Experiment of Measurement and Control using Embedded System for Undergraduate Students

In the department of computer science and electrical engineering (CSEE), Kumamoto university, a series of student experiments are prepared for 2nd and 3rd graders. In the technical educations, experiments about the computer science and electrical engineering are important to study the engineering comprehensively. In experiment I, 2nd graders study the fundamental treatment of measurement equipments, behaviors of major devices and technical writing of engineering reports. In experiment II, 3rd graders study technical issues about computer science and electrical engineering in more detail.This paper concerns the experimental program entitled “measurement and control using embedded system” in experiment II for 3rd graders. The purpose of this experiment is to design a simple PID controller on the micro control units (Lenesas M16C/26 MCU). To implement the PID controller, students program the software functions step by step, e.g. PWM signal generation using interrupted handling, encoder counter using the event timer. The detail of experimental program using embedded system is explained in this paper.
