bq27510 programming

I've found the answer in another thread.

Unfortunately there is the need for changing our customer hardware for connecting to ev2300.

Best regards,

Withold,

They can use the host processor to program the gauge via I2C using the Flashstream method.  Let me know if this is something that would be useful for them.

hi dMax,

thanks for your offer. I read about flashstream method, but at this time i have not enough information.

I'm very glad if you will help me.

Thanks in advance,

Withold

Hi Withold,

Have you already reviewed this document?

Please let me know what additional information you need.

Hi dMax,

no, I could not get/found slua541. Can you send it to me?

Thanks in advance,

Hi dMax....

I am struck up with a similar situation. I have bq20z90EVM and ev2300 for communication. But i found that i couldn't configure my fuel gauge with Version 0.9.59 bqEVSW. I guess there is a problem in my EV2300..... so, is it possible to configure my bq20z90 (to be fuel gauge for li-ion 3 cell) with i2c communication ????? I have experience in communicating with the inspired energy smart batteries with i2c..... PLEASE HELP ME OUT........

The BQ20ZXX devices only communicate via SMBus interface.  It's based on I2C format, but with more stringent timing.

then can you please guide me on how else to make my bq20z90 work???

hi,

I use a bq27510 on a stand alone application. It work correctly and now we start mass production. For this step, it's impossible tu use EV2300 and "bq evaluation software" to program the golden pack ; we need to program the fuel gauge with our embeded micocontroller.

I read the application note slua541 and I don't understand all. do you have a software example to program Golden pack from a microcontroller ?
