Interfacing To Microprocessors And Microcomputers

Microprocessor Interfacing provides the coverage of the Business and Technician Education Council level NIII unit in Microprocessor Interfacing (syllabus U86/335). Composed of seven chapters, the book explains the foundation in microprocessor interfacing techniques in hardware and software that can be used for problem identification and solving. The book focuses on the 6502, Z80, and 6800/02 microprocessor families. The technique starts with signal conditioning, filtering, and cleaning before the signal can be processed. The signal conversion, from analog to digital or vice versa, is explained to answer why conversion is necessary for the microcomputer or processor. The types of analogue to digital converter, voltage measurements, scaling, and interfacing with ADC to a microcomputer are all taken into account. After the signal has been converted into readable data, the date transfer techniques are described. For data between systems and subsystems to be efficient, the timing, electrical, I/O lines, serial data, and bus structure should be considered. A more detailed explanation of parallel I/O controllers as applied to Z80 PIO and the 6821 PIA follows. For serial I/O controllers, the serial data transfers, speed in baud rate, software routines, and ASCII codes are all examined. Finally, the dedicated I/O controllers involving keyboard encoding, the ASCII (QWERTY) keyboard interface, the visual display unit, cathode ray tube controller devices, and the drive controllers are discussed, as each of these requires one specific application. This book is useful for computer engineers, software engineers, computer technicians, teachers, and instructors in the field of computing learning. This text can also be an informative reading for those have great interest in computer hardware.

This textbook for students explains the general functions of computer hardware and software in a scientific environment, from computer programming to the operation of different types of equipment. It concludes with a series of experiments to illustrate the behaviour of various systems.

Integrates the information necessary to conceptualize, select, mate and match, build, and interface microcomputer systems to most applications.

This comprehensive and thoroughly updated text now in its second edition continues to provide the complete knowledge about the Intel's 8085 microprocessors, its programming and concept of interfacing of memory, input/output devices and programmable peripheral chips. Organized in four parts, Part I (Chapters 1-9) covers a review of the analog and digital signals as well as hardware and software related aspects of microprocessor 8085. Part II (Chapters 10 and 11) discusses memory and input-output concepts, analog to digital and digital to analog converters and various memory and IO address decoding techniques. Part III (Chapters 12-17) explains the programmable interfacing chips with extensive interfacing examples. Part IV (Chapters 18 and 19) presents a brief discussion on other 8-bit microprocessors along with 16 and 32-bit Intel Processors. Each topic has been supported with numerous examples that will help students apply the concepts to other microprocessors in the course at advanced level. This book is designed specifically for the undergraduate students of electronics and communication engineering, computer science and engineering, and information technology. New to this Edition: Chapters on "Architecture and Organization of Microprocessor" and "Instruction Set of 8085 Microprocessor" have been revised and modified substantially. Multiple choice questions have been added to all the chapters.
