EVM430-FR6043: VFR Flow + Temperature Calibration & FR6043_USSSWLib_template_example code

Part Number: EVM430-FR6043

Hello,

I am using EVM430-FR6043 and Ultrasonic Sensing Design Center GUI to design a gas flow meter. When I select EVM430-FR6043 Gas as the meter option, VFR Flow + Temperature Calibration is disabled (Every part in the VFR Flow + Temperature Calibration tab is greyed out). Is there a way to use this feature for the EVM430-FR6043 Gas meter? Why is this calibration mode blocked in this mode? Is there a specific reason why this section is disabled for the EVM430-FR6043 gas meter?

I was looking through the TI USS library and the template code and found a few functions such as USS_calculateVolumeFlowRate, USS_initialSearchQuad, and USS_calibrateVFRFlowTemperature which I am assuming are used in VFR Flow + Temperature Calibration feature. I would like to know if the FR6043_USSSWLib_template_example code is the same as the one already loaded on EVM430-FR6043 and whether I could gain access to the VFR Flow + Temperature Calibration feature if I design my code utilizing these functions. Since EVM430-FR6043 successfully connected to the Ultrasonic Sensing Design Center and is functioning, I assumed that the board came with the default code loaded onto it. Is this the same code/program as FR6043_USSSWLib_template_example? Will the board and the GUI work the same as now even when I load FR6043_USSSWLib_template_example code again to EVM430-FR6043 using CCS?

Thanks in advance.

    We do not provide the calibration for gas meter that is why it is greyed out.

    Hello Gary,

    Thank you for your response.

    So the calibrations provided by the GUI are only for the water/liquid flow meter? 

    How about USS_calculateVolumeFlowRate, USS_initialSearchQuad, and USS_calibrateVFRFlowTemperature functions that are present in FR6043_USSSWLib_template_example code? Are they also only to be used for the water/liquid flow meter? 

    Also, is the FR6043_USSSWLib_template_example code the same as the application that came with EVM430-FR6043? In other words, if I build and load the FR6043_USSSWLib_template_example code and load it onto the EVM430-FR6043 board, will the board function with the GUI and output similar values as it is now?

    Thank you,
