The starter board contains a single 14-pin 0.1" pitch dual-row header that interfaces to
a 16 character × 2 line Lumex LCD display. The LCD has a 14-pin receptacle that
mounts directly to the board's 14-pin header, so it can be easily removed for access to
components under the display. You can also use the header for debugging or other
purposes.
Table 2–21 summarizes the LCD pin assignments. The signal names and directions are
relative to the Cyclone IV GX Transceiver.
