USB Interface Board and I

C-Compatible Interface Program
Texas Instruments has created an I
2
C-compatible program and USB docking board (USB2ANY) that can
help exercise the part in a simple way. Contained in this document is a description of how to use the
USB2ANY interface box and interface software.
The LM3643EVM has the means to “plug into” the USB docking board. The USB docking board provides
all the control signals for the simple interface. Power to the part must be provided externally. A USB cable
(provided) must be connected to the board from a PC.
The I
2
C-compatible interface program provides all of the control that the LM3643 part requires. For proper
operation, the USB docking board should be plugged into the PC before the interface program is opened.
Once connected, and the program is executed, a basic interface window will open. The image below
shows the default settings.
