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.

Selecting the IDE used in this book

Now that we've categorized several different IDEs, it's time to consider which one will be used for the example code covered in the remainder of this book. In keeping with the low-cost theme in order to reduce the barriers to entry, we're going to focus on the IDEs that don't require any monetary investment—anything that is freely available for non-professional use (without time or code limits) can be considered. This immediately eliminates Keil uVision, IAR Embedded Workbench, and SysProgs Visual GDB. Keil has a free version that is code-limited to 32 KB, but we might use that up quickly, depending on how much middleware we elect to include in the examples.

Since a large part of this book also covers debugging with a J-Link probe, we'd like to have an IDE that supports either J-Link or GDB, as well. In a perfect...
