Interfacing an 8085-Based Microcontroller: A Practical Approach to Developing Computer Applications Skills

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
