February 2011 Altera Corporation Arria II GX FPGA Development Kit User Guide
The GPIO Tab
The GPIO tab allows you to interact with all the general purpose user I/O
components on your board. You can write to the LCD, read DIP switch settings, turn
LEDs on or off, and detect push button presses. Figure 6–3 shows the GPIO tab.
The following sections describe the controls on the GPIO tab.
LCD
This control allows you to display text strings on the character LCD on your board.
Type text in the text boxes and then click Write.
1 If you exceed the 16 character display limit on either line, a warning message appears.
User Dipswitch
This read-only control 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.
