    Hi Mihir,

    Are you needing help with Hardware, Software, or both for interfacing with the board?

    Please reference the BQ32002 datasheet for details on HW setup/considerations and the required data format the device expects when being written to or read from.

    For software help I'd suggest referencing the i2c_eeprom example within C2000ware, located at the directory below:

    C:\ti\c2000\C2000Ware_2_00_00_02\device_support\f2806x\examples\c28\i2c_eeprom

    This is an interrupt driven i2c example for interfacing with an eeprom slave. You will need to edit the software to fit your slave device and application. For a more straight-forward SW example to work off of you can look at what I provided in the below E2E post. Simple functions for reading/writing to i2c slave registers are included:

    Best,
