bq27541 Calibration

Other Parts Discussed in Thread: BQ27350

Hello,

Does anyone know the save calibration to DF and calibration mode exit I2C commands? I received a procedure that states they are 0x72 and 0x73 with no data sent. That does not seen correct when using the EV2300 and the bq80xRW activex control because there is no function that allows no data to write to a I2C regester. Can I just use the EV2300 SMBus port in place of the I2C port?

Thanks!

    I answered my own question: See the SLUA415 for the bq27350, it has a complete procedure that has the correct command addresses and data for creating your own calibration programs. I have written a program to program with a Flashstream BQFS and DFFS and full calibration that uses the EV2300. The program can be executed by another test executive, i.e. LabVIEW, VEE, etc. and it will return measurements or results in a file based on command line arguments.
