IWR6843ISK: IWR6843ISK

Part Number: IWR6843ISK
Other Parts Discussed in Thread: IWR6843, MMWAVE-SDK

I want to use IWR6843ISK interfacing with my own embedded platform. So here are my questions:

1. Is it possible to use some code on my platform in place of TI visualizer to set the parameters and get the RX data. Is there any reference available for this.

2. The RX data what we get is basically the detection. Is that correct? If it is detection then is there any structure available which I can probe the IWR6843 and fetch it to get the meaning out of the detection.

Thanks

    Hi Anjan,

    Would you please elaborate on what you are trying to do?

    Would you also elaborate what you mean when you say you are interfacing IWR6843ISK board with your own embedded platform?

    Your first question references the post-processed object data that is sent to the PC over UART, whereas your second question references Rx Analog data that input to the radar front end. Both are on completely different ends of the block diagram (below).

    Regards,

    Hi Akash,
    Sorry for short description. Here is the details of what I am trying to do.

    I want to connect the IWR6843 to the external APU which is running linux. It has 2 USB ports so I can use both the USB for sending the configuration and reception of data. I don't want to use the TI visualizer to configure and reception of data. I want to develop my own cli which can run on linux and an application which can receive the RX data so that I can use the results in my algorithm. Ex(detecting the static and dynamic objects and take some necessary action)

    Now my questions are:

    1. Do you have any reference cli code which I can refer to build my own standalone cli which can run on linux and can send commands to the IWR6843.

    2. what are the total available configuration commands for IWR6843?

    3. Is the RX data received from UART is in TLV format? If it is in TLV format then please help me with some document which specifies the format. 

    I want to parse the data and use the information in my algorithm. 

    Basically what TI is doing with TI visual analyzer I want to do it using some app(written in C) running on external APU which is running Linux.

    Thanks

    Anjan

    Hi Anjan,

    1. I would recommend looking at the Gesture Recognition Lab in the Labs folder of the Industrial Toolbox. Specifically the cli.c file features a hard-coded configuration that is sent automatically at run-time.

    2. The commands in the chirp configuration file are defined in the mmWave-SDK User Guide on page 18.

    3. Lastly, the TLV's are detailed in the mmWave Doxygen as part of the SDK. You can find it at the following location: C:\ti\mmwave_sdk_03_03_00_02\packages\ti\demo\xwr68xx\mmw\docs\doxygen\html\index.html
