Need a Boost?

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.

Back to Basics with Transistors

With any upcoming projects you may be doing, will you be using transistors? A few months ago, Brandon wrote a post detailing the basics of transistors — what they are, how they work, how they can be used, etc.

History of the FPGA

As you probably know, one of Digilent’s major focuses is producing FPGA (field programmable gate array) boards and educating the public on FPGA design. One of the classes I was in last semester focused on FGPA design. This class is EE324 at WSU, which is taught by Digilent’s own Clint Cole. He gave a background lecture on the History of FPGA chips. Not only was it an extremely interesting lecture, but it also helped me understand the huge leaps in logic design that have been made since the 1960s. This is the history that led to the development of FPGA chips. The chips are the parts that Xilinx makes that we use on our FPGA boards.
