IWR1443BOOST: About the acquired data of Vital Sign Lab

UNA

Part Number: IWR1443BOOST

Hi,

I have qestions about "mmWave Vital Signs Lab Uart Data Structure v0.1 0821.pdf". This document was taken from the following thread.
e2e.ti.com/.../619401

Q1: I got the data by running this Lab, but no value like Magic word was found in the acquired data. The magic word will be discarded when acquiring data? In other words, does the acquired data be stored from Frame Number(4 byte)?

Q2: Does Breathing rate and Heart rate on GUI use the value of "Breathing rate from peak counting" and "Heart rate from peak counting" in Data Structure?


Q3: If the acquired data starts from Frame Number, "Breathing rate from peak counting" and "Heart rate from peak counting" had the following values.
How is this value converted to Breathing rate and Heart rate on GUI?

Breathing rate from peak counting = 00 80 BB 41
Heart rate from peak counting = 00 90 8D 42

Best regards,
H.U

    Hi Akash,

    Thank you for your reply.

    I understand that Magic word is not included in the output packet in the current version Lab. Is my understanding correct?

    Could you tell me the specific calculation method of the breathing rate and heart rate ｗhich displayed on the GUI from each parameter of Vital Signs Output Stats?

    Best regards,
    H.U

    Hi H.U.

    This is correct Magic word is not included here.

    If you'd like to learn more about the theory behind this lab then I'd recommend looking at the Developer's Guide in the Automotive Driver Vital Signs Lab: dev.ti.com/.../

    I can understand that the Breathing Rate and Heart Rate using the output data defined in the following data structure, Can you disclose this calculation method with the document?

    Hello H.U,

    Apologies for the delay. The estimation algorithm is discussed on pages 8 - 10 of the Developer's Guide (dev.ti.com/.../ and the calculation is performed in the blocked called Spectral Estimation.

    Please make sure you have the latest version from the TI Resource Explorer as a new version just went live on Monday.


    Cheers,
    Akash
