C Digital Interface Guide
The Picor Buck GUI operates under the Windows TM 7
or XP (Service Pack 3) environment. JAVA
TM
version
1.5 or greater 32 bit version is required. This
software has been tested using Windows 7 32 bit
and 64 bit and Windows XP with Service Pack 3.
USB Interface Hardware
The Picor Buck GUI software is designed to work
with the LinkM
TM
USB to I
2
C interface device
manufactured by ThingM. Information about the
LinkM can be found at http://linkm.thingm.com/. A
Windows based PC is required with a dedicated USB
port. The use of USB expansion ports; especially
those that are heavily loaded, is not recommended.
The LinkM interface can be mounted directly to the
PI33XX-2X Evaluation Board using a straight 4 pin
header (see Figure 1). Users who wish to connect the
LinkM in this manner will need to use a male to
female USB extension cable. This method works very
well and is the preferred method. Other users may
wish to probe the I
2
C bus or connect to it with ball
clips. For this option, the LinkM datasheet describes
the recommended connectors to build such a cable.
