Zephyr RTOS is quickly becoming the operating system of choice for IoT, wearables, industrial systems, and safety-critical applications. Backed by the Linux Foundation and supported by major industry leaders, Zephyr combines the power of real-time scheduling with built-in connectivity, security, and scalability.

But while Zephyr is powerful, it can also feel complex and overwhelming for newcomers. That is where this book comes in.
