引子
众所周知，MDK的定义跳转和自动补全真的是一言难尽，没有编译的内容直接罢工跳转不了，自动补全也常年跳不出来，总想着要是能用VS Code看代码就好了。
如果直接用VS Code打开工程的话，又会报错满天飞，这个找不到路径，那个没有定义，为了解决这个问题，需要手动配置一下VS Code。
配置VS Code
VS Code打开文件夹后，会读取.vscode/c_cpp_properties.json的C/C++配置文件，在这个文件里可以指定包含路径、定义等，c_cpp_properties.json的基本结构如下，主要需要配置的内容是includePath（包含路径）和defines（宏定义）
{
"configurations": [
{
"name": "MDK Project",
"includePath": [],
"defines": [],
"intelliSenseMode": "${default}"
}
],
"version": 4
}包含路径
对于包含路径，可以使用相对路径和环境变量，对于手动添加的包含路径可以直接使用相对路径，例如需要包含工程下的/bsp文件夹：
"includePath": [
".\\bsp"
],对于RTE添加的文件，通常位于C:\Users\username\AppData\Local 路径下，其中 username 是当前用户的用户名，这个目录可以通过环境变量%LOCALAPPDATA%替代，例如需要包含CMSIS：
"includePath": [
"${env:LOCALAPPDATA}\\Arm\\Packs\\ARM\\CMSIS\\5.9.0\\CMSIS\\Core\\Include"
],除此之外，还需要包含编译器相关的文件，这里使用的是默认安装路径：
"includePath": [
"C:\\Keil_v5\\ARM\\ARMCLANG\\include",
"C:\\Keil_v5\\ARM\\ARMCLANG\\include\\arm_linux",
"C:\\Keil_v5\\ARM\\ARMCLANG\\include\\arm_linux_compat",
"C:\\Keil_v5\\ARM\\ARMCLANG\\include\\libcxx"
],宏定义
对于自定义的宏可以直接加入defines，例如定义STM32H750xx：
"defines": [
"STM32H750xx"
],除此之外，还需要包含一些特定的宏：
"defines": [
