Arm Mbed OS is an open source embedded operating system designed specifically for the "things" in the Internet of Things. It includes all the features you need to develop a connected product based on an Arm Cortex-M microcontroller, including security, connectivity, an RTOS and drivers for sensors and I/O devices.

Mbed OS provides a platform that includes:

• Security foundations.
• Cloud management services.
• Drivers for sensors, I/O devices and connectivity.

This is Mbed OS Community Edition (CE), a fork focused on improving the build system and tooling, fixing bugs, and keeping maintenance going after ARM's step back from the Mbed project.

The software is provided under the Apache-2.0 license. Contributions to this project are accepted under the same license. Please see contributing.md for more information.

This project contains code from other projects. The original license text is included in those source files. They must comply with our license guide.

Folders containing files under different permissive license than Apache 2.0 are listed in the LICENSE file.

To start a new project that uses Mbed CE, see the setup guide here.

We have a developer website for asking questions, engaging with others, finding information on boards and components, using an online IDE and compiler, reading the documentation and learning about what's new and what's coming next in Mbed OS.

Additionally, the discussions page on this repo can be used for proposing and discussing specific code changes.

For more information about Mbed OS, please see the published Mbed OS documentation. It includes general overview information, step-by-step tutorials, porting information and background reference materials about our architecture and tools.
