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
