Zephyr RTOS Cookbook. Build portable and scalable embedded systems through hands-on recipes

Adopting Zephyr RTOS can feel very different from working with bare-metal systems, traditional RTOSes, or embedded Linux. Instead of tightly coupled board-specific code, Zephyr follows a platform-oriented approach built around reusable components, standardized subsystems, and configuration-driven behavior. This shift can be unfamiliar at first, especially for developers moving to Zephyr for real-world products. Zephyr RTOS Cookbook is a recipe-led guide designed to help you make that transition with confidence. Rather than treating Zephyr as just a kernel, the book shows how to work with it as a complete platform. You’ll learn how to structure projects using West-managed, multi-repo workspaces, enable and customize system features with Kconfig, and describe hardware cleanly using DeviceTree to keep applications portable across boards. Each recipe focuses on a practical task you’ll encounter when building Zephyr-based systems, from integrating drivers and subsystems to reasoning about initialization order, device availability, and permissions at runtime. By the end of the book, you’ll be able to develop maintainable Zephyr applications, adapt them to different hardware configurations, and confidently scale your codebase across projects and teams. *Email sign-up and proof of purchase required
