The vast majority of computers in use today are encapsulated within other systems. In contrast
to general-purpose computers that run an endless selection of software these embedded
computers are often programmed for a very specific low-level and often mundane purpose.
Low-end microcontrollers costing as little as one dollar are often employed by engineers in
designs that utilize only a small fraction of the processing capability of the device because
it is either more cost-effective than selecting an application-specific part or because
programmability offers custom functionality not otherwise available.Embedded Systems
Interfacing for Engineers using the Freescale HCS08 Microcontroller is a two-part book intended
to provide an introduction to hardware and software interfacing for engineers. Building from a
comprehensive introduction of fundamental computing concepts the book suitable for a first
course in computer organization for electrical or computer engineering students with a minimal
background in digital logic and programming. In addition this book can be valuable as a
reference for engineers new to the Freescale HCS08 family of microcontrollers. The HCS08
processor architecture used in the book is relatively simple to learn powerful enough to apply
towards a wide-range of interfacing tasks and accommodates breadboard prototyping in a
laboratory using freely available and low-cost tools.In Part II: Digital and Analog Hardware
Interfacing hardware and software interfacing concepts are introduced. The emphasis of this
work is on good hardware and software engineering design principles. Device drivers are
developed illustrating the use of general-purpose and special-purpose digital I O interfaces
analog interfaces serial interfaces and real-time I O processing. The hardware side of each
interface is described and electrical specifications and related issues are considered. The
first part of the book provides the programming skills necessary to implement the software in
this part.Table of Contents: Introduction to the MC9S08QG4 8 Hardware Analog Input Serial
