Figure 10. Data Flash Screen

To read all the data from the bq27545 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 can also be retrieved in this way, imported, and written to the bq27545 using the | Write All |

button.

The module calibration data is also held in the bq27545 data flash.

The bq27545 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.
