AWR1843BOOST: some detailed information about the board

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843

Hello, 

I have some questions about the AWR1843BOOST board:

1- Is this board capable of capturing and visualizing the radar raw data? Does it enable access to the raw data?

2- If the AWR1843BOOST is capable of raw data capturing, can it do it by itself or it needs another board for this purpose like the DCA1000??

3- Does this board allows raw data processing in real-time during run time or the processing of the data can only be carried offline? which programming language is used in this case?? still the LAU scripting?

    Hi

    I encourage you to check the mmWave FAQ

    https://e2e.ti.com/support/sensors/f/1023/t/595725

    Here is a summary

    • AWR1843BOOST requires DCA1000 to capture raw data
    • Data can only be captured and processed offline.
    • We have a new tool, a CLI mmwave studio version that you could use. Please review it on the TI Resource Explorer (dev.ti.com), mmWave Software, Platform Toolbox

    Thank you

    Cesar

    Dear Cesar,

    Many thanks for your reply.

    At the start of your reply, you mentioned that the AWR1843BOOST requires DCA1000 to capture raw data. However, when looking at the datasheet of the board it seems that it has its own MPU and DSP processing units already implemented in the board. This means that the AWR1843BOOST should be able by itself to capture and process the raw data at run time.  

    Moreover, on the support page(provided in this link: https://e2e.ti.com/support/sensors/f/1023/t/927257 ),  in the last post, I see "For the other platforms (1843, 6843…) the processing is performed in real-time on the processing engines (DSP or HWA) integrated into the device. The processed output is sent via UART to the PC and displayed with a GUI." So it seems that the processing is made directly on the board, and only results are sent back to the pc, but not raw data. 

    So, when you say "AWR1843BOOST requires DCA1000 to capture raw data" I feel like there is a contradiction in the information,  which makes me a bit confused. Can you please clear this idea to me.

    Best regards

    Hi,

    Your understanding is correct. Sorry for the confusion!

    I think the confusion comes from the use of the term "capture"

    Please read below and let me know if there are any questions

    Thank you

    Cesar

    Usually there are two main use cases for AWR1843

    Use case #1

    Capture Raw data to a binary file on the PC. Use Python or Matlab or any other high level language to process the raw data for algorithm development

    This use case requires DCA1000

    Use case #2

    Process the Raw data on the target (using the DSP or HWA) Send the object data (x,y,z,velocity ...) to a host using one of the interfaces: UART, SPI, CAN...

    In this use case the user does not have access to the Raw Data because the data is processed at run time. So there is no actual "capture" of the data.

    This use case does not require DCA1000.

    Hello,

    Many thanks for your clarification. It was much of help for me to clear the confusion.

    So based on your reply, I understood that even with AWR1843BOOST capturing the raw data is only possible when it is used with the DCA1000. However, when the AWR1843BOOST is used alone only the data after processing is visualized and access to the raw data before processing is not possible.

    Please confirm if my understanding is indeed correct.
