Original question:

IWR1443: UART output data format and python reference

IWR1443: Decoding the output data from IWR1443BOOST EVM

Part Number: IWR1443

Hello,

we are interested in operating on the output data from the IWR1443Boost EVM through the USB of our computer.

In the related thread, there's been talk about a Python script dedicated to decrypting the data: is it available anywhere?

Or, in alternative, could you point me to somewhere in the available material where I can find the scripts related to this subject?


I have opened mmWave_demo_visualizer project in Code Composer Studio, but it seems a little confusing and too wide, to me (I am not well-versed into object-oriented programming).

We would like to plot the cloud of points coming from the radar inside our custom Matlab script, nothing more than that! Would you say it is doable with ease?

    Hello,

    Please refer to this previous thread: https://e2e.ti.com/support/sensors/f/1023/t/726567

    Hello and thanks for the suggestion, but what we need was probably misinterpreted.


    The .dat file requires demo visualizer active, while we would like, in fact, to just read and decrypt the UART (USB) data stream, as is.
    We have found some informations inside the C:\ti\lab0016_zone_occ_14xx\gui\mmw_demo_zone_occupancy.m file, but were hoping for a more straightforward code or approach.

    Thanks again,
    Michele

    Hello Michelle,

    The information regarding the UART data stream structure is in the mmWave SDK documentation. You can refer to this for a concise description of the data format.

    Alternatively, several examples are provided both in the source code of the online visualizer, Python script, and the Zone Occupancy Visualizer. Since the dat file is a capture of the UART stream the offline parsing has the same logic as the real time parsing in either of the visualizers. These are the reference code available to illustrate parsing of the data stream.
