The DE0-CV board has six 7-segment displays. These displays are paired to display numbers in
various sizes.
Figure 3-9
shows the connection of seven segments (common anode) to pins on
Cyclone V FPGA. The segment can be turned on or off by applying a low logic level or high logic
level from the FPGA, respectively.
Each segment in a display is indexed from 0 to 6, with corresponding positions given in
Figure 3-9
.
Table 3-5
shows the pin assignment of FPGA to the 7-segment displays.
