Strange VGA Effects on an FPGA

When I assembled my VGA implementation on my Mojo FPGA, I did so with only a single wire for each of the color signals (Red, Green, and Blue). This limited my color choices to 8 colors. I read about using…

A Saturday morning puzzle on my FPGA

I woke up this morning with a desire to solve a puzzle. I decided that I'd make a simple LED chaser on a 7-segment LED display using my Mojo FPGA (now that I have everything working in Windows 10 again…

Pong on the Mojo Revisited

In my previous post, I briefly discussed the implementation of a pseudo-pong game on my Mojo FPGA developer board. I was able to implement the VHDL version that I linked to later in the post and it works much better.…

Creating PONG on the Mojo FPGA

I recently found an old VGA monitor on the side of the road and it inspired me to see if I could get my Mojo FPGA board to output a VGA signal. I took the monitor apart and wired its…

Custom Fritzing part for Mojo v3

There is a great tool called Fritzing that allows you to create a breadboard view of circuits that you can use for documentation. I really wanted to use it to document the breadboard for my post on setting up a…

Using Notepad++ as the default editor for Xilinx ISE

I was having difficulties working with the built in text editor for the ISE FPGA tool from Xilinx. I was missing some of the things I've come to depend on in the editors that I use every day (Visual Studio,…

Reversible Binary Counter on the Mojo FPGA

After playing around with the Binary counter implementation from a previous post: Implementing a simple binary counter in the Mojo FPGA IDE, I wanted to make the LEDs display a count down in response to a switch position. I decided…

How I accidentally learned something unexpected from a simple binary counter

In my previous post, I talked about how I implemented a binary counter with my Mojo FPGA board. I am working on a follow-up post on implementing a reverse binary counter with a switch that lets you change between the…

I have been a computer nerd since I was ten years old. I begged my parents to buy me a computer for Christmas. In 1982, I was the proud owner of a Texas Instruments TI-99/4A. I've been coding since.
