First FPGA Project - Getting Fancy with PWM

Contributors: Alchitry, Ell C

Introduction

When you first buy an Alchitry Au+, Alchitry Au, or Alchitry Cu board, the default FPGA configuration creates a fancy wave effect on the LEDs. In this tutorial we are going to walk through different steps for how to make something like this. It will be a great overview for how to approach a design and various things to consider given that we are working with hardware.

Let's dig in and see how all this works!

I’m going to assume you already have the tools setup and are working in Alchitry Labs using Lucid with an Alchitry Au or Cu. You should also have read the previous tutorial, Programming an FPGA, to get down some of the fundamentals.
