IWR1443BOOST: dat file Open in MATLAB

Part Number: IWR1443BOOST

Hi Guys!

I'm Wonjin Eom.

I asked a question about reading dat file captured in mmWave visualizer and a kind man replied that matlab is usable to open dat file.

Therefore, I opened the dat file in matlab but the data was broken like below.

It is same in notepad or wordpad so I cannot recognize how to read my dat file.

I referred some doxygens in sdk, I cannot understand how can I get raw object data in PC.

Somebody help me please. :(

    Hello,

    Within the SDK there is an m-file, capture_demo.m, that provides an example of offline analysis with the dat file. 

    The file can be found in the directory mmwave_sdk_<ver>\packages\ti\demo\xwr14xx\capture\ gui\capture_demo.m 

    If you are going to run the capture_demo.m file please make sure the parameter values such as samples, # of chirps, etc are in alignment with the values you used from the capture script. Also, for the m-file to work make sure your .dat file is located or added to your MATLAB path.

    If you have not tried running this m-file yet please try it and let me know if this helps.

    Best,

    Amanda
