Introduction to the mbed OS 5 Handbook

Welcome to the mbed OS 5 handbook.

If you’re an experienced mbed applications developer, you might want to dive straight into the API References, or take a look at our development tools documentation.

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 - written in C++ - uses the application programing interfaces (APIs) presented by mbed OS to receive information from the hardware and send instructions to it. This means that a lot of the challenges in getting started with microcontrollers or integrating large amounts of software is already taken care of.

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.

Development tools

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
