ABSTRACT

In this paper, we study the light pen emulator implementation that can be used in industrialcomputer. For use in industrial control field, an input device of an industrial machine is anelectronic pen is usually used, but now many cases, a light pen cannot be used to the computer. In this study, the light pen emulator to substitute for the function that is available to theperipheral device on the PC, now. So we want to increase the utilization of industrial computer inthis research. The light pen emulator was designed by USB HOST, CPLD and MPU. Light pen signal, after interpret the input from the touch screen and mouse and USB system data, wasoutput by calculating screen coordinates. As a result, we showed that it is possible to use the computer in a variety of industrial devicessuch as a mouse, digitizer, touch screen, stylus, and designed emulator.
