Table 2–28 lists the HSMC user-defined LED schematic signal names and their
corresponding Stratix IV E FPGA pin numbers.
Table 2–29 lists the HSMC user-defined LED component reference and the
manufacturing information.
Seven-Segment LED Display
The development board includes one quad digit seven-segment LED display. The
display is controlled by the Stratix IV E FPGA device. Each segment of the display can
be illuminated by driving a logic 0 to the connected device's I/O pin.
Table 2–30 summarizes the display segments and pin assignments for the
seven-segment LED display.
