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.
