Using the System

Table 3.2 Pin Assignment for Audio CODEC

3-6

Using the LEDs and Switches

The DE2 Board provides 4 push buttons. All of the buttons are Schmitt Trigger

de-bounced. When a push button is pressed, only one zero pulse will be generated.

There are also 18 toggle switches on the DE2 boards for users to set HIGH/LOW to

the 18 GPIOs of the CycloneII FPGA. The DE2 Board has 9 green user LEDs and 18

red user LEDs. Figure 3.8 shows the related schematics. The pin assignments of the

push buttons, DPDT switches, and LEDs are listed in Table 3.3, 3.4, and 3.5,

respectively.
