There are 27 user-controllable LEDs on the DE2-115 board. Eighteen red LEDs are situated above
the 18 Slide switches, and eight green LEDs are found above the push-button switches (the 9th
green LED is in the middle of the 7-segment displays). Each LED is driven directly by a pin on the
Cyclone IV E FPGA; driving its associated pin to a high logic level turns the LED on, and driving
the pin low turns it off.
A list of the pin names on the Cyclone IV E FPGA that are connected to the slide switches is given
