Part Number: IWR1443BOOST

Tool/software: Code Composer Studio

hi,

   the mmwave visualizer can give the x,y,z of certain object, and how can i get that information from other demo codes, for example, vital_signs code?

thank you ~

    Hi ,

    Please see this link and download the projects:

    Then you can see the projects in the "Demo" folder and "Labs" folder.

    Regards,

    Hello,

    The range information can usually be found by searching the main.c file for 'range' for the given demo code. For example, in the Vital Signs demo, starting on line 468 of the main.c file you can see the rangeBinIndex is used to get the real and imaginary parts of the range bin as well as the magnitude of the current range bin and the strongest current range profile.

    Regards,

    hi,

     I can find the vital_signs project and run that, but I want to find information to compute the 2D / 3D location of certain object,the range profile can be used to figure the distance between EVM and object, how to get the other dimension distance?

    thank you~

    Hello,

    If you want to compute the distance of various objects, it may be better to use the out-of-box mmWave demonstration that is supplied with the SDK and pre-programmed in the new boards. You may then refer to this post that points to documents giving the detailed data format output by this and some other demonstrations.

    Thank you,
    François.

    Hello,

    Only one TX and RX are used in the Vital Signs demo, thus the x, y, z information is not obtained. To obtain this information you would have to modify the profile configuration to used multiple RX and TX antennas and modify the code to get this information. Francois is correct, the mmWave Demo has been designed to do this already and is your best option for obtaining the x, y, z information.

    Hello,

       thank you very much~

    and can you give me some advices on changing the code to get the x,y,z information? or can you tell me how to use two receive antennas by changing the vital_signs code?

    thank you~

    Hello,

    Please refer to my former answer. The vital signs demo is *not* suited for getting x/y/z information of the objects the radar senses. Please re-program your board with the mmw demo provided in the SDK and as instructed in the SDK manual, section 3.1. The format of the data output by the radar is described in this document; you will get directly x/y/z from there.

    Thank you.
    François.

    thank you, and if so, can i use two EVM at the same time on one computer? how ?

    Hello,

    You may indeed connect several EVMs to the same host. They will be seen as different COM ports. Then you may configure several instances of the mmWave Demo Visualizer, or your own host application, to use different COM ports.

    Thanks,
    François.
