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 character LCD, read DIP switch
settings, turn LEDs on or off, and detect push button presses.
Figure 6–4 shows the
GPIO tab.
The following sections describe the controls on the GPIO tab.
Character LCD and Display
