Dears，

      The project time emergency，we need bq27220 modeling file to run through the code，

      Would you help to support Existing modeling file ，

      And could you help to write a file built process, how to judge the data has been written in；

    hi Cris,
    I do not understand what your request is. The bq27220 is a CEDV ROM based gauge that needs to be properly configured in order to function properly. You need to use our gpccedv tool to obtain the coefficients that need to be programmed on your gauge. The tool has instructions on what to do. Also, your host needs to have non-volatile memory to store your configuration settings should power get cut off.

    thanks
    Onyx

    Hi Onyx，
    Sorry for unclear stated，
    Do you have the final file what have configured ？gm.fs file？we want run the system first；
    So we can refer to your existing file format to operate，Even if the configuration parameters are different。
    many thanks；

    Hi Cris,
    The gauge comes with default settings. For a particular battery, you need to run the tests outline in the gpccedv tool and extract and program the coefficients for the device to work. I do not have any files to share
    thanks
