3 Software Setup and Operation
This section provides descriptions of the EVM software and functionality.
The supplied software is used to communicate with the TPS650380EVM-054. Click on the icon on the
host PC to start the software. The host PC software first checks the firmware version of the USB-TO-GPIO
adapter. If an incorrect firmware version is installed, the software automatically searches on the Internet (if
connected) for updates. If a new update is available, the software notifies the user of the update,
downloads and installs the software. Note that after the firmware is updated, the user must disconnect and
then reconnect the USB cable between the adapter and PC, as instructed during the install process. The
host PC software also automatically searches on the Internet (if connected) for updates to the EVM
software. If a new update is available, the software notifies the user of the update, downloads and installs
the update.
V

and V

must be supplied for the software to detect the TPS650380 and run.
The software reads the registers on the TPS650380 and automatically determines which version of the IC
is installed. Even if the IC is disabled via the EN pin (JP1), the user can still communicate with the
TPS650380 if V

and V

are supplied.
The software displays the main panel for the user interface, shown in Figure 1 .
