About Embedded Design With The PIC18F452
Product Description This book is developed around Microchip's latest family of parts, the PIC18FXXX family. It focuses on the PIC18F452, a new part brought to market in May 2002. It is intended that the reader will find a smooth path to the creative process of writing enhanced application code. This book attempts to organize and unify the development of these three capabilities: to understand and use components, to exploit powerful algorithmic processes, and to break down the complexity of an instrument or device so as to meet its specifications. The book is dedicated toward the development of creative design capability. Throughout this book, the approach taken is to introduce a template of assembly language code that encompasses a set of features of the PIC18F452 plus its interactions with some of the I/O devices resident on a small 4"x4" development board. For electrical engineers who work with the PIC18FXXX family. From the Back Cover John Peatman's latest microcontroller work focuses on Microchip Technology's PIC18FXXX family, and its newest member, the PIC18F452. The enhanced instruction set and addressing modes simplify program code development, and the on-chip resources make this the most powerful PIC microcontroller ever. Its flash program memory and built-in background debug mode provide internal programming/debugging support of program development. The presentation style throughout this book is to introduce the reader to simple programs that encompass features of the PIC18F452, plus interactions with I/0 devices, providing the reader with a smooth and quick learning process for creatively writing enhanced application code. Hundreds of figures give visual support to the text. Examples, end-of-chapter problems, suggested lab projects, complete designs, plus a QwikFlash development board support a "learning by doing" environment. About the Author John B. Peatman is a Professor of Electrical and Computer Engineering at the Georgia Institute of Technology. He is the author of five earlier digital design, microprocessor, and microcontroller textbooks. He is also a director with the Intelligent Systems Corporation. His current research interests include the design of low-cost development tools for microcontrollers. Professor Peatman is a Fellow of the IEEE. Excerpt. © Reprinted by permission. All rights reserved. The evolution of microcontrollers (i.e., single-chip microcomputers) has been driven by two strong trends. One trend is the demand for a low-cost means of putting intelligence into a product. When a product is produced in quantities of millions, a small savings in component cost will drive component selection decisions. Another trend is the demand for a programmable solution when an application has severe timing constraints, such as those in automobile engine control. This demand has led to ever faster, more sophisticated microcontroller architectures. Microchip Technology has evolved its product line of PIC microcontrollers from simple, low-cost devices. Subsequent generations of PIC microcontrollers have included enhancements to meet the needs of an increasing circle of applications. At the same time, Microchip has never lost sight of the value of introducing new technology at the lowest possible cost and thereby "buying" market share. As pointed out in Chapter 1 of this text, Microchip has followed this strategy to the point where it is now the number two producer of eight-bit microcontrollers in the world, with a market share that continues to rise each year. Because eight-bit microcontrollers span the needs of most applications, "eight-bitters" dominate the world of microcontrollers. This book is developed around Microchip's latest family of parts, the PIC I8FXXX family. It focuses on the PIC 18F452, a new part brought to market in May 2002. It is a 40-pin microcontroller upgrade of their earlier PIC 16C74 and PIC 16F877 microcontrollers. This upgrade will be familiar to users
