BQ30Z554-R1: Help on bq Evaluation Software 0.9.92 - Pro Interface

Part Number: BQ30Z554-R1

Hi, 

I'm having difficulties in understanding how the Pro interface for bq Evaluation Software 0.9.92 works.

The test condition require an input to ManufacturerAccess() 0x0022 – FET Control and to read back the output from SMB Register ManufacturingStatus() which is expected to be 0x0168 (Bit 4 - FET Flag

Cleared) and also from SMB Register OperationStatus() which is expected to be 0x00106101 (Bit 2 - CHG Flag Cleared; Bit 1 - DSG Flag Cleared).

May I know how the input will be written in the bq Evaluation Software 0.9.92 and how i can read back the result from SMB Register ManufacturingStatus() & SMB Register OperationStatus().

Thanks

  • Bryon,

    To send the enable FET command you have it correct on the screen shot. it is a write word to address 0x00 command 0x0022. To read Operation status you would want to perform a block write to address 00 with data 0x5400 (little endian) then do a read back on 0x00 again. 

    Thanks,
