This repository contains a step-by-step guide that teaches you how to use Zephyr RTOS. It assumes:

• no previous experience with RTOS
• basic embedded electronics knowledge (GPIO, Timers, Interrupt,...)
• knowledge of C

Each lesson builds on the previous one. Most lessons end with exercises (with solutions!) that allow you to test your knowledge to make sure you understand everything that is covered.

This tutorial is under active development, if you want to participate - please read the Contribution guide.
