Book Description
This updated edition of Hands-On RTOS with Microcontrollers is packed with cutting-edge content to help you expand your skills and stay ahead of the curve with embedded systems development. Written by senior engineers with decades of experience in embedded systems and related technologies, it covers the role of real-time OSs in today’s time-critical applications, and it covers FreeRTOS, including its key capabilities and APIs. You’ll find detailed descriptions of system design, hands-on system use, the hardware platform (dev-board, MCU, and debug-probe), and the development tools (IDE, build system, and debugging tools).
This second edition teaches you how to implement over 20 real-world embedded applications, using FreeRTOS's primary features. The chapters include example programs on GitHub, with detailed instructions. You’ll create and install your own FreeRTOS system on the dev-board (purchased separately), and set up an IDE project with debugging tools.
An ST dev-board is used with the book, and it is purchased separately (STM32 Nucleo-F767ZI - the dev-board is not required to read and understand the book).
By the end of this book, you’ll have the hands-on skills to start designing, building, and optimizing embedded applications, using FreeRTOS, development boards, and debugging tools.
What you will learn
- Understand RTOS use cases, and decide when (and when not) to use real-time OS
- Use the FreeRTOS scheduler to create, start, and monitor task states
- Improve task signaling and communication using queues, semaphores, and mutexes
- Streamline task data transfer with queues and notifications
- Upgrade peripheral communication via UART, USB, and DMA by using drivers and ISRs
- Enhance interface architecture with a command queue for optimized system control
- Maximize FreeRTOS memory management with trade-off insights
Who this book is for
This book is for systems programmers, embedded systems engineers, and software developers who want to learn about real-time operating systems (RTOS) and how to use FreeRTOS in their embedded system design. A basic understanding of the C programming language, embedded systems, and microcontrollers is assumed. The book also includes hardware tutorials for systems programmers.

Jim Yuill is a senior computer-systems engineer, with 30 years of experience. He has worked in operating-systems development, cyber-security R&D, network systems-programming, and university teaching. He has a PhD in computer science, with a thesis in cyber security, which is highly cited.
Penn Linder is a Senior Electrical Engineer at IVEK Corporation, a manufacturer of industrial pumps and controllers. He has had a passion for embedded systems since taking his first embedded controllers' class at Penn State University in 1995. He followed his passion by working for various companies that allowed him to design both hardware and software for products using embedded systems. Some of the products he has worked on include lighting controls, medical devices, and industrial automation equipment. His early years were spent cranking out bare-metal assembly code for 8-bit MCUs. In his later years, he wrote software using C and FreeRTOS for 32-bit ARM Cortex-M processors.
