    Hi, 

    There is no CRC function add to demo code yet.

    But there is CRC check API in the demo code already.

    Fullscreen
    1
    2
    Checksum(unsigned char *ptr, unsigned char len)
    CRC8(unsigned char *ptr, unsigned char len)
    XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

    Can you try add this function by your self.

    Another steps you need to do is enable BQ's CRC via I2C.

    Please refer to BQ's datasheet: https://www.ti.com/lit/ds/symlink/bq76952.pdf

    This function will be add to SDK in next few month.

    If you encounter any problems adding CRC feature, please contact me.

    Regards,

    Helic
