Demystifying the Linux Kernel: Diagram & Core
You’ll often hear about the “Linux kernel”, but what does that mean? Today we’re going to go about explaining what the Linux kernel is in terms that people can understand.
New Video Alert: Pmod Monthly Episode 2
What are some of the communication protocols commonly used in Digilent Pmods? Find out by watching our latest video, featuring James Colvin.
Throwback Thursday: Digilent’s First Video
While Digilent’s YouTube channel now has x videos, but it wasn’t always that way. Back in 2010, we did our first YouTube video. It’s part of the Real Analog Course by Tim Hanshaw, and it’s incredibly fun to see how much has changed in five years!
Digilent Forum Update
On May 1, our forum was offline for a major version update of our forum software. You probably noticed that the site looks very different than it did before! The upgrade went smoothly and we are excited to share the new features with you.
KCL & KVL: Understanding 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.
Making an FPGA Composer
What are some more things to do with an FPGA? One Instructables user, krosenfeld7, made a guide for an FPGA composer.
Throwback Thursday: Looking Back at Nexys
We’ve talked a lot lately about the Nexys 4 DDR lately, and we definitely hope you like it as much as we do here at Digilent. But what are the roots of this awesome board?
Adam Taylor’s MicroZed Chronicles: Working with other Zynq-Based Boards
Over at the Xilinx blog (the excellent Xcell Daily Blog), Adam Taylor reviewed his experience working with some of the Zynq-based boards. One of those reviews is for the ZYBO. …
New Product — the PmodMIC3
We have a new member of the Pmod family — our latest addition is the PmodMIC3. The Digilent PmodMIC3 is a small microphone module with a digital interface. An improvement …
Understanding Gigabyte: How Much is One GB of Memory?
We hear words like gigabyte (GB) and terabyte thrown around a lot, but what can we actually do with that much memory? At the most basic level of computing, we have bits, which are going to be either a 1 or 0. A byte is 8 bits. We’re going to represent a byte as a dot.
Throwback Thursday: Early Digilent Packaging
When Norm MacDonald started working full-time for Digilent back in 2005 – 2006, most of our products were sold in very basic packaging (think anti-static bags and plain white boxes). Totally understandable for a starting company. A few boards were given a bit of branding, though. The Basys and Nexys, of course. These were the simple boxes those came in at the time. (They may have been done by Clint or Jim or some combination of the two.)
Tic-Tac-Toe with FPGAs
Who doesn’t love the classic game of tic-tac-toe? And now it can be made new and fresh with the Nexys 2 FPGA board!
Libraries
This week happens to be National Library week, and although Digilent is not a library, we certainly use them! I’m not referring to public libraries, though (although I am personally a fan of them); rather, I’m talking about the C++ libraries that are widely used with our microcontrollers. Although C++ libraries are not quite the same as an IP for FPGAs, they serve a similar purpose. These libraries include a set of predefined functions that perform a specific task, such as sending and receiving a set of data over SPI, that the user can use without having to define what they do.
The (Ultimate) ZYBOt Guide
Back in March, we released a blog post announcing the ZYBOt. There was a set of Instructables and a video showing what the ZYBOt is all about. If you check those out, you can see that the ZYBOt is remote-controlled and has a video feed that can be displayed to a computer. The ZYBOt is a great project for people that want to dive into working with FPGAs and Linux.
Turbo Strikes Back
In a contest between robot and human…the robot won (at least this round). Breaking one of Asimov’s Laws of Robotics, our normally friendly Turbo managed to get in a hit at one of our interns last week when she was troubleshooting.
Throwback Thursday: The Original Cerebot Line
You’re probably familiar with our chipKIT Pro MX7 and MX4 by now. But how did this line of microcontrollers get its start?
What Are Arrays, Again?
Back in August, one of our interns told us why arrays aren’t actually very frightening. However, if you’re anything like me, that information might have…slipped. So I decided to take another look at arrays!
Projects Using the Analog Discovery
Are you looking for a good project to do with your Analog Discovery? On the Digilent Forum, Alex loaded a few of them from students at Sri Vishnu Engineering College for Women in southeastern India.
Integrated Circuits in Digilent Products
We’re going to look at integrated circuits, specifically the integrated circuit in the chipKIT MAX32.
Learning the AI behind Amazon
How does Amazon improve its customer service? It uses an AI to learn user preferences (by tracking purchases) and generate recommendations. This is an AI that learns over time. And now Amazon is making one of its algorithms available for programmers and other businesses to use.
Aleph 1.0, the Internet-Controlled Microscope Robotic Manipulator
Aleph 1.0 is a remote-controlled robotic manipulator for biological or chemical probes. Its purpose is to allow scientists to safely manipulate and analyze biohazardous or toxic substances, or to simply observe or interact with small probes and/or devices that must be contained in controlled environments. Instructables user kovari_andrei provides a tutorial for doing just that. It uses the chipKIT Pro MX7, and we’re thrilled to see our products being used in such cool ways.
What Instructors Want from Labs
In a Wired magazine article, physics professor Rhett Allain answers some of the questions he gets from students about what he’s looking for in the lab.
Digilent Software Solutions: What They Are & How to Use Them / Digilent USB Scopes, Analyzers, Generators: Info & Use Cases
Basic Waveform Measurement and Display
If you or anyone you know is learning the basics of electronics one of the things they’ll have to figure out is basic testing and measurement. We have a great project on the Learn site that can introduce one to basic waveform measurement and display with the help of the Analog Discovery.
Throwback Thursday: Digilab Begins
A few weeks ago, we did a throwback that included the D2XL. And now we can take a look back at the original Digilab I! It’s one of the first boards we made (circa 2001), and it’s always interesting to see how far we’ve come.
