The main purpose of this lab, past the initial setup and tour around the software, is to create an output using the seven segment displays on the Digilent Nexys2 FPGA. The first part of the lab, LED Decoder, walks the user/group through running a program to output different numbers on the displays, using the buttons and switches to change the number. The image below shows the first program running, with the first and third switches toggled on, producing the number 5.
