HSMC User-Defined LEDs
Each HSMC port has two LEDs located nearby. There are no board-specific functions
for the HSMC LEDs. The LEDs are labeled TX and RX, and are intended to display
data flow to and from the connected HSMC daughtercards. The LEDs are driven by
the Arria V GT FPGA.
Table 2–17 lists the HSMC user-defined LED schematic signal names and their
corresponding Arria V GT FPGA pin numbers.
LCD
The development board includes 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 2–18 summarizes the LCD pin assignments. The signal names and directions are
relative to the Arria V GT FPGA.
