Using Karnough’s map, logic circuitry for each input to the display is designed. The logic circuit is designed with 4 inputs and 7 outputs, each representing an input to the display IC. The basic idea involves driving a common cathode 7-segment LED display using combinational logic circuit. Here we design a simple display decoder circuit using logic gates.Įven though commercial BCD to 7 segment decoders are available, designing a display decoder using logic gates may prove to be beneficial from economical as well as knowledge point of view.īack to top Principle of Display Decoder Circuit It generally has 4 input lines and 7 output lines. Mostly these displays are driven by the output stages of digital ICs (to which the visual indication of the output stages has to be performed) such as latches and decade counters, etc.īut these outputs are in the form of 4-bit binary coded decimal (BCD), and not suitable for directly driving the seven-segment displays.Ī display decoder is used to convert a BCD or a binary code into a 7 segment code. However to display the characters and numbers (in order to produce the decimal readout), seven-segment displays are most commonly used. Generally, LCD and LED segments provide the display output of numerical numbers and characters. Most often seven-segment displays are used to display the digits in digital watches, calculators, clocks, measuring instruments and digital counters, etc. Applications of Display Decoder Circuit.7 Segment Display Decoder Circuit Design.It's a small step towards making FPGA technology more accessible and user-friendly. This project not only demonstrates my Verilog skills but also showcases the creative and engaging ways technology can be utilized. ` A push button is used to reset the scrolling text to its initial positions. ` If we turn on the switch 2 it shows "ECE" message. ` If we turn on the switch 1 it shows "IITS" message. ` The module in default show's "HI" message. "display_output": The scrolling text displayed on Basys-3 7segment displays. "text_input": Input for your name or message. "clk": Clock signal for precise synchronization. Scrolling Text: The module smoothly scrolls names("HI","IIITS","ECE") or messages across the Basys-3 7 Segment displays.Ĭustomizable: Easily customize the text you want to display, making it ideal for showcasing various projects or announcements.Įye-catching: Grab attention with this eye-catching display that adds a professional touch to your projects.
