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.

Summary

In this chapter, we've covered three different APIs that can be used with FreeRTOS – the native FreeRTOS API, CMSIS-RTOS, and POSIX. You should now be familiar with all of the different APIs available for interacting with FreeRTOS and have an understanding of why they exist, as well as an understanding of when it is appropriate to use each one. Moving forward, you will be well positioned to make informed decisions about which API to use, depending on your particular project's requirements.

In the next chapter, we'll switch gears from discussing how to interact with FreeRTOS at a high level and discuss some of the low-level details of memory allocation.
