This slightly revised 4th edition includes two example projects from the earlier editions not found in the third edition but is otherwise unchanged. As before it includes a massive amount of information about the 8051-family of microcontrollers and techniques for programming them in the C language. There is a strong emphasis on interrupt-driven programming and operating systems as well as many algorithms related to typical microcontroller interfacing. There is extensive ground-up coverage of serial interfacing and small-area networks.

This book describes the people, places, and practices of Prince Edward Island, Canada (the smallest province, located just north of Nova Scotia in Atlantic Canada) as seen by a recent newcomer. From away is the local term for anyone not born on the island, no matter how long they have lived there. This book can be a useful visitor's guide or a tool to help long-time Islanders recover an appreciation for the things they have stopped noticing because of long familiarity.
