MSP430FR6047: EVM430-FR6047 using calibration files

Hi Ido,

Have you changed the value of the volumeCalibrationOption variable in your project before running the algorithms?

I ask this because I have found the following comments in the USS code:

//! \brief The following API scales Volume Flow Rate by the additional scale 
//! factor.
//!
//! \n \n \b Note1: USS_getResultsInFloat must be called prior to calling
//! this function.
//!
//! The API multiplies results->volumeFlowRate by meterConfig->volumeAddlScaleFactor.
//! The API is only needed when the additional scale factor is larger than 1.0f. 
//! It checks the volumeCalibrationOption member in the
//! USS_Algorithms_User_Configuration structure.
//! For example:
//! If volumeCalibrationOption != USS_Alg_volume_flow_Calibration_Option_disabled
//! Then it also scales results->volumeFlowRateNoCalib member by volumeAddlScaleFactor.
//! If volumeCalibrationOption == USS_Alg_volume_flow_Calibration_Option_disabled
//! Then results->volumeFlowRateNoCalib = results->volumeFlowRate.
//! If API return message code USS_message_code_valid_results, then algorithms
//! result are valid.
//!
//! \param[in] config  is a pointer to the USS SW Library user configuration
//! \param[in] results  is a pointer to the USS Algorithms Result structure
//!
//! \return USS_message_code
extern USS_message_code USS_scaleVolumeFlowRate(
        USS_SW_Library_configuration *config,
        USS_Algorithms_Results *results);

It looks like if you do not disable the calibration using that variable, then the volumeFlowRateNoCalib will be assigned the same value as volumeFlowRate. In other words, it looks like the volumeFlowRateNoCalib will actually be scaled according to your calibration. So my guess is that it is using your calibration file, the problem is just that the variable name is a bit misleading. You could try changing that variable to disable  calibration and then re-checking the flow rate it calculates to verify this.
