VS Code Mbed

VS Code Extension for Mbed OS Projects.

Overview

Mbed for VS Code enables you to work with Mbed OS projects, handling library dependencies, target connection, build, debug and serial output.

Usage

• Install the extension from within your IDE (search for 'mbed') or from an extension marketplace:

  • VS Code: https://marketplace.visualstudio.com/items?itemName=mbed.mbed
  • Open VSX: https://open-vsx.org/extension/mbed/mbed

• This will also install the following extensions:

  • arm.armls - For working with assembly code.
  • arm.device-manager - For detecting and managing connected devices.
  • arm.embedded-debug - For deploying to your device and debugging programs.
  • arm.environment-manager - For setting up a compiler.

• Open an existing Mbed OS project or use the user interface to clone an existing example using git.

• The user interface will help you recursively clone any dependant libraries (hydration) and install the Arm GNU toolchain (GCC) or Arm Compiler for Embedded toolchains.

• You can then select your target and profile, build, deploy and debug your application.

Contribution

This extension is intended to serve as a permissive, open-source reference for working with Mbed after the July 2026 end-of-life, offering an alternative to the standalone Mbed Studio application.

Pull requests may be accepted, but this primarily serves as a reference application for developing your own tools.
