BQ76952: gg. file does not apply calibration gain parameters when import

Ali Batuhan Demirci

Part Number: BQ76952
Other Parts Discussed in Thread: BQSTUDIO,

Hi Ti Experts,

We have a custom board, and we try the import our calibrated data which has not modified data by the excel. When we click the import button, gain parameters (Cell-1 gain Cell-2 gain ... , CC gain, Capacity Gain etc.)  would not be imported to our new ic. (We can see  calibrated gain parameters in exported .gg file. However we could not see these parameters imported. ) We would like to use our calibrated data in our new IC's. 

Is there any method to import data in calibration tab in order to write  all data to new IC. We dont want to calibrate new IC each time.

    Hi Batuhan,

    The method has changed with evolution of BQStudio. 

    Calibrating each part likely gives the best performance, but if you have standard values you would like to load you can do that from the BQStudio Data Memory import.  

    In BQStudio go to the Window menu and select Preferences.  Select the Data Memory Import item.  By default it will look something like this:

    Delete the "Calibration" in the  "Class Names to be Preserved" box. 

    Apply and OK.  Now when you import you will load the calibration items from the gg.csv file also.  When you "write all" it will load the part.  Note there is an option for automatic write on the same preference page.

    If you are writing your own software you should be able to write to the calibration locations.  See the BQ76952 technical reference manual for addresses.
