USING THE GUI
There are two basic modes to control/monitor the
FUSB307B. Pre-programmed firmware on the mcu can
control the FUSB307B and then the GUI can work with the
firmware to control/monitor the FUSB307B. The GUI can
also be used with the Register Map and Script tabs to
manually control/monitor the FUSB307B.
These two modes should not be used together, as it will
interfere with the autonomous mode state machine. By
default, the USB Type−C state machine is enabled. The
checkbox has to be de-selected to use the device manually.
Status information is shown in the top half of the window,
as well as in the “PD Control” tab and the “State Logs” tab.
Scripts can also be loaded in the “Script” tab for easier
loading of multiple sequential steps.
More information on specific operation of each section of
the GUI is provided in the following sections.

General
This tab provides the overall device status. The lower third
of this tab is the “Control” section. When the FUSB307B
EVB is initially connected to the PC, this section will
automatically update itself. At any time after that, the “Read
Config” button should be used before making any changes
to this section. The port type can be set to either DRP, Sink,
or Source, and other features can be enabled or disabled
here. After making any changes, press “Write Config” to
update the device with any changes.
