bq34z100-G1 not auto-detecting with EV2300

Other Parts Discussed in Thread: BQ34Z100-G1, BQSTUDIO

Hi,

We are trying to connect to bq34z100-G1 fuel-gauge chip using I2C interface of EV2300. We've isolated the microcontroller from the fuel-gauge and have connected Clock, Data and Ground pins with the corresponding fuel gauge pins. Vout is not connected anywhere. The chip is connected with a 12V Lead-Acid battery.

When Connected to bqstudio 1.3.52, EV2300 is detected but the fuel-gauge is not auto detected.

Could anybody tell what we are doing wrong and why the fuel-gauge is not auto-detected?

Regards

Hi Kailash,

If you manually select the device from the list, does bqStudio work properly? We hear instances of this happening (it working ok after manually selecting), although it has been difficult for our SW team to replicate it on our own machines, in order to debug and fix it.

Thanks,

Terry

One further thought - what is the version of the ev2300 you are using? It will be shown in bqStudio after manually selecting a bqz, on the left side of the screen near the image of the USB plug.

Thanks,

Terry

Hi Terry,

Thanks for replying.

No, Manually selecting the chip was not working . The version of EV2300 being used is 3.1c.

But the good news is that the chip is detected now. Seems like earlier we were not properly isolating the chip from the microcontroller. It is working and we are able to calibrate it.

Thanks,

Kailash

Hi Kailash,

Ok, I'm glad to hear it is working ok now. For FYI, your ev2300 FW version is pretty dated, so if you run into more issues, you may update that. I'll need your email address to get that to you.

Thanks,

Terry

Hi Terry,

I am trying to connect to bq34z100-G1 fuel-gauge chip using I2C interface of EV2300. Could you help to provide the driver of bq34z100-G1 on EV2300?

Thanks.
