Test Your Dec to Bin Conversion Skills with Your FPGA

Hello FPGA enthusiasts! Today’s project takes you back to school where you learned the binary system. The author has designed a decimal to binary conversion game using FPGA. It is time to see if you did pay attention in class! The game uses a random number generator which generates any number between 0 and 255. Using the 8 switches on the FPGA, the player needs to guess the binary value right, following which the LEDs glow green. If you do go wrong, the LED matrix glows red showing you guessed incorrectly.

The FPGA board used for this project is the Nexys2 (you may need to adapt yours). It has an LED display, 8 switches and 8 LEDs which are perfectly suited for this project. Besides this some PMOD connectors, an 8×8 LED matrix, resistors, wires, daisy chain wires and 2 breadboards are the other hardware required. Steps 3, 4 and 5 of the project deals with understanding and connecting the hardware used for the project. Since the FPGA has a set of switches and a display, the extra hardware required is less for this project.

The programming language used by the author is VHDL. The program to run on the FPGA is available in step 9 as a zip file. The code has been broken down into modules for ease of understanding. Assigning the pins has been explained in detail in step 10, and the process of creating the bit file to run on the FPGA has been explained in step 11.
