VS Code c_cpp_properties.json example for arm-none-eabi toochain

If you installed C/C++ extension for Visual Studio Code but using GNU Arm Embedded Toolchain for ARM Cortex M series MCU target, VS Code will keep prompt "Configuring includePath for better IntelliSense results". You wil need a special c_cpp_properties.json for the ARM toolchain.

This works on both Linux and Windows.

1. For arm-none-eabi-gcc users, its compiler include path should be included first. It differes in each system. Use the verbose arm-none-eabi-gcc -v flag to see include list. change "includePath" and "browse"."path" for your sys
