Software Setup and Operation
This section provides descriptions of the EVM software.
The supplied software is used to communicate with the TPS61050/2EVM. 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 box. 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. If a new update is available, the software notifies the user of the update, downloads and installs
the update.
The software then asks which version of the IC is on the board and the desired current limit. Check the
appropriate box for the IC, then select the current limit to be either 1000 mA or 1500 mA due to the 1500
mA rated inductor on this EVM, and finally click the continue button. Although the PCB can be powered up
after the software is initiated, in order for the user to be able to set the current limit to a value other than
the default, the PCB must be powered on before the software is initiated.
The software displays the main control panel for the user interface. Figure 1 shows the user interface main
control panel.
