Introduction to the mbed OS 5 Handbook
Welcome to the mbed OS 5 handbook.
If you’re new to all this, continue reading.
Developing applications on top of mbed OS
mbed OS lets you write applications that run on embedded devices, by providing the layer that interprets your application’s code in a way the hardware can understand.
Your application code is written in C++. It uses the application programming interfaces (APIs) that mbed OS provides. These APIs allow your code to work on different microcontrollers in a uniform way. This reduces a lot of the challenges in getting started with microcontrollers and integrating large amounts of software.
Where to start
If you’re working on Windows, you might need to install a serial driver.
The easiest way to work with mbed OS is using one of our development tools. We’ve set up an example, Blinky, that you can try on each of the tools. It will teach you to build and run an application on your board.
When you know how to build an existing application, it’s time to learn how to write your own applications.
- Our offline development tool is the mbed CLI, a command-line tool. This requires having a toolchain installed on your computer.
- The mbed Online Compiler lets you write and build applications using just a web browser and USB connection.
- If you’re working with third party tools, look at exporting instructions for the most popular ones.
Communicating with and monitoring your board
You can monitor and control an mbed board to help you debug and test your applications.
Tip: You can learn more about debugging here.
How to continue
When you’ve started writing applications using your selected development tool:
Learn about collaborative work and version control.
Try one of the advanced tutorials, which cover concepts such as debugging and memory trace.
We have a forum for questions and advice.

Porting to mbed OS
Our full porting guide is still being written. For now, we have:
