As we continue on with our Pmod series featuring one of Digilent’s largest product lines, we find ourselves needing to see what’s going on inside of our microcontrollers and FPGAs as they race through their code at 80,000,000 times a second (or even faster!). Once again, Digilent has a variety of solutions to solve our dilemma. Our visual Pmods range from simple LEDs and a seven-segment display (SSD) to complex OLED and LCD screens.

You may recall a post we had a few days back on the Pmods that offered a DAC. As I mentioned then, DACs are used for a wide variety of applications but one of the most common ways that you see a DAC being used is in audio applications. Digilent’s Pmod line offers several audio peripheral modules that do just that.

Previously, we had the chance to take a look at the LS1, which is a great Pmod to use with line-following robots such as Susan. Today, we’ll take a look at five of the digital-to-analog converter (DAC) Pmods. Four of them are conveniently named DA1, DA2, DA3, and DA4, and the last one is a R-2R circuit.

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.

In this month’s edition of Electronics Design Magazine, a rather nice article calling out both our new ZYBO processor board and our Pmods™ was written. Bill Wong, the article’s author, discusses many of the user experience improvements that Xlinx has made in regards to their latest Zynq-7000 multi-core, ARM A9+FPGA processor. In those improvements he mentions both our newest ZYBO board and our Pmods™!
