USB 10-digit Seven Segment Display Module

by Dilshan R Jayakody:

This project is about an open-source, USB based, 10 digit seven segment display unit. This unit is specifically designed to work with POS systems and banking applications. Initially, this system is developed to work with PC based POS systems, and later it was modified to work with other applications.

To simplify the communication interface this unit is designed to emulate a COM port in the host terminal. Because of this feature, this module can work with many systems without having any additional device driver(s).

To extend the scope of this unit, it also comes with an option to switch between “direct mode” and “API mode”. In “direct mode” application or host device can directly send characters to the display unit over the emulated serial communication channel.
