DE1 User Manual
4.3 Using the 7-segment Displays
The DE1 Board has four 7-segment displays. These displays are arranged into a group of four, with
the intent of displaying numbers of various sizes. As indicated in the schematic in Figure 4.6, the
seven segments are connected to pins on the Cyclone II FPGA. Applying a low logic level to a
segment causes it to light 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
4.7. Note that the dot in each display is unconnected and cannot be used. Table 4.4 shows the
assignments of FPGA pins to the 7-segment displays.
