mponent of our everyday lives. We interact with hundreds of tiny computers every day that are embedded into our houses, our cars, our toys, and our work. As our world has become more complex, so have the capabilities of the microcontrollers embedded into our devices. The ARM(R) CortexTM-M family, first introduced in 2003, is much more powerful than the devices available previously. The purpose of this book is to present the design methodology to train young engineers to understand the basic building blocks that comprise devices like a cell phone, an MP3 player, a pacemaker, antilock brakes, and an engine controller.

This book, now in its 9th printing, is the second in a series of three books that teach the fundamentals of embedded systems as applied to the TM4C123/MSP432E family of microcontrollers. The three books are primarily written for undergraduate electrical and computer engineering students. They could also be used for professionals learning the ARM platform. The first book Embedded Systems: Introduction to ARM Cortex-M Microcontrollers is an introduction to computers and interfacing focusing on assembly language and C programming. This second book focuses on interfacing and the design of embedded systems. The third book Embedded Systems: Real-Time Operating Systems for ARM Cortex-M Microcontrollers is an advanced book focusing on operating systems, high-speed interfacing, control systems, and robotics.
An embedded system is a system that performs a specific task and has a computer embedded inside. A system is comprised of components and interfaces connected together for a common purpose. This book presents components, interfaces and methodologies for building systems. Specific topics include the architecture of microcontrollers, design methodology, verification, hardware/software synchronization, interfacing devices to the computer, timing diagrams, real-time operating systems, data collection and processing, motor control, analog filters, digital filters, real-time signal processing, wireless communication, and the internet of things.

This book employs many approaches to learning. It will not include an exhaustive recapitulation of the information in data sheets. First, it begins with basic fundamentals, which allows the reader to solve new problems with new technology. Second, the book presents many detailed design examples. These examples illustrate the process of design. There are multiple structural components that assist learning. Checkpoints, with answers in the back, are short easy to answer questions providing immediate feedback while reading. Simple homework, with answers to the odd questions on the web, provides more detailed learning opportunities. The book includes an index and a glossary so that information can be searched. The most important learning experiences in a class like this are of course the laboratories. Each chapter has suggested lab assignments. More detailed lab descriptions are available on the web. Specifically, look at the lab assignments for ECE445L and ECE445M.
There is a web site accompanying this book https: //users.ece.utexas.edu/ valvano/EE445L/. Posted here are ARM Keil uVision projects for each the example programs in the book. Code Composer StudioTM versions are also available for most examples. You will also find data sheets and Excel spreadsheets relevant to the material in this book.
These three books will cover embedded systems for ARM(R) CortexTM-M microcontrollers with specific details on the TM4C123 and TM4C1294/MSP432E401Y. Most of the topics can be run on the low-cost TM4C123. Ethernet examples can be run on the MSP432E401Y. In these books the term TM4C will refer to any of the Tiva line of TI ARM(R) CortexTM-M based microcontrollers. Although the solutions are specific for the TM4C family, it will be possible to use these books for other ARM derivatives.
