IWR1843BOOST: IWR1843BOOST

Part Number: IWR1843BOOST
Other Parts Discussed in Thread: IWR1843, MMWAVE-SDK

Hi, 

I am using IWR1843boost and DCA1000. They are successfully connected and I can see 4 plots in mmwave studio. My question is that how can I be sure that data is being transferred from sensor to DCA1000 and how do I have to configure the boards to detect motion of objects in mmwave plots?
My second problem is that DS1 Nerr_OUT on IWR1843BOOST glows. What should I do?

thank you in advance

    Salam Fereshteh,

    If you are getting data in via mmWaveStudio then you are 100% certainly getting the raw data from the DCA1000. This is because unfiltered, unprocessed, dumped ADC data requires transfer speeds so high that Ethernet is required. This is why the DCA1000 is needed in the first place. 

    The purpose of this raw ADC data capture is to use scripts to import the data into programs such as MATLAB so that one can write and create processing algorithms of their own to do custom object detection and any other type of processing they would like.

    If you want to simply get object detection, you can follow the instructions of one of our examples found in the Radar Toolbox on the TI Developer Zone. For IWR1843 you can start with the Out of Box demo, and I recommend using the Applications Visualizer for a 3D view of the environment and the objects detected within it

    Follow steps 1-3 above then go to the Applications Visualizer User Guide

    Salam Pedrhom, 


    Thanks, I followed the instructions.
    In my computer, CLI COM port : COM5 and Data Com port : COM7
    1. With the web-mmWave Demo Visualizer, COM5 is connected, but COM7 is not connected and is waiting for data. I tried with all versions, and I didn't forget to set SOP (SOP0=ON , SOP1=OFF , SOP2=OFF ). What could be the problem?


    2. In mmWave Industrial Visualizer, I select a .cfg file for example very fine motion detection, after start nothing happens. What could be the problem?


    3. when saving the configuration in mmWave Studio, it can only be a .XML file. Can it be a .cfg file and be imported into mmWave Industrial Visualizer ?

    Thanks in advance for your response.

    Salam Fereshteh,

    1. The web based mmWave Demo Visualizer is only compatible with the Out-of-Box binary firmware image. This is the .bin file you can find in the MMWAVE-SDK package (https://www.ti.com/tool/MMWAVE-SDK#downloads) at C:\ti\<MMWAVE-SDK>\packages\ti\demo\xwr18xx\mmw\xwr18xx_mmw_demo.bin. Ensure this is the binary flashed with switches set to flashing mode, then switch back to functional mode via SOP switches and try this visualizer again.

    2. What exact .cfg were you using with which exact binary? 1843 is one of our generation 1 devices, and many of our newer demos do not support it. Check the Examples Overview page in the Radar Toolbox to see the demos that are compatible with it https://dev.ti.com/tirex/explore/node?a=1AslXXD__2.10.00.04&node=A__ALa0NkZs5b5KkC0eLj0oEg__radar_toolbox__1AslXXD__2.10.00.04.

    3. mmWaveStudio is for capturing unfiltered, unprocessed, dumped ADC data straight from ADC buffer via DCA1000. This will only give RxkIn and RxkQn data, which can then be used to create custom processing algorithms via importing this data to tools such as MATLAB. This is only recommended for very advanced and experienced users. That being said, there is currently no way to directly import/translate a .XML or .JSON file made for mmWaveStudio into an equivalent .cfg file.

    Hope this helps, overall with the 1843 I recommend playing with Out of Box demo to start, with the Applications/Industrial Visualizer (the web browser one is okay too, but more limited).

    Best Regards,

    Pedrhom
