Other Parts Discussed in Thread: UNIFLASH, AWR1642

Hi,

I want to test the vital signs lab on the AWR BOOST but the prebuilt binaries with uniflash (xwr14xx_vitalSigns_lab_mss.bin and xwr12xx_xwr14xx_radarss.bin) to flush the device, it doesn't work.

Is the vital signs lab is supported by the AWR 1642 BOOST !!

thanks,

Med

I did it, but using directly the demo, without compiling any code on the CCS.

Hi,

First, you should be flashing only the meta (combined images) file, not the individual MSS and RadarSS .bin files.

The output file is selected with this line of code:

QFile outFile("dataOutputFromEVM.bin"); // File to save the Data

So, it does not specify a directory, which normally results in the file being saved in the same directory where the gui is or was started from.

Dave,

do you propose any method to extract heart rate and breathing rate from this .bin file ?

thanks,
Ahmed

Hi Ahmed,

This demo is currently being updated, and documentation is being added to explain the output format. This will be provided in the next release, hopefully in a few weeks. In the meantime, the only thing I can suggest is to examine the Matlab code to see the ordering of the writes to the file. Once you know that, you can write either another Matlab or Visual Studio (i.e. C) program to analyze the data.

there is any other method to log directly real HR and BR values ?

Yes. You can modify the Matlab source to create your own log file in whatever format you desire.

which Matlab source code are you talking about ? is there alredy one ?

Sorry, wrong vital signs demo. This demo uses C++ for the gui; the source is in vitalSigns_host\gui\gui_source. Look for the function processData in mainwindow.cpp. The data is written with these lines:

dataSave = data;
outFile.write(dataSave.fromHex(data), demoParams.totalPayloadSize_bytes /*TOTAL_PAYLOAD_SIZE_BYTES*/);

You will need to backtrack the variable data to see how it is filled, or change it to write what you would like.

Hi dave,

thanks again. Is there maybe a way to extract the Frame Indexes to a .idx file and a .dat file containing the frames as a result of the driver vital signs lab demo gui app ??

could they be stored somewhere in the lab directories ? rather than the dataOutputFromEVM.bin ??

(the vital signs measurement demo GUI when running, it is showing the frame indexes, HR, BR... so maybe they are stored somewhere apart !!? )

thank you in advance,

Ahmed

Actually, I want to have the frame indexes file and the dat file from thr dataOutputFromEVM.bin (if it is the only possible output after executing the lab).

Our demos are meant to be a starting point. You will need to modify and rebuild the demo to suit your requirements.
