8 Operation

This section details the operation of the bq27545 EVSW software.

8.1 Starting the Program

Run bq27545 EVSW from the Start | Programs | Texas Instruments | bq Evaluation Software menu

sequence. The DataRAM screen (Figure 9) appears. Data begins to appear once the <Refresh> (single

time scan) button is clicked, or when the <Keep Scanning> check box is checked. To disable the scan

feature, deselect <Keep Scanning>.

The continuous scanning period can be set via the | Options | and | Set Scan Interval | menu selections.

The range for this interval is 0 ms to 65,535 ms. Only items that are selected for scanning are scanned

within this period.

The bq27545 EVSW provides a logging function which logs the values that were last scanned by the

EVSW. To enable this function, select the Start Logging button, which causes the Keep Scanning button

to be selected. When logging is Stopped, the keep scanning button is still selected and has to be manually

unchecked.

The logging intervals are specified under the | Options | menu with the maximum value of 65,535 ms. The

Log interval cannot be smaller than scan interval because this results in the same value being logged at

least twice.
