EVM430-FR6047: USS_runAlgorithms with reference signal

Part Number: EVM430-FR6047

Good morning,

I am interested in the functions of the MSP430UltrasonicLibrary. I would like to know if it is possible to make a correlation between an acquisition signal and a reference signal. In the documentation, the function USS_runAlgorithms indicates the necessity to have both signals continuous in the LEA memory. I assume that it is not possible to start an acquisition only on one signal (only upstream or only downstream)?
If this is not possible, would it be possible to trick by copying the reference signal to one of the memory locations after the two acquisitions?

Yours sincerely,
Thomas

    Hi Thomas,

    The correlation function uses both the upstream and downstream signal to get the phase different between those two signals. You can copy one of your reference signal to the LEA memory and do the correlation. You can use the get UPS or DNS pointer function in the software to get the address.

    Best regards,

    Cash Hao
