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.What you will learn Understand when to use an RTOS for a project Explore RTOS concepts such as tasks, mutexes, semaphores, and queues Discover different microcontroller units (MCUs) and choose the best one for your project Evaluate and select the best IDE and middleware stack for your project Use professional-grade tools for analyzing and debugging your application Get FreeRTOS-based applications up and running on an STM32 board Who this book is for This book is for embedded engineers, students, or anyone interested in learning the complete RTOS feature set with embedded devices. A basic understanding of the C programming language and embedded systems or microcontrollers will be helpful.

Embedded software has traditionally been developed as a one-off software development effort designed for an individual product. In recent years, embedded system complexity has dramatically increased and the microcontrollers capabilities have followed. What were once simple 8-bit computing machines running at a few dozen megahertz have now become full-fledged 32-bit processors executing at hundreds of megahertz's. Developing software from scratch or for use in a single application or processor has become extremely costly and problematic for design teams. This API standard for microcontrollers is an example hardware abstraction layer designed to help embedded software developers designing products with microcontrollers create reusable software that abstracts out the hardware. This API standard has been developed and used in production systems for more than half a decade in devices ranging from automotive and medical devices to space systems. Each iteration that it has gone through has helped create a standard that flexible for developers and meets many general real-time design needs. Using an API to abstract out the microcontroller has several major benefits to development teams such as: Removing the specialized need to master the microcontroller hardware Decreasing costs through reusable firmware Faster times to market Better planning and accuracy in the development cycle Portability and flexibility to handle numerous applications Undoubtedly there are many more benefits but in this book the goal is to provide the reader with the standard. If you are interested in understanding how to develop reusable software and the processes that a developer would go through to create their own API's and HAL's, the companion book "Developing Reusable Firmware : A Practical Approach", can be found at www.beningo.com. Developing Reusable Firmware discusses the key ideas behind creating API's and HAL's along with the processes and design considerations that developers need to consider when creating their own. This standard example has gone through many iterations and has become very stable but there is always an opportunity that changes will be made in the future. In order to stay up to date and receive the latest information and also receive the associated API template files, please visit the associated webpage at https://www.beningo.com/api/index.php to sign-up. When you sign-up you will receive Doxygen template source files that layout the entire standard in way that can be easily modified to implement in your own development cycle. I wish you the best of luck in using this standard and dramatically transforming the way in which you develop and reuse your embedded software.

Embedded core processors are becoming a vital part of today's system-on-a-chip in the growing areas of telecommunications, multimedia and consumer electronics. This is mainly in response to a need to track evolving standards with the flexibility of embedded software. Consequently, maintaining the high product performance and low product cost requires a careful design of the processor tuned to the application domain. With the increased presence of instruction-set processors, retargetable software compilation techniques are critical, not only for improving engineering productivity, but to allow designers to explore the architectural possibilities for the application domain. Retargetable Compilers for Embedded Core Processors, with a Foreword written by Ahmed Jerraya and Pierre Paulin, overviews the techniques of modern retargetable compilers and shows the application of practical techniques to embedded instruction-set processors. The methods are highlighted with examples from industry processors used in products for multimedia, telecommunications, and consumer electronics. An emphasis is given to the methodology and experience gained in applying two different retargetable compiler approaches in industrial settings. The book also discusses many pragmatic areas such as language support, source code abstraction levels, validation strategies, and source-level debugging. In addition, new compiler techniques are described which support address generation for DSP architecture trends. The contribution is an address calculation transformation based on an architectural model. Retargetable Compilers for Embedded Core Processors will be of interest to embedded system designers and programmers, the developers of electronic design automation (EDA) tools for embedded systems, and researchers in hardware/software co-design.

Barr Group's Embedded C Coding Standard was developed to help firmware engineers minimize defects in embedded systems. Unlike the majority of coding standards, this standard focuses on practical rules that keep bugs out - including techniques designed to improve the maintainability and portability of embedded software. The rules in this coding standard include a set of guiding principles, as well as specific naming conventions and other rules for the use of data types, functions, preprocessor macros, variables, and other C language constructs. Individual rules that have been demonstrated to reduce or eliminate certain types of defects are highlighted. The BARR-C standard is distinct from, yet compatible with, the MISRA C Guidelines for Use of the C Language in Critical Systems. Programmers can easily combine rules from the two standards as needed.
