CCS / TIDA-00449 : Flowchart of TIDA-00449

Part Number: TIDA-00449
Other Parts Discussed in Thread: BQ76940

Tool/software: Code Composer Studio

I am drawing the whole flow chart by referring to the flow chart on the DATASHEET.

Are there any additional resources I can refer to?

Also, is there an easy way to change 10S firmware to 14S firmware?

  • Hi ChiHyeon,

    If a flow chart is not involved in the TIDA-00449 documentation it is not available.  I do not know of additional resources.

    I am not familiar with the software.  If voltages are read as a block read 10 additional bytes of voltage data since the BQ76940 has voltage data in sequential bytes. For 14 cells cell 14 of the 15 cells is the one which should not be used, so skip that value in your collection.  If voltages are read individually be sure to read the 2 bytes for each cell in the same transaction, that technique should be in the code.  Once the new cell voltages are available, include them in the processing.
