Instrumentation for Embedded Control Systems Design: Incorporating the Digilent Electronics Explorer BoardAbstractAuburn University’s Electrical and Computer Engineering curricula include a junior-year,laboratory-intensive course on embedded control systems design. Teams of students design,implement, test, evaluate, and report on a microcontroller-based embedded control system thatincludes both analog and digital electronic elements. The laboratory infrastructure for thiscourse is built around the Digilent, Inc. Electronics Explorer board (EE board), which is anintegrated analog and digital circuit design station.In this paper, the authors present how the EE board, and PC-based “Waveforms” software meetthe instrumentation needs of the course, and enhance the students’ abilities to effectivelycommunicate their work. The paper will be organized as follows: 1. Present an overview of the course objectives, and describe how these are related to the overall student outcomes of the Electrical and Computer Engineering programs. 2. A typical embedded control system project is presented, highlighting several design options for the analog and digital subsystems. 3. After the above background is presented, the instrumentation needs of the laboratory are explained. Discussion will also include some infrastructure maintenance considerations. 4. Salient features of the EE board are reviewed and compared to the laboratory infrastructure that had been used previously. The presentation will also cover other laboratory infrastructure that is being used in a complementary manner to build a complete, powerful design workstation environment. 5. The authors explain how the EE board and Waveforms software are used in several of the weekly laboratory exercises to measure and record system performance. Examples of virtual instrumentation usage and data presented in students’ reports and presentations will be described. 6. Students are also introduced to a few practical issues and limitations of instrumentation in this course. Therefore, some learning objectives related to software-based virtual instrumentation are also presented.
