Operation

This section details the operation of the bq28400 EVSW software.
8.1 Starting the Program
Run the bq Gas Gauge Evaluation Software from the Start | Programs | Texas Instruments | bq28400
EVSW menu sequence. The SBS Data screen
clicks the Refresh (single time scan), or when the Keep Scanning checkbox 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 65535 ms. Only items that are selected for scanning are scanned
within this period.
The bq Gas Gauge Evaluation Software provides a logging function that 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 must be manually unchecked.
The logging intervals are specified under the | Options | menu with the maximum value of 65535 ms. The
log interval cannot be smaller than scan interval because this results in the same value being logged at
least twice.
