Utilizing A Pci Daq Board In The Laboratory Course Of Microprocessor Systems And Interfacing

This paper describes five experiments using a PCI DAQ board in the laboratory course of “Microprocessor Systems and Interfacing.” The five experiments involve basic digital input/output interfacing design using a 82C55, analog-to-digital (A/D) and digital-to-analog (D/A) design. The PCI DAQ board chosen is PCI DAS-1002, manufactured by Measurement Computing 1 . Based on this PCI DAQ board, five experiments were designed, including I/O interfacing design, programmable DC motor speed control system design using pulse width modulation (PWM), and A/D and D/A interfacing design. These five experiments were carried out by three groups of students in the fall of 2005, 2006 and 2007. At the end of fall 2007, a survey was conducted among the students to assess these five experiments. The assessment results are presented in this paper.
