This script requires that Pmod KYPD be connected to the Analog Discovery DIO 
Pins in the following order (see folder for pinout):

DIO Pin	|	Pmod Pin
---------------------	
DIO-3	|	  1
DIO-2	|	  2
DIO-1	|	  3
DIO-0	|	  4
GND(↓) 	|	  5
V+   	|	  6
DIO-7	|	  7
DIO-6	|	  8
DIO-5	|	  9
DIO-4	|	  10


Once the connections are made, open the workspace in WaveForms. Press the Run 
button (or F5) in the Script window. The Script Output window will show the 
key presses as they're detected. The script is designed so that each time a 
key is pressed, only a single key press is registered. Use headphones or 
speakers to listen to the audio output.
