5.2 Installing bqStudio
Find the latest software version in the tool folder http://www.ti.com/tool/bqstudio or search from
power.ti.com . Check periodically for software updates. Use the following steps to install the bqStudio
software:
1. Copy the archive file to a directory of your choice, extract all files and run the Battery Management
Studio-xxxxxx-Setup.exe application.
2. Follow the instructions and make selections as required on the setup windows selecting Next , as
required. TI recommends installing the software in the default location.
3. On the last window, select Finish to complete the bqStudio software installation.
5.3 Interface Adapter SMB
The interface adapter SMB connector must be connected to the SMB connector of the EVM for use with
the bqStudio software. Pull-ups for the SMBus are provided inside the adapter. The interface adapter
should not be connected to the I2C connector of the EVM.
5.4 bqStudio Operation
bqStudio is used to communicate to the bq78350 gauge for evaluation. It includes a number of tools to aid
in configuration of the bq78350 for evaluation. bqStudio will not communicate with the AFE and the I2C
connector of the EVM should not be connected while using bqStudio.
Although the software runs without connection to an interface board or powered device, it is
recommended to have both connected and the device on when starting the software. Follow the directions
in the
Gauge Quick Start section. Figure 2 shows connections for operation with the bqStudio software.
Start the software from the desktop shortcut Battery Management Studio or the menu Start → All
Programs

Battery Management Studio .
When started, the software looks for the communication interface and the device. If the device is found,
the registers will display such as in
Figure 11 . If the version is up to date the user may choose to proceed
to other evaluation steps. If the device is not found, it opens a Target Selection Wizard. This is expected
for a new EVM since the bq78350 is not programmed. Select the newest bq78350 version in the list and
click the
Finish button. This selection will be remembered until the software is re-stared. If the device is
not found, the user will be presented with a Proceed? window which must be acknowledged. If the
software still can not find the device, a Battery Management Studio popup window appears indicating
communication status. With a blank or un-powered part, this will indicate a timeout. Acknowledge the
message to proceed.
