Indian Lab Suppliers supplies the Running Message Display (Product ID: 13154) as part of its electronics engineering lab equipment range. It is a PC-interfacing experiment in which a text message scrolls across an LED display under C program control.
Quick Answer
Students build a character table and shift the displayed columns one step at a time so the message appears to move across the display, all sent from the PC parallel port. Editing the text and the step delay changes the message and its scrolling speed. The module works with the Computer Interface Trainer, which supplies the 25-pin parallel link and power. Please confirm the display size and whether the base trainer is included at quotation.
