This textbook serves as an introduction to the subject of embedded systems design, using microcontrollers as core components. It develops concepts from the ground up, covering the development of embedded systems technology, architectural and organizational aspects of controllers and systems, processor models, and peripheral devices. Since microprocessor-based embedded systems tightly blend hardware and software components in a single application, the book also introduces the subjects of data representations formats, data operations, and programming styles. The practical component of the book is tailored around the architecture of a widely used Texas Instruments microcontroller, the MSP430. Instructors supplemental materials available through the book web site include solutions to selected problems and exercises and power point slides for lectures. The site also includes materials for students that include links to application examples and to sites elsewhere in the web with application notes, downloadable tools, and part suppliers. Provides textbook coverage of embedded systems, with an emphasis on the practical use of microcontrollers; Covers embedded software fundamentals, including software planning, assembly language, and C-language program development; Includes detailed treatment of embedded hardware fundamentals, discussing structure, interfacing and configuration of hardware building blocks; Emphasizes examples and exercises that reflect real applications for embedded systems design; Covers all MSP430 generations up to series x6xx.
