Dot Matrix Interface using FPGA

The Dot Matrix using FPGA board is a display system that uses an 8x8 matrix of LEDs to display text or simple graphics. The prototype utilizes Basys 3 FPGA Trainer board, which allows for flexible and efficient programming of the display system. It involves designing and implementing the hardware and software components of the display system, including the LED matrix driver circuit, FPGA board interface, and communication protocol. The hardware core is designed in Verilog, a hardware description language commonly used for FPGA programming. The 8x8 dot matrix is implemented using the 1088AS module which is interfaced with the FPGA to successfully run the system. A dot matrix cannot display the entire alphabet letter at once, so to display the letter in the form of 8x8 lines, the clock frequency of the proposed system is reduced to refresh all 8 columns 1000 times per second. The refresh rate of each column to display letters is 125 Hz. The completed proposed dot matrix display system will be a more secure, high-performance computing and cost-effective solution for displaying text and graphics. It can be useful in various applications, including signage, advertising, and information display purposes. This paper also demonstrates the use of FPGA technology where we can design a cost-effective system for the mass production of display boards than the embedded based solutions which are available in the market.
