What do you use to connect your Pmods to their host boards? We now have two new options, the 6-pin Pmod Cable Kit and the 12-pin Pmod Cable Kit.
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
What are some of the communication protocols commonly used in Digilent Pmods? Find out by watching our latest video, featuring James Colvin.
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 …
It’s been awhile since we last had some specific focus on Pmods, so I decided that we should get back to our favorite blog series (or at least my favorite). This week we’re going to check out some of the Pmods that occasionally get overlooked– the power Pmods. These Pmods include screw terminal modules, transistor modules, and power monitors.
Some of the Pmods, such as the PmodOLED and the PmodCLP, need a higher operating voltage to run their screen than is normally supplied by system boards. This predicament could be solved by using an external power supply to power the screens, but that can get pretty inconvenient especially if you want your project to be portable. A slightly easier method that does not require a power supply is a boost converter circuit.
Robots that run around on motors are pretty sweet. These motors traditionally tend to be DC motors that are controlled through the use of an H-Bridge, which can change the flow of current so that the motor is able to run forwards or backwards. H-bridge modules, such as Digilent’s PmodHB3 or PmodHB5, also tend to have two pins labeled as Sensor A and Sensor B that measure which direction the motor is rotating. The two sensors, A and B, will be wired to the outputs of components known as Hall effect sensors. Unsurprisingly, these measure the Hall effect. But rather than having the “word in the definition” problem, let’s learn some of the practical details.
Recently I released a collection of projects going over how to use LAbVIEW, the chipKIT Max32, and the PmodACL to do some neat stuff with accelerometer data. These include filtering, multidimensional vector plots, and tilt measurement.
Recently, one of our hardworking interns started a new video series. You may have seen James’ blog series about Pmods. Now there’s a video component as well! James begins the series by introducing Pmods and talking about their history.
Happy Groundhog Day! At Digilent, we have Punxsutawney Sam the groundhog to tell us whether we’ll have more winter to look forward to. Our 3D-printed friend is here to tell us whether winter will wane!
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?
It’s time for another Pmod feature! Today, we’re going to check out the Connector Pmods. Rather than just being strictly limited to a pure input Pmod or pure output Pmod, all of these Pmods are able to easily communicate with the system board in both directions. Although many of these Pmods might be chalked up to simple “pass-through” modules, I certainly wouldn’t label them that way. These Pmods offer some invaluable features that are otherwise not so easily obtained.
At OTH Regensburg, Prof. Dr.-Ing. Heiko Unold has spent years finding new ways to connect engineering theory with hands-on experimentation. By integrating the Analog Discovery platform across multiple courses, he …
Field-programmable gate arrays (FPGAs) are digital devices. They can’t read a voltage directly. To bring an analog signal into an FPGA, you need an ADC, short for analog-to-digital converter. You …
