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.

In this chapter, we introduced the concept of an IDE and why you might choose to use one. A list of considerations was presented, along with categories of IDEs and suggestions for when it is best to use them. All of this material was put to use as we selected the IDE used in this book. Finally, we took a look at STMCubeMX and discussed how it can be used in different stages of a project.

Having a good understanding of the trade-offs to be made when designing a workflow (which includes choosing software tools) for your embedded system's code development will help you to make informed decisions, which can make a huge impact on productivity.

In the next chapter, we'll continue looking at tools for increasing productivity on FreeRTOS-based embedded firmware projects. The next set of tools allows you to actually see how your code is behaving in an extremely convenient...
