Character LCD
The development 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 229 summarizes the LCD pin assignments. The signal names and directions are
relative to the Stratix V GX device.
