IWR6843ISK: Questions about savedata options in industrial toolbox 4.9 vital signs lab

Tool/software:

Hi.

I am using iwr6843isk and industrial toolbox 4.9 to customise the vital signs demo.

To check the data, I am saving the values to dataOutputFromEVM.bin using the save data option of the demo as shown in the picture, and then using main_readGUISavedBinary.m to check the unwrapped phase.

After saving several experiments, I realised that the data was not being overwritten with new data, but additional data was being written to the same data.

For example, the figure shows the output of outPhase for 2 experiments, and you can see that the values are all the same until about the 2.1*10^4th sample, and then the data is slightly different.
Why is this happening?

    Hi

    This version of the Vital signs demo is no longer supported. Can you please try the IWR6843ISK Vital signs demo from radar toolbox?

    You can use the below demo

    radar_toolbox_1_30_01_03\source\ti\examples\Medical\Vital_Signs_With_People_Tracking

    Do note that if you are using the latest version of radar toolbox, please use the visualizer from radar_toolbox_1_30_01_03, as heart rate is not displayed properly in the latest visualizer

    Regards

    Thank you for your response. I took a look at radar_toolbox 1 30  and was able to find the bin file and exe for the demo.
    But unlike industrial toolbox 4.9 , there is no source code and no explanation of the algorithm on how to estimate the vital signs.
    1) Is it possible to get the source code?
    2) Is the vital signs algorithm the same as industrial toolbox 4.9 ?

    Thanks

    Yes, the algorithm remains same. The source code is not provided with this demo
