To read all the data from the bq27410 data flash, click on menu option | Data Flash | Read All |.
To write to a data flash location, click on the desired location, enter the data and press <Enter>, 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 bq27410 using the | Write All |
button.
The module calibration data is also held in the bq27410 data flash.
The bq27410 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.
