Reference Manual
Table 2–15 lists the general LED schematic signal names and their corresponding
Cyclone V E FPGA pin numbers.
HSMC LEDs
Board references D20 and D21 are LEDs for the HSMC port. 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 daughtercards. The LEDs are
driven by the Cyclone V E FPGA device.
Table 2–16 lists the HSMC LED schematic signal names and their corresponding
Cyclone V E FPGA pin numbers.
Character LCD
The development board includes a single 14-pin 0.1" pitch dual-row header that
interfaces to a 2 line × 16 character Lumex character LCD. The character 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 2–17 summarizes the character LCD pin assignments. The signal names and
directions are relative to the Cyclone V E FPGA device.
