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.

Chapter 6

  1. False. In this chapter, the ST-Link on the Nucleo development board was re-flashed to provide the same functionality as a J-Link.
  2. False. There are many ways to verify the timing requirements of a real-time system. Segger SystemView provides a means to measure response time, as does looking at system inputs and outputs via a traditional logic analyzer.
  3. False. An RTOS-aware debugger provides the ability to view all of the stacks in the system. This is also an option with any Open GDB-based debugging using Eclipse, as mentioned in the previous chapter.
  4. False. Each module that you write should be tested as thoroughly as possible to minimize any surprises and complex interactions when it is time to integrate the modules and perform a system-level test.
  5. Unit testing. In unit testing, each individual module is tested as it is developed. Integration testing is testing to ensure...
