4.4.1 Detection Data Input Mode

In this mode, users need the MSPM0 Gauge board and a real battery for test. The detection data (Vcell, Icell, Tcell) comes from the real detected signals. The GUI can help to record the battery running data for further analysis.

For software setting, users need to download the gauge code to the LaunchPad after changing the detection mode to DETECTION_DATA_INPUT in Gauge_UserConfig.h.

Detection Data Input ModeFigure 4-11 Detection Data Input Mode

For GUI control, users need to select the right port with the name XDS110 Class Application or User UART and click the connect button. If the MCU already works, then users see the test data at MCU Test Data block. After users click the disconnect button, the data is saved in the CSV type under the same address of GUI with the name YYYY-MM-DD-HH-MM-McuData.csv.

Note: If there is some high frequency noise on the Vcell, Tcell and Icell, then TI recommends users to add an additional IIR filter for these algorithm inputs.
