VGA Card

A graphics controller using Nexys 2 FPGA with ability to display images on a VGA interfaced screen. A python script takes in an image as input and gives out the timing vs pixel RGB values for displaying the image on the screen.

How it Works

A detailed explanation on how the card works can be found in our project report written as an IEEE styled paper (link).

Features

• Max Resolution: 800x600
• Max Refresh Rate: 50MHz

Technologies used

• Verilog
• Python (for generating PixelMap)
• Xilinx
• Cadence
• Digilent Adept

Usage

• Use the Python scripts to generate the intermediary verilog files
• Open the existing VGA ISE project, or create a new project and add the following files to it:
  • The generated verilog file
  • vga_card_constraints.ucf(The constraints file)
• Generate the bit file for the FPGA board being used
• Connect the VGA cable to the monitor and board
• Dump the generated bit file onto the board using Digilent Adept
