EVM Hardware and Software Setup
This section describes how to install the bq27425EVM PC software and how to connect the different
components of the EVM.
5.1
System Requirements
The bq27425EVSW software requires Windows 2000 or Windows XP. Drivers for Windows 98SE are
provided, but Microsoft™ no longer supports Windows 98; therefore, Windows 98 can have issues with
USB driver support. The EV2300 USB drivers have been tested for Windows 98SE, but no assurance is
made for problem-free operation with specific system configurations.
5.2
Software Installation
Find the latest software version in the bq27425 tool folder on power.ti.com. Make a search by Part
Number for bq27425 to access the tool folder. Use the following steps to install the bq27425EVSW
software:
1. Ensure that the EV2300 or EV2400 is not connected to the personal computer (PC) through the USB
cable before starting this procedure.
2. Open the archive containing the installation package, and copy its contents into a temporary directory.
3. Open the software file that was downloaded from the TI Web site.
4. Follow the instructions on screen until completing the software installation.
5. Before starting the evaluation software, connect the EV2300 or EV2400 to the computer using the USB
cable.
6. If EV2300 is connected, wait until system prompt “new hardware found” appears. Choose “select
location manually”, and use the “browse” button to point to subdirectory TIUSBWin2K-XP-1.
7. Answer “continue” to the warning that drivers are not certified with Microsoft™.
8. If EV2300 is connected, after previous installation finishes, another system prompt "new hardware
found" appears. Repeat steps 1 through 5, but specify the directory as TIUSBWin2K-XP-2.
9. Answer "continue" to the warning that drivers are not certified with Microsoft. Driver installation is now
finished.
10. For EV2400, the driver should be installed along with software installation.
6
Troubleshooting Unexpected Dialog Boxes
The user that is downloading the files must be logged in as the administrator. The driver is not signed, so
the administrator must allow installation of unsigned drivers in the operating system policy.
7
Hardware Connection
The bq27425 evaluation system comprises three hardware components: the bq27425 circuit module, the
EV2300 or EV2400 PC interface board, and the PC.

Operation
This section details the operation of the bq27425 EVSW software.
8.1
Starting the Program
Run bq27425 EVSW from the Start | Programs | Texas Instruments | bq Evaluation Software menu
sequence. The DataRAM screen (Figure 7) appears. Data begins to appear once the (single
time scan) button is clicked, or when the check box is checked. To disable the scan
feature, deselect .
The continuous scanning period can be set with the | Options | and | Set Scan Interval | menu selections.
The range for this interval is 0 ms to 65,535 ms. Only items that are selected for scanning are scanned
within this period.
The bq27425 EVSW provides a logging function which logs the values that were last scanned by EVSW.
To enable this function, select the Start Logging button; this causes the Keep Scanning button to be
selected. When logging is stopped, the Keep Scanning button is still selected and has to be manually
unchecked.
The logging intervals are specified under the | Options | menu with the maximum value of 65,535 ms. The
Log interval cannot be smaller than the scan interval because this results in the same value being logged
at least twice.
