4.4.3. The GPIO Tab
The GPIO tab allows you to interact with all the general purpose user I/O components on your board. You can read DIP switch settings, turn LEDs on or off, and detect push button presses.
Figure 12. The GPIO Tab

User DIP Switch | Displays the current positions of the switches in the user DIP switch bank (SW2). Change the switches on the board to see the graphical display change accordingly. |
User LEDs | Displays the current state of the user LEDs for the FPGA. To toggle the board LEDs, click one of the LED [ 0 to 3] buttons to toggle the 4 green LEDs, or click the All button. |
Push Button Switches | Read-only control displays the current state of the board user push buttons. Press a push button on the board to see the graphical display change accordingly. |
