BQ27510-G3 Programming/Calibration detailed procedure

Other Parts Discussed in Thread: BQSTUDIO, BQEVSW, BQ27510-G3

We upgraded our design from the BQ27510-G21 to the BQ27510-G3.  With the -G21, we had a programming and CAL process that used bqEASY for the start-to-finish process.  But with the -G3, this is not the case, and between using bqStudio and bqEVSW, there does not seem to be a step-by-step process to perform the CAL, Chemistry and Learning Cycle. 

These E2E posts seem to support a lack of such a process or document, but perhaps we have overlooked something, please advise.

    Hi 

    The process flow is as follows:

    identify your chem id using the online tool gpc chem.

    www.ti.com/.../gpcchem

    -Program the obtained chem id using the chemistry tab of bqstudio. Scroll till you find the chem id, select and then hit the update chemistry from data base button

    -Configure the data flash by using the parameter Q and A tab of bqstudio. Answer the questions and hit the save to gauge button . Alternatively, you can manually configure the data flash parameters one after the other by referencign the TRM but this is cumbersome.

    -Calibrate the gauge by following the calibration instructions in the EVM user guide.

    -carry out learning cycle accoding to the attached app note below

    8400.LearningCycleOverview_.pdf

    -once successful, extract a flashstream file or srec file using the golden image tab of bqstudio, This will be your golden file that you could program on multiple gauges.

    -after programming each board you can carry out calibration of each board. if that isnt feasible, then calibrate ten boards, take the average values of the calibration section of data flash, program these in a unit with the golden srec or flash stream file, then extract a new srec or flashstream file. This will be your new golden file. 

    Let me know if you have further questions.

    thanks
