Power 7-Segment Display
The power measured by the MAX II CPLD and associated A/D is displayed on board
reference U27, which is a dedicated 7-segment display connected to the MAX II
CPLD, labeled Power Display.
Table 2–31 lists the power 7-segment display component reference and manufacturing
information.
LCD Displays
The development board accommodates two LCD displays:
■ Character LCD
■ Graphics LCD
The character display is a 16-character, by 2-line LCD display. The graphics is a
128 × 64 pixel transmissive graphics LCD. The two displays have separate buses. This
section describes both displays.
Character LCD
The board contains a single 14-pin 0.1 in. pitch dual-row header, used to interface to a
16-character by 2-line LCD display, manufactured by Lumex (part number
LCM-S01602DSR/C). 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—or to use the header for debugging or other purposes.
Table 2–32 summarizes the character LCD interface pins. Signal name and direction
are relative to the Stratix III FPGA. For functional descriptions, see Table 2–33 .
