Labs

Lab 1

This lab included code for a 4 digit hex display and counter. The first lab of the semester helped getting familiar with Vivado, as this was my first time utilizing the program to configure a FPGA board with specific code.

Lab 2

In this lab, I used the code provided to create a hex counter on the board. For this lab, I started testing the code with the NEXYS A7 then switched over to the A4 to see that both worked with keeping everything the same. I also ran into a little bit of trouble trying to boot from memory, but figured out that the Hardware Manager needs to be closed after the memory file has been booted onto the board. After figuring this out, Lab 2 taught me a good amount about booting from memory and the similarities between the two boards.

Lab 3

In this lab, I used the code provided to create a bouncing ball display where the FPGA device needed to be connected to a VGA monitor. At first, I had no luck with getting the display to appear on the screen I had the board connected to, but I actually found a VGA monitor at my house that worked.

Lab 4

In this lab, I used the code provided to create a hex calculator, the only problem that I ran into with this lab is that I do not have a keypad that is required to make the actual function work. I was still able to take away something although this program will not work unless I have access to the keypad.

Lab 5

In this lab, I used the code provided to create a DAC Siren, where there were parts in the Lab where I had to modify the code. The following changes in the code were the following:

Changed the upper and lower pitch limits along with the wailing speed
The tone module was modified to create a square wave instead of a triangle wave
The SW0 - SW7 switches on the board were utilized to set the wailing speed
Added a second wail instance to drive the right audio channel. Different high and low tone limits and wailing speed for the right audio channel.

Lab 6

In this lab, I used the code provided to create a Pong game on a VGA display. The following changes I made in the code were the following:

Utilized the slide switches on the Nexys 4 DDR to program the ball speed in a range of 1-32 pixels/frame. This helped visualize how the ball will work while in play.
Added a difficulty setting that made the paddle shrink by one pixel after each consecutive hit. The paddle will revert to original form once the ball is missed.
