THE 2X6 PIN CABLE TO DUAL SIX-PIN CABLE.
One of the best ways for an adventurous programmer
to test their coding chops is with the menagerie of Pmods
available from Digilent. Pmods are Digilent’s brand of
peripheral modules. The Pmods are compact I/O interface
boards meant to add functionality to the I/O Explorer and
other Digilent boards. We had the opportunity to test out a
delightful variety of Pmods, many of which could be
implemented by sample programs in the SDK.
One of the most basic Pmods is the eight LED Pmod.
The simple unit contains exactly what you would expect –
eight small LEDs arranged in a row. Turning LEDs on and
off can make for an amusing light show, but what they’re
really useful for is debugging. Coordinating LED flashes with
input from other sensors is a great way to see that your
sensors are working properly. Sure, you can add
printed messages to the output window of your
application, but flashing LEDs are an exciting
and visual representation of your sensor inputs.
The eight LED Pmod even has its own sample
program included in the Adept SDK.
