BQ28Z610EVM-532: Default Baud Rate

Kathleen Gayo

Part Number: BQ28Z610EVM-532
Other Parts Discussed in Thread: EV2400

Hi,

I would like to ask what is the default baud rate of the BQ28Z610EVM-532. I have an MCU with Fast Mode I2C running in 400KHz. The MCU has 2 I2C Slaves, one is a custom I2C Slave and the other is the BQ28Z610EVM-532. The MCU was able to detect the custom I2C slave but it was not able to detect the BQ28Z610EVM-532.

I had checked the technical references and the datasheets but i cannot find the baud rate for the BQ28Z610EVM-532.

Thanks,

Hi Kathleen,

The default rate is 100kHz using the ev2400. We use fast mode for signaling.

HI Batt,

I changed the I2C speed and mode of the MCU we are using but it still failed to recognize the Fuel Gauge EVM. Please see attached image for the MCU I2C details.

The MCU which serves as the Master I2C was able to detect the other I2C slaves we have but it was not able to detect the Fuel Gauge EVM.

Kathleen,

You need to comm at addr 0xAA to query the gauge.
