    HI Jenny,

    The TRM of most of our gauges contains the section below:

    the ev2300 only facilitates communicating with our gauges via bqstudio or any other means you choose.  So data can be sents in bytes or blocks (see TRM)

    thanks

    Hi Onyx,

    Thank you for your reply, it's helpful for me.

    And the thing is that I purchased EV2300 debugger, I found that it could not implement I2C communication, and I test 4pin voltage is 0v. It demonstrated the port is broken?

    Looking forward your reply.

    Best Regards,

    Hi Jenny,
    pin 4 isn't supposed to read a voltage. IT isn't broken. The i2c port of the ev2300 does not have pull-ups. Most of our EVMs have pull-ups for the i2c lines. If your EVM does't have pull-ups you can install pull-upss to the 3.3v rail in your ev2300 .

    thanks
