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 Evaluation Board and a host PC connected to
the RS232 cable.

Set Up a VT100/ANSI Terminal Emulator
The Demo_LatticeXP2_Brevia_SoC preloaded in the LatticeXP2 Brevia 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 Evaluation Board. It is necessary to start and configure a VT100 or ANSI style terminal
emulator program like HyperTerminal (Windows) or Minicom (Linux).
The RS232 port on the LatticeXP2 Brevia Evaluation Board is configured to operate at 115.2Kbps, 8 data bits, 1
stop bit, and no parity, and no flow control. Once the terminal emulator is running on the host computer, and the
RS232 cable is attached between the host computer and the LatticeXP2 Brevia Evaluation Board you will see the
following banner displayed when the board is powered, or following a RESET button assertion.
