February 2011 Altera Corporation Arria II GX FPGA Development Board Reference Manual

Table 2–30 lists the HSMC user-defined LED component reference and the

manufacturing information.

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 2–31 summarizes the LCD pin assignments. The signal names and directions are

relative to the Arria II GX FPGA.

Table 2–32 shows the LCD pin definitions, and is an excerpt from the Lumex data

sheet.
