How to Develop Embedded Software Using the QEMU Machine Emulator
This e-book has been written for embedded software developers by Apriorit experts. It goes in-depth on how to save time when developing a Windows device driver by emulating a physical device with QEMU and explores the details of device driver emulation based on QEMU virtual devices. Key Highlights ⦁ Develop a Windows device driver without a physical device ⦁ Learn to securely test device drivers, find and fix defects ⦁ Leverage the QEMU machine emulator for your needs Book Description Developing a Windows driver for an embedded device is a very specific task, as this software should ensure stable and secure communication between operating system and a highly specialized device. Besides, in the world of ever increasing competitiveness, manufacturers tend to force developers to start working on embedded software before hardware is manufactured. Fortunately, developers can emulate a physical device using virtualization technologies like QEMU. After creating a virtual device in QEMU, developers can use it not only for a device driver development but also for its testing and fixing defects. In this e-book, the author shares his practical experience on developing Windows drivers using a QEMU virtual device. You’ll dive deep into driver implementation process and learn about all the benefits and limitations of device emulation in QEMU. The e-book includes detailed steps to establish communication between a device and its driver. It also shows how to use QEMU for building running, testing, and debugging the whole environment. This approach was tested by Apriorit team for quite a long time, so it has already confirmed its value and effectiveness. What you will learn ⦁ Dive into driver implementation stages ⦁ Weigh up the pros and cons of using a QEMU virtual device ⦁ Initialize the device in QEMU ⦁ Develop your own Windows driver for a QEMU virtual hardware ⦁ Establish communication between a device and its driver ⦁ Process requests from a user mode application ⦁ Use QEMU for building running, testing, and debugging embedded software About the Author Artem Kotovsky is a Software Analyst at Apriorit Inc.

Developing Embedded Systems with Zephyr OS
"Developing Embedded Systems with Zephyr OS" "Developing Embedded Systems with Zephyr OS" is a comprehensive guide crafted for engineers, developers, and technical architects aiming to harness the power of the Zephyr real-time operating system in modern embedded applications. This book meticulously explores Zephyr’s modular architecture, detailing its microkernel design, kernel scheduler, and the powerful hardware abstraction enabled by Kconfig and Devicetree. Starting from a solid grounding in system design, memory management, and architectural portability, readers gain a deep understanding of the foundational elements needed to construct robust, portable, and scalable IoT solutions across diverse MCU platforms. A hands-on approach takes readers through the set-up and optimization of the Zephyr development environment, including toolchain integration, board porting, and build automation using CMake and west. Special attention is devoted to critical RTOS concepts such as threading, synchronization, and inter-process communication, as well as best practices for developing reliable device drivers and leveraging Zephyr’s advanced networking stack for wireless and wired connectivity. In-depth coverage of filesystems, storage management, and secure over-the-air firmware updates ensures your embedded devices remain resilient, maintainable, and future-proof in demanding deployments. Security, power optimization, and advanced development workflows form the cornerstone of the book’s later chapters, with practical guidance on secure coding, cryptographic integration, and leveraging hardware isolation features such as TrustZone. Detailed discussions on energy profiling, low-power patterns, and energy harvesting techniques empower developers to create devices that balance rich functionality with extended battery life. The final chapters encapsulate best practices, diagnostic tools, open-source collaboration, and a forward-looking perspective on evolving trends within the Zephyr ecosystem, making this book an essential companion for professionals building the next generation of connected embedded systems.
