Hands-On RTOS with Microcontrollers

By: Brian Amos

Overview of this book

A real-time operating system (RTOS) is used to develop systems that respond to events within strict timelines. Real-time embedded systems have applications in various industries, from automotive and aerospace through to laboratory test equipment and consumer electronics. These systems provide consistent and reliable timing and are designed to run without intervention for years. This microcontrollers book starts by introducing you to the concept of RTOS and compares some other alternative methods for achieving real-time performance. Once you've understood the fundamentals, such as tasks, queues, mutexes, and semaphores, you'll learn what to look for when selecting a microcontroller and development environment. By working through examples that use an STM32F7 Nucleo board, the STM32CubeIDE, and SEGGER debug tools, including SEGGER J-Link, Ozone, and SystemView, you'll gain an understanding of preemptive scheduling policies and task communication. The book will then help you develop highly efficient low-level drivers and analyze their real-time performance and CPU utilization. Finally, you'll cover tips for troubleshooting and be able to take your new-found skills to the next level. By the end of this book, you'll have built on your embedded system skills and will be able to create real-time systems using microcontrollers and FreeRTOS.

This hands-on guide will provide you with the most important functional knowledge for getting a Real-Time Operating System (RTOS) up and running on a microcontroller unit (MCU). If you're interested in learning how to implement applications using an RTOS with hands-on examples using actual hardware and discussing common performance versus development-time trade-offs, you're in the right place!

We'll be implementing code using the FreeRTOS kernel, working with the popular STM32 ARM MCUs using a low-cost STM Nucleo development board, and debugging/analyzing code with SEGGER debug tools. All of the tools used in this book have been selected because they are easily accessible for the hobbyist or professional just getting started, and also because of their popularity in real-world professional teams. The knowledge and experience you gain through reading this book and working through the examples will be directly applicable to actual development in a professional environment.
