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, write to the 7-segment display, load images to the
graphics LCD, run a server program on the Ethernet port, and detect push button
presses.
