VSCODE（Visual Studio Code）编写C51代码，环境配置，实现自动补全，C51关键字处理方法_vscode写c51

vscode: ctrl + shift + p,输入>edit configurations 选择后面是JSON的项运行，生成c_cpp_properties.json配置文件
defines：字段定义C51特有关键字，数据类型转为C数据类型，其他关键字加“=”号即可。这样配置之后C51特有关键字定义的数据类型就不会报错，并且可以自动补全。

includePath:字段添加工程代码路径，因使用到了Keil相关文件所有也要添加"C:\Keil\C51\INC"。
