Dear Sir

I want to use microcontroller I2C communication with BQ27421.

I don't know how to write I2C code about initial and command transaction sequence.

Could you provide I2C sample code about BQ27421?

Thanks

Dear dMax

Thank you for providing information.

But I don't use os , only C language program to microchip.

Can I follow this link ( www.ti.com/.../slua467b.pdf ) about command transaction sequence?

Before using BQ27421, should be send initial command?

Thanks
