In the Electronics Technology course – EE 445, students were directed to construct, troubleshoot, and interface an 8085-based microcontroller in order to control electromechanical circuits. This microprocessor, using Intel 8085A processor, was assembled from components and was interfaced to take full control of a stepper motor’s motion. In addition, the microprocessor’s application to generate and measure waveforms was examined. This manuscript attempts to describe the basic architecture of a microcontroller system, and examine its interfacing techniques as well as its applications in providing communication to the outside world.
The knowledge of computers and their applications has become a fundamental technical skills required of electronics engineering technology students. In order to provide students with an opportunity to develop microprocessor application skills, this course is focused on teaching programming and application of Motorola 68HC11-A8 microprocessor. Although students who have learned one type of microcontrollers in class can adapt without too much difficulty to other types, this usually takes a considerable time and effort and they may not afford the practice and learning of the function of other types of processors during their academic years of university study. On the other hand, the competitive labor market may require them to demonstrate skills on major types of microcontrollers such as Intel-based processors immediately after their graduation. In order to help students to develop a crosslinking skills so that they are able to work on at least two types of microcontrollers, i.e., Motorola and Intel, a senior project was integrated in the Computer Electronics course – EET 445. In this course, while a student is provided with the knowledge of Motorola microcontroller instruction set and interfacing in classroom and laboratory setting, he or she builds an 8085A-based microcomputer system as a major project from components.
