Operation

Figure 11. Data Flash Screen, 1st Level Safety Class

To read all the data from the bq3055 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 click 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.

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 bq3055 using the Write All

button.

The configuration information of the bq3055 data is held in the data flash.

The bq3055 allows for an automatic data flash export function, similar to the SBS Data 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 seconds. The

AutoExport filename 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 bq3055 that is being used may not be supported by the

bqEVSW version that is being used. An upgrade may be required.
