Some of you may have wished at one point that there was a way to conveniently keep track of a series of inputs that you are providing to your system. Luckily, an array is an excellent way to solve this predicament, and it has the added bonus of being easy to use!
We are going to continue with our Pmod series and talk about how you get the Pmod (peripheral module) to do what you want it to do. After all, it is not the best plan (especially in electronics) to just plug something in to a random spot and hope the device works correctly. The vast majority of the peripheral modules in the Pmod line collect or receive data (or both) and need to communicate this data with the host board. A GPS module that doesn’t send its coordinates to the host or an audio amplifier that does not receive data from the host are not terribly useful. Successful communication is key in any relationship, electronic or otherwise.
As you learned from James’ post, Digilent offers 63 Pmods! Each of those products has its own story of its conception and evolution. One of those products that had a very interesting beginning is the PmodLS1.
A few weeks ago while chatting with James (another intern) and Gene (our co-founder) we were discussing how the company began and how the board design process works. In this discussion we discovered that the Pmod LS1 has a beginning in education at Washington State University.
What is a Pmod? What does it take to become a Pmod? How did the Pmods come to be in the first place?
A good display is hard to find. So when I came across the Adafruit’s 1.8″ 18-bit color TFT LCD display with microSD card breakout I couldn’t wait to get it working on our chipKIT boards.
We have made a few posts showing off our 3D printers and some of the classes on 3D printing that we have done here at Digilent. Garrett Mace from macetech.com showed us some of the basics on how to use various 3D modeling software like AutoDesk Inventor, Autodesk 123D Design, OpenSCAD, MeshMixer, and SketchUp. Today, I’m going to introduce some of the basic modeling tools available in the free but robust Blender.
At Washington State University, the electrical engineering department uses Digilent FPGAs in several classes. Students are allowed to pick from a variety of our FPGAs. The main choice is between the Nexys or Basys lines of FPGAs. As a student, I hear a lot of confusion from students about the differences between the two series of boards. I figured that students can’t be the only ones who have questions about the difference, so I decided to write a quick summary of the differences. I’ll be using the Nexsys 4 and the soon-to-be newest member of the Basys series as an example. I’ve compiled two lists to highlight the differences between the two.
The Logic Analyzer instrument in WaveForms can be used to easily decode Manchester encoding signals. The following guide presents what Manchester encoding is, what are its advantages over unencoded digital …
Though oscilloscopes are most known for viewing and diagnosing analog signals, there are some cases where critical characteristics of digital signals can only be viewed on an oscilloscope. When designing …
Today we will go over a brief overview on FPGAs!
When looking at the oscilloscope feature of a multi-instrument device or when comparing two benchtop oscilloscopes, the first specifications that we look at are the bandwidth and sample rate. While these …
