Tool/software: Code Composer Studio

Hi,

I am trying to parse the file that is parseTLV.py available in Ti forum.. So, to parse the python file I am reading the input bin file by using teraterm (DATA PORT). But I am not getting the original input file, it is providing me the junk file in hex format.

    Manually also added the magic word in that above input binary file.. It haven't shown the offset index.. offset = 0

    Hello Priyanka,

    It is not clear what you're trying to do. If you are trying to parse the byte stream I recommend you consult the doxygen of the mmWave SDK for details of the data format structure. The python script may be out of date depending on which SDK version you are running the demo from. 

    Also whether your data appears as hex or bin or ASCII format in tera term is a setting in your terminal. Please consult the help info for tera term if needed.

    Hello Priyanka,

    Are you capturing the data using the Record function in the online visualizer? Please do so and check the .dat file. If you are running the correct demo there should be no issue such as you've described.

    Hello,

    The online visualizer does support IWR1642. Please use the drop down menu to select the device. It is the first one listed: https://dev.ti.com/gallery/view/mmwave/mmWave_Demo_Visualizer/ver/3.3.0/

    Hello Priyanka,

    There is no issue if you are using the correct firmware and device combination.

    I recommend that you use the example config profile_2d.cfg provided in the SDK at C:\ti\mmwave_sdk_03_03_00_02\packages\ti\demo\xwr16xx\mmw\profiles to first debug your data recording function.

    For further debug please provide more details:

    Hi,

    Now am using mmWave SDK - 2.0 because I can't able to use the latest SDK versions other than SDK 2.0, if I use 3.0 or 3.2 it throws the error in mss function, Console will be in empty and sometimes it Unable to open CLI.. So am using mmWave SDK version- 2.0

    Industrial toolbox version - 4.1.0

    Silicone version - ES2.0 (502AC)

    I m not using the online visualizer, my goal is to parse the people count rawdata.

    For this rawdata I tried to receive from teraterm or mobaxterm terminals. But I couldn't able to receive the exact rawdata needed, it is showing some junk data.. 

    Please check this and help me to resolve this issue..

    Are you able to run the people counting demo using the provided visualizer without issue?

    If you are running the people counting demo you should be loading the CFG used in the demo. Not the one you have posted.
