IWR6843ISK-ODS: MMWave Inquiry

Part Number: IWR6843ISK-ODS

Hi,

Good Day. I have a customer who is working with IWR6843ISK-ODS. Please see below for his query for your reference. Thank you very much.

I'm working with a mmwave sensor and I wanted to ask about its data communication over a serial port when I read the serial port data what exactly are the numbers I get? or what resources could I use to find out about this. I just want to make sure that my questions is understood. I'm getting raw data from the serial port I believe, so it's just outputting a list of numbers to the console. Not with a visualizer.

Best Regards,

Ray Vincent

    Hello

    Can you please help us understand the below:

    1. What steps did customer follow after they received the board  -  Every demo from TI   discusses how to use the demo and describes the out put on gui.  Additionally the data format for each demo is explained in TLV format.

    We would really like to know what Guidance was provided to user to evaluate the mmwave EVM which allowed the user to run the demo but did not give information  that is listed above.

    2. Please help us understand the intent of the evaluation or which application/use case is this EVM being tried for. This will allow us to point you to correct demo.

    Thank you,

    Vaibhav

    Hi Vaibhav,

    Good Day. Please see below the response of our customer to your reply. Thank you very much.

    After receiving the device I successfully ran the people counting demo visualizer. However my end goal is to run the board from a “microchip” microcontroller (programmed in C), so I can’t rely on the visualizer. Before attempting to program the microcontroller, I wanted to run the mmWave from a serial port on my computer but without the visualizer. This is so that I could see and learn what to do with the raw data from the mmWave. I found a third party Python script to accomplish it however the code ran with errors, and I still didn’t fully understand the data. Let me know if any additional information is required.

    Best Regards,

    Ray Vincent

    Hi, 

    This is possible! Once you have flashed the OOB demo do the following 

    1. Open trrraterm or any other COM port utility and connect to the two COM ports "Control" and "Data". Refer to SDK users guide for detailson identifying the COM ports. 

    2. On the "control" COM port hit enter key. This will show a command prompt as follows - mmwDemo:/>

    3. send the profile config file. Note: you may need to add delay after each line or after each character (which can be generally be configured from terraterm port settings).

    4. Capture the binary data on the "Data" COM port

    Hope this helps!
