Hello Team

I would like to know if it is possible to communicate bq78350 with Arduino Uno. Can you help with the library details and possible connection drawing.

    Hi Onyx/ Team

    I am trying to do serial communication between EVM and raspberry pi 3 . I need to the following information

    1. In case I connect the I2C connector which is 4 pin do I need to remove the shunts from J6 ,J7 and J14?
    2. Since by I2C communication we understand 2 pins SDA and SCL but from the board we get 4 pins. Can you tell me where should I connect those two.
    3.For I2C communication, we need the I2C adaptor address. In our case which one shall we specify.
    4. I would like to Read SOC, Voltage, Current and Temperature data. Is there reference projects or documents to carry out this communication.
    5. In case I run the BQ76940EVM at low voltage 30 VDC is there some changes which I should make (Min voltage 38VDC as per manual)

    Please suggest

    Regards
