By Tim Wilmshurst, University of Derby, UK
Description This book is a hands-on introduction to the principles and practice of embedded system design using the PIC microcontroller. Packed with
helpful examples and illustrations, it gives an in-depth treatment of microcontroller design, programming in both assembly language and
C, and features advanced topics such as networking and real-time operating systems. It is accompanied by a CD-ROM containing copies of
all programs and software tools used in the text and a ?student? version of the C complier.
Designing Embedded Systems with
PIC Microcontrollers: Principles and Applications is ideal for students of electronics, mechatronics and computer engineering.
Engineers in industry and informed hobbyists will also find this book a valuable resource when designing and implementing both simple
and sophisticated embedded systems using the PIC Microcontroller.
Support material, including new and supporting information, links
to useful sites, and errata, is available from the book's companion site .
Audience
Professional engineers developing embedded systems, informed hobbyists and engineering students.
