据自己的头文件目录修改c_cpp_properties.json：
下面贴出我选择ESP8266 NodeMCU 后生成的c_cpp_properties.json 文件，大家可以参考格式自行修改。
