2. Could you please provide some drive codes for BQ27750 and BQ27742?

3. whether Battery gauge will happen to electric quantity jump if the battery gauge stays in high temperature or low temperature?

    Hi, Wenting

        For HDQ communication, it is enabled by sending command from I2C instead of GPIO pin configuration.

        For the driver, I think Onyx or Dominik may help on this.

        For electric quantity jump, typically called as SOC jump or Remaining Capacity Jump, could be minimized by optimizing the battery model data stored in the data flash, Onyx can help you for details
