Too often when performing control experiments more time is spent designing the hardware than concentrating on the subtle aspects of control theory. Our project provides the hardware necessary to control a wide variety of different systems. The hardware on our board is controlled by a 6809 microprocessor, and has 8K bytes of EPROM and RAM each. The board also has a serial interface which allows code to be directly downloaded from a PC. Other features include digital I/0, A/D, D/A, frequency input, variable duty cycle square wave, and line voltage control.
