Good day FPGA Enthusiasts! FPGAs can be used for a versatile set of applications from real time engineering solutions to building funny games. Today’s post is going to focus on the latter where we build yet another game concept using a FPGA board (you may need to adapt your own). The game in consideration is a simple version of ‘Whack a Mole’. Since the FPGA already has a segment display, Switches and LEDs the peripherals required to run the game are minimum.
The only Hardware required for building this game (you may need more parts depending on your FPGA board) is a FPGA and 3 LEDs (2 of the same color preferably red and one different color preferably white or green). Since only 3 LEDs are being used, you can simply plug them right into the FPGA without using a breadboard or jumpers as shown by the author.
The entire project uses a simple architecture that houses 5 key components which are the LFSR, Score keeper, Clock divider, LED controller and the 7 segment display. Each component significance and working principle has been detailed by the author.
The coding has been done in simple modules and each module has been shared under the corresponding architectural component explanation. The coding language used is VHDL (.vhd) and the code is easy to follow and relate to.
Though the game is fun, there are a few bugs in the code which can be corrected to make the game truly addictive and perfect.
Whack down all those bugs and enjoy!
