which writes the entire tab of flash data, or select menu option | Data Flash | Write All |. The data flash
must be read before any writes are performed to avoid any incorrect data being written to the device.
The | File | Special Export | menu options allows the data flash to be exported, but it configures the
exported data flash to a learned state ready for mass production use.
The data-flash configuration can be saved to a file by selecting | File | Export | and entering a file name. A
data-flash file also can be retrieved in this way, imported, and written to the bq27620 using the | Write All
|button.
The module calibration data is also held in the bq27620 data flash.
The bq27620 allows for an automatic data-flash export function, similar to the DataRAM logging function.
This feature, when selected via | Options | Auto Export |, exports Data Flash to a sequential series of files
named as FilenameNNNNN.gg where N = a decimal number from 0 to 9.
The AutoExport interval is set under the | Options menu | with a minimum value of 15 s. The AutoExport
filename also is set under the | Options menu |.
When a check is next to | AutoExport |, the AutoExport is in progress. The same menu selection is used to
turn on/off AutoExport.
If the Data Flash screen is blank, then the bq27620 that is being used may not be supported by the
bqEVSW version that is being used. An upgrade may be required.
