Download Demo Designs
The Pico Power demo is preprogrammed into the Pico board, however over time it is likely your board will be modi-
fied. Lattice distributes source and programming files for demonstration designs compatible with the Pico board.
To download demo designs:
1.
Browse to the ispMACH 4000ZE Pico Development Kit web page (
www.latticesemi.com/4000ze-pico-kit
) of the
Lattice web site. Select the
Demo Applications download
and save the file.
2.
Extract the contents of
Pico_DK_DemoSource.zip
to an accessible location on your hard drive. Three demo
design directories (Demo_<device>_<demo>) are unpacked.

Recompile a POWR6AT6 Demo Project with PAC-Designer
Use the procedure described below to recompile any POWR6AT6 demo project for the Pico Evaluation Board. The
POWR6AT6 has limited I/O access so trim output features are limited. The only programmable option that can be
modified is the I
2
C address.
