AWR1843BOOST: concatenating multiple ADC .bin files.

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843

Hi,

I have a question about processing raw data captured from AWR1843 Boost +DCA1000 for an extended period of time so that the Raw data files become spilt into ***_Raw_0.bin, ***_Raw_1.bin, ***_Raw_2.bin. 

One file is a maximum of 1024MB which I can see mmwave studio limits the file size. When a single bin file is opened by matlab script provided, following error appears,

This is true as the numChirps = fileSize/numADCSamples/numRX  not returning an integer. 

My problem is how to read these files in the matlab script provided? I noticed mmwave studio somehow arrange all the files together and post-process all the frames.

Cound't find any documentation on how to do this.

Thanks a lot!

Isura!

    Hi,

    I think there is an FAQ that was created for this question.

    When the captured data is large and several .bin files are created it is not possible to use the post processing matlab scripts provided with mmWave Studio.

    The reason for this is that the captured .bin files will not include a complete number of frames. Start of one frame can be in one file and the end of the frame in the next.

    So, one will need to develop own matlab processing scripts for this case

    thank you
