Abstract

An array of 16-Segment LEDs are illuminated in a scrolling marquee sequence that is selected by the user. The software portion consists of a user interface in the form of a LabView application which sends digital outputs through a USB DAQ Device. A text string, and a specified number of trailing blank characters can be selected at the start. Once this data is submitted, the application will display the logic sequence of each segment, as well as allow for the speed of the scrolling text to be adjusted. The digital bit sequence for each corresponding segment is sent to a digital output as well as the clock signal to operate the 8 bit shift registers. Every shifted segment output is then sent through a resistor and then to their respective LED.
