Introduction FPGA stands for field programmable gate array. That mouthful is simply trying to tell you that you can program an FPGA over and over (field programmable) and that it is more or less just a large array of logic gates (gate array). Unless you already know what all that means, it is still not very helpful, so let’s break it down a little more. An FPGA belongs to a family of devices known as programmable logic devices.

These devices allow you to design a digital circuit, and the device will become that circuit. This works by configuring small blocks (known as slices) to perform logic functions and connecting them together to implement your larger design. A more detailed description of how this all works is covered later. You can reconfigure the FPGA as many times as you want, and each time it will become the new circuit without needing to physically change anything! In this chapter, we will explain a little more about what FPGAs are and what they are good at. We will also walk you through all the steps to set up the necessary software on Windows or Linux. Unfortunately, Macs are not supported by Xilinx’s tools, but you can work through a virtual machine running a compatible operating system. You can do with this with and, both of which are free. With a working environment, we will work through a basic project that will turn on an LED when a button is pressed. The Mojo The Mojo also has an Arduino-compatible microcontroller whose main function is to program the FPGA over USB. However, once the FPGA is programmed, the microcontroller can be used as an ADC (eight analog inputs are broken out) and a USB-to-serial interface for your FPGA designs. Beyond the other bare necessities such as a 50 MHz oscillator, the Mojo features eight LEDs and a button (commonly used as a reset). The I/O on the Mojo is all at 3.3 V and is not 5 V tolerant. Power can be supplied via the USB port, the barrel jack, the two holes, or the RAW input on the large headers. The supplied power should be between 4.8 V–12 V, with 5 V being the recommended voltage. You can connect an external power supply and the USB port at the same time, as the USB port is protected by a diode. You can find more information and order the Mojo from. The IO Shield, shown in is an add-on board that stacks on top of the Mojo. It features 4 7-segment LED digits (like the display on your microwave), 24 LEDs, 24 switches, and 5 buttons. It is a great board for working through example projects. You can find more information and order your own from. FPGAs Versus Microcontrollers: A Comparison FPGAs and microcontrollers are often compared. This is especially true for people coming from a background of working with boards such as the Arduino or Raspberry Pi. An analogy that I particularly like is to think of a microcontroller as a person. People are flexible. You can teach someone to do almost any task, and his arms and hands are capable of manipulating basically anything.
