Part Number: BQ27542-G1
Other Parts Discussed in Thread: BQSTUDIO, EV2400

Hello,

i have a simple question.

Is there a way to configure manually a BQ27542 without using bqStudio and maybe using only Arduino IDE?

I want to use this fuel gauge for this battery:

Lithium/Polymer
3.7V
75mAh (is small)

From documentation is not clear to me what is the way how to do it. It seams that the fuel gauge must be calibrated automatically but i don't know how.

Can you help me?

Thanks,

Harald

No. BQ27542 is a flash gauge. The bqStudio is the only tool that can program the proper chemistry id to a bq27542 device and therefore you must use bqStudio and EV2400.

Hello. Do you know if Texas Instruments have any Fuel Gauge that can be programed without bqStudio and EV2400?

Thanks
