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 Pulse width modulation to send other values to a wire,…

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 thanks to the awesome customer support from Justin at Embedded…

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. The biggest challenge I had with it was converting the…

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 reversible counter, but no one had created a part for…

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 to make a reversible slow counter that lets you choose…
