RS-232 Interface
A 2x5 header (J38) provides a RS-232 port connection to the LatticeECP3 device via a RS-232 transceiver
MAX232. Either the DB25 or DB9 cable can be connected to this header for providing a RS-232 pot with industrial
standard pinout. Table 28 shows the pin connections of this header.
Table 28. RS-232 Interface Header Pin Connections (J38)
LCD Interface
A 2x9 header (J43) provides a connection to LCD modules such as the 20-character x 2 line LCD module LCM-
S02002DSR or LCM-S02002DSR (with backlight LED) from Lumex. The board includes two variable resistors for
LCD adjustments. VR6 adjusts the backlight and VR5 provides contrast adjustment. A user design must be
included in the FPGA to drive this feature. This header can also be used for probe points for observing FPGA pins.
Pin 1 and Pin 2 of header J43 are dummy pins that connect to nothing. When installing the Lumex LCD module,
these two pins should be skipped. Table 29 shows the pin connections of this header.
