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.

How our development board was selected

Now that we've covered the important considerations for MCU selection and the general types of development hardware, let's see how the development board that will be used in this book was selected. STM is the only manufacturer that we are evaluating in order to limit the examples to something easily digestible. In an actual product engineering effort, it behooves the designer to take a fresh look at all possible vendors. While everybody has their own preferred way of accomplishing cross-vendor searches, an easy way is to use distributor websites.

Thanks to well-curated prototyping-oriented distributor websites (such as Digikey and Mouser), an engineer is able to perform parametric searches and comparisons across many different vendors. One downside to this approach is the searches are limited to whatever product lines that specific...
