Virtual Touchscreen Game Using ZYBO

One of the really cool projects to come out of the Digilent Design Contest is a virtual touchscreen game hands-on tutorial for the ZYBO. This Instructable provides step-by-step instructions for customizing hardware to emulate a touchscreen on a simple TFT (thin-film transistor) monitor using camera and finger detection

Kirchhoff’s Circuit Laws

In one of my first circuits courses, the professor’s favorite words of advice were to “keep calm and remember KCL, KVL, and Ohm’s law.” With these three concepts, just about any electrical circuit can be analyzed and understood. Granted, things get a little more complicated when you add concepts like inductance and capacitance, but KCL, KVL, and Ohm’s law form the foundation of all circuit analysis. Brandon mentioned Ohm’s law in his blog post on how to choose a resistor for your design, so I will only be discussing KCL and KVL.

Remotely Control FM Radio with a chipKIT uC32 and Basic I/O Shield

Recently, a user of our products posted a tutorial about using a chipKIT uC32 to remotely control an FM Radio. We always love to see our users creating cool projects and try to give space here not only to projects created by us at Digilent but also by you the user. This project does require the use of multiple components and could be a bit overwhelming to a beginner, but we encourage you to try it out if you so choose!

Getting to Know the Electronics Explorer Board

One of our lesser known products that definitely deserves some more attention is the Electronics ExplorerTM Board. This is an incredible piece of hardware that everyone interested in electronics should have. When I first started in electronics, I used the popular Analog Discovery. After using the EE Board, another analog design product offered by Digilent, it has become my new favorite.

Interrupts vs. Polling: What’s the Dif-(Interrupt)-ference?

For those of you that have been coding for awhile, you likely have heard about both interrupts and polling. These are both techniques that can be used to alert your system board, such as a chipKIT microcontroller, when an input has occurred. But what is the difference between these two methods? Is one better than the other? Let’s find out.

Fun With the Project Box

We all know how much of a hassle it can be to safely transport your electronics, and let’s face it, the protective cases that many of our boards previously came in were flimsy, unaccommodating, and caused a great deal of stress for our customers. Well, we’ve responded to all of your feedback and I’m here to talk about our new Project Boxes!

How Do I Use Digilent Products at School? (Digital Edition)

As you learned from my previous post (the Analog Edition version of this post), we used the Analog Parts Kit and Analog Discovery in EE352 at Washington State University (WSU) to make an AM radio transmitter and receiver. Not only do we use Digilent products in EE352, but we also used Digilent parts in EE324 (Fundamentals of Digital Systems) — the digital lab class I was taking.

A Listening Calculator

When working with microcontrollers, it’s pretty straightforward to have your system board “listen” for an input that you would give it and have it do some sort of action to show that it noticed your input, such as pressing a button to light up an LED. Listening to a set of inputs and then comparing them to a predetermined set, like in the Simon Says game, is a little more involved but definitely doable. But what if we did not compare to any internal values and the system board has no idea how many inputs we might provide?

Running 5+ Servos on a uC32…Can I Do It?

In the not too distant past, we made a couple of posts on Pmods that can help drive motors as well as a post on stepper motors. Today, we’re going to check out running multiple servo motors on a chipKIT board. Why would we want to do this? Well, aside from the nice feeling that comes from successfully doing some extreme multitasking, we’d also be able to run some super cool mechatronics projects, such as a robot arm!

What Are Muxes and Demuxes?

A huge part of FPGA design is using logic blocks in design. With logic blocks, you can compartmentalize your design, rather than trying implement everything in one shot. Designing without smaller blocks would be like trying to design a car without subsystems like the braking system or engine. About half of the way through the course there is a project that covers a variety of basic logic blocks, including multiplexers (muxes) and demultiplexers (demuxes). So what are muxes and demuxes?

How to Read a Datasheet

Here at Digilent we have a ton of products with a large amount of documentation and examples (like our Learn site and our Instructables page) letting you know how you can use our products. Within all of these, there are statements about what each product is (and is not) capable of in addition to the recommended operating condition. Some of you may be wondering, “How do we know these things?” Much of the information presented is determined from a datasheet. But where do we find this sort of information in the datasheet, or how do we even read a datasheet? Let’s find out.
