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.
