Modern Embedded C with Zephyr RTOS: Develop Firmware Threads, Interrupts, Sensors, and Device Drivers

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 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. >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 More importantly, you will learn why these techniques matter. Rather than simply showing you which function to call, the book explains when to use a thread instead of a work queue, when a mutex is better than a semaphore, why some processing should never happen inside an interrupt handler, how Devicetree connects software to real hardware, and how to structure firmware so that adding the next feature does not break everything you already built. The examples are written in clear, modern C and developed around practical firmware situations. You will move from your first Zephyr application to concurrency, hardware control, sensor acquisition, communication, drivers, testing, reliability, and deployment. Whether you are an embedded developer moving beyond bare-metal C, a C programmer entering firmware development, an engineering student, or a maker ready to build more serious embedded systems, this book will help you develop the habits needed to create firmware that is responsive, organized, reliable, and easier to maintain. Stop treating growing firmware complexity as something you simply have to live with. Start building embedded systems with a structure designed to grow with your project.
