HSMC User-Defined LEDs
The HSMC port A and B have two LEDs located nearby. The LEDs are labeled TX and
RX. The LEDs display data flow to and from the connected HSMC cards. The LEDs
are driven by the Stratix V GX FPGA device. There are no board-specific functions for
the HSMC LEDs.
Table 2–32 lists the HSMC user-defined LED schematic signal names and their
corresponding Stratix V GX FPGA pin numbers.
Table 2–33 lists the HSMC user-defined LED component reference and the
manufacturing information.
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 you can easily remove
it to access components under the display. You can also use the header for debugging
or other purposes.
Table 2–34 summarizes the LCD pin assignments. The signal names and directions are
relative to the Stratix V GX FPGA.
