Modern Embedded C with Zephyr RTOS

Your embedded project works-until interrupts, multiple sensors, timing requirements, and shared hardware turn a simple C program into firmware that is difficult to control.
Modern embedded development demands more than writing a while loop and manipulating registers. As devices become more capable, your firmware needs to handle several tasks reliably, respond to hardware events quickly, communicate with peripherals, manage shared resources safely, and remain maintainable as the project grows.

Modern Embedded C with Zephyr RTOS gives you a practical path from basic embedded C to structured, production-style firmware using one of today's most capable real-time operating systems.
Instead of teaching Zephyr as a collection of disconnected commands and APIs, this book shows you how the pieces fit together-and, more importantly, how to use them to solve real embedded problems.

You will learn how to:

• • Build, configure, flash, and debug Zephyr applications with confidence
• • Understand Kconfig, Devicetree, boards, devices, and the Zephyr build process
• Write safer embedded C using fixed-width types, pointers, structures, memory rules, and clean module design
• Divide firmware into responsive threads without creating scheduling problems
• Use semaphores, mutexes, queues, events, and other synchronization tools to move data safely
• Handle interrupts correctly while keeping time-critical code fast
• Use timers, work queues, and deferred processing for responsive event-driven firmware
• Control real hardware with GPIO, PWM, and ADC
• Communicate with sensors and peripherals using UART, I2C, and SPI
• Build sensor-based applications that collect, validate, filter, and process real measurements
• Understand Zephyr's driver model and create your own custom device driver
• Diagnose crashes, stack problems, timing bugs, communication failures, and unexpected resets
• Organize multiple components into a complete production-style Zephyr application
