    During the development of an engineered product, developers often need to create an embedded system—a prototype—that demonstrates the operation/function of the device and proves its viability. Offering practical tools for the development and prototyping phases, Embedded Systems Circuits and Programming provides a tutorial on microcontroller programming and the basics of embedded design.

    The book focuses on several development tools and resources:

    • Standard and off-the-shelf components, such as input/output devices, integrated circuits, motors, and programmable microcontrollers
    • The implementation of circuit prototypes via breadboards, the in-house fabrication of test-time printed circuit boards (PCBs), and the finalization by the manufactured board
    • Electronic design programs and software utilities for creating PCBs
    • Sample circuits that can be used as part of the targeted embedded system
    • The selection and programming of microcontrollers in the circuit

    For those working in electrical, electronic, computer, and software engineering, this hands-on guide helps you successfully develop systems and boards that contain digital and analog components and controls. The text includes easy-to-follow sample circuits and their corresponding programs, enabling you to use them in your own work. For critical circuits, the authors provide tested PCB files.

    Biography

    Julio Sanchez is a professor emeritus of computer science at Minnesota State University. He is the author of over twenty-five books, with many translated into Chinese, Indonesian, Japanese, Korean, and Polish.

    Maria P. Canton is the co-author of over twenty books, with many translated into Chinese, Indonesian, Japanese, Korean, and Polish. She earned a Ph.D. in computer science from North Dakota State University.

    "I was very positively impressed by this book. It may serve as self-contained design compendium giving suitable technical background, technical documentation of Microchip 16-bit microcontrollers and plenty of design examples. The book may be strongly recommended for academic courses in digital design. It may also be helpful for designers in industry."
