The DE2-115 Board has eight 7-segment displays. These displays are arranged into two pairs and a

group of four, behaving the intent of displaying numbers of various sizes. As indicated in the

schematic in Figure 4-10, the seven segments (common anode) are connected to pins on Cyclone

IV E FPGA. Applying a low logic level to a segment will light it up and applying a high logic level

turns it off.

Each segment in a display is identified by an index from 0 to 6, with the positions given in Figure

4-10. Table 4-4 shows the assignments of FPGA pins to the 7-segment displays.
