MSP430FR6047: MSP430FR6047EVM_USS_Water_Demo GUI Doesn't Match Results

Tool/software:

Hello All,

I am using the MSP430FR6047EVM_USS_Water_Demo project to view the waveform and I am extracting both the USS_Algorithms_Results_fixed_point and the USS_Algorithms_Results and printing out the iq44DeltaTOF and deltaTOF through a serial port.  I am bit confused as both results are not matching what the GUI shows.  Is the GUI scaling the value some how?

    Hi Eric,

    Are you doing any conversion on the IQMath values after sending them through the serial port, or just using the raw values? You may want to review the IQMath user's guide to check the functions to convert the IQMath values. The conversion from IQMath format is the only translation / scaling I would expect here.

    Thanks Dylan, The user guide helped. I also found that the value was in seconds instead of pico seconds so I was off by a factor of 10E-12 when I got it working. Thanks!
