What you need to know before reading the guide

This guide assumes that you are familiar with C++. While we do discuss how we applied some concepts in mbed OS, we don’t explain the background to these concepts in any great detail. If you know C but not C++, you might find this Coursera module helpful.

The examples in this guide focus on the FRDM-K64F board. If you have another board, you’ll have to check if it’s already supported on mbed OS before you run the sample code. You should be able to follow the code and explanations even if you don’t have compatible hardware.
