4.4 Software Operation
This section describes connection of the communication interface to the EVM and operation of the
software.
Although the software runs without connection to a powered device, TI recommends having the device on
when starting the software. Follow the directions in the quick start section. Figure 1 shows connections for
operation with the GUI software.
Start the software from the desktop shortcut bq769X0 Evaluation Software or the menu Start → All
Programs → Texas Instruments → bq769X0 Eval Software
When started, the software looks for the communication interface and the device. If either is not found, a
popup window appears and must be acknowledged. When communication is established with the device,
the main window appears as shown in Figure 3.
The bq76940/bq76930/bq76920 software uses popup help tips on many of the control features.
