Lattice Semiconductor
The demo design integrates the following
• LatticeMico8 Microcontroller (RD1026)
• WISHBONE UART (RD1042)
• SPI WISHBONE Controller (RD1044)
• LatticeMico8 to WISHBONE Interface Adapter (RD1043)
Firmware running on the LatticeMico8 demonstrates control logic for the peripherals connected to a shared on-chip
WISHBONE bus and communication between the LatticeXP2 Brevia 2 Evaluation Board and a host PC connected
to the USB cable.

Set Up a VT100/ANSI Terminal Emulator
The Demo_LatticeXP2_Brevia_SoC preloaded in the LatticeXP2 Brevia 2 Evaluation Board is operated by interact-
ing with a monitor program. The monitor program sends and receives data across the RS232 communications port
on the LatticeXP2 Brevia 2 Evaluation Board. It is necessary to start and configure a VT100 or ANSI style terminal
emulator program like PuTTY, PuTTY Portable, Tera Term Pro (Windows) or Minicom (Linux).
Follow these steps to interact with the monitor program:
1. Connect the Brevia 2 Evaluation Board to your computer using the supplied USB cable.
2. Install the required device drivers
3. Start a terminal emulation program. The RS232 UART on the LatticeXP2 Brevia Evaluation Board is configured
a. Install the FTDI USB driver during the installation of Lattice Diamond or standalone ispVM programming
b. Configure a Virtual COM port driver as described in the FTDI installation guide available on the FTDI web-
to operate at 115.2bps, 8 data bits, 1 stop bit, no parity, and no flow control.
software. If you have already installed Diamond or ispVM without the driver, you can run the Diamond or
ispVM installation again and install only the driver.
