Development Board Components

Toggle Switch Pin List

Table 2–11 lists the FPGA pins assigned to the toggle switches.

Displays

The development board provides the following displays:

■ LEDs

■ Seven-segment displays

LEDs

The development board provides 18 user-controllable LEDs, 10 red LEDs,

LEDR0–LEDR9, above the toggle switches (Figure 2–13) and 8 green

LEDs, LEDG0–LEDG7, above the four push button switches

(Figure 2–10). Each LED connects directly to an FPGA general purpose

I/O pin. A HIGH logic level on a pin turns the LED on; a LOW logic level

on a pin turns the LED off.

LED Schematic

Figure 2–15 shows a schematic diagram of the LEDs.
