LED Pin List
Table 2–12 lists the FPGA pins assigned to the LEDs.
Seven-Segment Displays
The development board provides four adjacent 7-segment displays,
HEX0–HEX3
, ( Figure 2–16 ) for reporting numerical values from the
FPGA. Each segment connects to an FPGA general-purpose I/O pin. A
LOW logic level applied at the pin lights up the segment; a HIGH logic
level turns the segment off.
