FPIDroidHouse with a Nexys 3

As smart homes are becoming more and more de rigueur, Instructables user skorpyon1992 created a timely project, the FPiDroid House. This project is still in beta testing, but has shown a lot of potential so far. By using the Nexys 3 (or any of our FPGA boards), you too could connect a lot of your devices to monitor and control your very own smart home.

I2C in LabVIEW

I recently published an Instructable on how to use I2C in LabVIEW using LabVIEW MakerHub LINX, chipKIT WF32, and PmodGYRO as an example. Digilent sells a both LabVIEW Home Bundle and chipKIT WF32 in the LabVIEW Physical Computing Kit. In this Instructable, I go over how to read the data sheet to find what you’re looking for and how exactly to code what you find. This guide also details how to set up pull-up resistors for successful I2C communication.

What Is JTAG?

When perusing our site, you’ve probably noticed the section entitled programming solutions, or looked through our FPGA (field programmable gate array) boards and seen the acronym JTAG (Joint Test Action Group). …

Creating Custom Sounds

A little while ago, you likely saw the post that I did on my Color Invaders project. It’s a lot of fun to play as is, but it was suggested that the game could be made even better if there were some sound effects included as well. I got it done with a few tweaks…

Color/Colour Invaders!

I was recently inspired to try out by Hamster’s own ​Colour Invaders project. As the name suggests, this project is similar in design to the classic Space Invaders game or (more similarly) the ​Casio’s Number Invaders on the calculator. The idea behind the game is that different colored “invaders” start marching down the LED strip and you have to fire missiles that match the color of the oncoming invader. Naturally, as you successfully destroy more of the attackers, the faster they come towards your base. Here is what you need to get started.

Working with the Digilent Forum

As most of you know, we have our own Forum where anybody can go post questions and projects involving Digilent products: FPGAs, microcontrollers, any of our scopes, National Instruments products like the LabVIEW Home Bundle, Pmods, programming solutions, you name it. With this wide variety of products and an even wider variety of potential questions, the Forum can be a little daunting to navigate. This post will help first-time Digilent Forum users get the best experience out of the Digilent Forum.

Soda Can Theremin Video

We recently published a video about a simple Theremin built using the Analog Discovery and the Analog Parts Kit. A Theremin is an electronic musical instrument which essentially turns the user into a variable capacitor. The user can then adjust the frequency of the sound produced by the instrument by moving their hand in relation to an antenna. As the distance to the antenna changes, the capacitance also changes, thus changing the signal frequency. In the Theremin showcased in this video, a recycled soda can is used as the antenna.

Building Logic Gates with Transistors

This is a continuation of previous blogs about logic gates. Earlier you read about logic gates and their functions. Then you read about how to code logic gates in Verilog, VHDL, and C. Now its time to learn about creating logic gates with transistors. After reading all of these posts you’ll have learned about logic gate theory, coding logic gates in both hardware and software, and the physical hardware design of logic gates.
