Operation
This section details the operation of the bq27410 EVSW software.
8.1 Starting the Program
Run bq27410 EVSW from the Start | Programs | Texas Instruments | bq Evaluation Software menu
sequence. The DataRAM screen (see Figure 7) appears. Data begins to appear once the <Refresh>
(single time scan) button is clicked, or when the <Keep Scanning> check box is checked. To disable the
scan feature, deselect <Keep Scanning>.
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 bq27410 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.

bqEASY™ Software
11.1 Introduction
Texas Instruments fuel gauges, employing the Impedance Track™ algorithm, offer an unmatched array of
features and benefits. Sometimes, however, the wide range of configuration settings can seem
challenging to get started with the evaluation process. In addition, determining the correct chemistry model
and producing the 'golden image' file can be time consuming. The bqEASY™ program is designed to
greatly simplify the process of configuring, calibrating, selecting chemistry, and performing learning cycles
through the step-by-step use of a wizard program.
The bqEASY™ software runs inside the current EV software when it is executed by clicking the bqEASY
button in the left column of buttons below the Calibrate button in the EV software

11.2 Program Navigation and Flowchart
The sequence of operation of the bqEASY™ program can be understood by reviewing the basic flowchart
in Figure 12. Using the program is simple – just start a new project and follow the steps sequentially from
1A to 5C. You can use the Next button, or click on the top tabs and left subsection labels to move to any
desired page. Some operations must be completed in sequence due to data dependencies, or to
implement the proper flow. Therefore, it is recommended that the prescribed sequence be followed, at
least at first.

bqEASY™ Software
Figure 12. bqEASY™ Flow Chart
11.3 Simplified Configuration Procedures
These simplified configuration procedures can be used to quickly set up the parameters without navigating
through the entire user interface.
1. Simple configuration of the gas gauge with default or custom data:
(a) Open the current EV software, and click the bqEASY button in the left column of buttons below the
Calibrate button in the EV software.
(b) Click the "2. Configure" tab at the top row of bqEASY™ tabs. (Note: You can skip the first tab.)
(c) Answer all questions, or leave defaults for all of tab "2", but be sure to click the OK button at the
bottom of each tab "2" page to ensure that a Completion Checkmark appears for each page.
(d) On page 2H, when you click the OK button, the software asks you to write to the data-flash
memory. Click Yes for OK to write to the data flash.
Your Gas Gauge Module now has the data flash configured as you declared with all the information
entered in tab "2. Configure".
11.4 Files
The bqEASY™ software uses four types of files to configure a fuel gauge.
1. ENCR – These are default data-flash definition files found in the \bq_Evaluation_Software folder. The
.ENCR file is basically a copy of the entire data flash from a fresh gas gauge prior to any data-flash
updates either by the user or the gas gauge. They are unique for each version of each TI fuel gauge
product. If you are working with a new version fuel gauge and an older version of bqEASY™ software,
the correct file may not be present. This requires a new version of the EV software with bqEASY™
software. Navigate to the TI Web site in the EVM tool folder for the device being used, and download
the latest version, or contact TI. For the bqEASY™ program, the .ENCR files act mainly as a dictionary
to look up the address for a given data-flash location. For bqEVSW, they define screen parameters
including address, display formulas, and data type. An error message appears if the correct .ENCR file

cannot be found.
2. DFI (Data-Flash Image Files) – These are binary images of the fuel gauge data flash with modified
values based on the application. Because of the binary format, it is quick and easy to transfer them to
and from a gauge. Each fuel gauge model and firmware version has a unique read-only .DFI which is
found in the ..\bq_Evaluation_Software\Plugins\Device_Defaults folder of the application. During the
bqEASY™ process, intermediate versions of .DFI files are recorded with current updated data in order
to prevent the possibility of corruption. Then, the final output of the bqEASY™ software is also a .DFI
file which is the 'golden image' that is programmed into each production unit. This output file is placed
in the ..\bq_Evaluation _Software\Plugins\Projects folder.
3. EZY (bqEASY™ Project Files) – These are read-write text files which record header information
regarding a project, answers to the wizard questions, and status regarding the stage of completion (the
red check marks). They are kept in the ..\bq_Evaluation _Software\Plugins\Projects folder.
11.5 Completion Checkmark
As the wizard questions and tasks are completed, completion checkmarks appear in two places – along
the task list on the left and on the category tabs on top. A checkmark on a top tab only appears after all
tasks in the category have been completed. Completion marks are saved in the .EZY project text file.
When a completed or partially completed project file is opened, the user is given the chance to erase the
checkmarks.
11.6 Device Detection
The bqEASY™ program is designed to work with a fuel gauge present and already communicating with
the bqEVSW evaluation software through the EV2300 or EV2400 USB interface. When the evaluation
software is started, it reads the device type and displays it on the upper title block. This information is
used by the bqEASY™ program to select the correct default data-flash image (.DFI) and data-flash
configuration file (.ENCR) for this particular device. To ensure that the device has not changed, the
bqEASY™ software also checks the device type when the bqEASY button is pressed. If the correct files
are not found, first check the TI Web site in the EVM tool folder for the part being used, and download the
latest version of EV software with bqEASY™ support. If that fails to help, contact TI.
1. Setup
As the wizard questions and tasks are completed, completion checkmarks appear in two places –
along the task list on the left and on the category tabs on top. A checkmark on a top tab only appears
after all tasks in the category have been completed. Completion marks are saved in the .EZY project
text file. When a completed or partially completed project file is opened, the user is given the chance to
erase the checkmarks.
2. Configure
A series of eight screens is used to collect information about the battery pack application to enable
automatic configuration of the most critical data-flash parameters.
3. Calibrate
If you wish to proceed with either automatic chemistry selection or golden unit learning cycles, the
Impedance Track™ fuel gauge must be accurately calibrated. The bqEASY™ screens simply ask the
user to use the calibration screen of the bqEVSW for this purpose.

FCC Warning
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION
PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and
can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15
of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this
equipment in other environments may cause interference with radio communications, in which case the user at his own expense
will be required to take whatever measures may be required to correct this interference.
EVM Warnings and Restrictions
It is important to operate this EVM within the input voltage range of 0 V to 5 V and the output voltage range of 0 V to 5 V .
Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are
questions concerning the input range, please contact a TI field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the
EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load
specification, please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than 60° C. The EVM is designed to
operate properly with certain components above 60° C as long as the input and output ranges are maintained. These components
include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of
devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near
these devices during operation, please be aware that these devices may be very warm to the touch.
