AWR1843BOOST: Resource Explorer Ready-Codes Selection

AWR1843BOOST: Communication

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843

Hi there,

I'm working on AWR1843BOOST Evaluation Module and I'm studying with resource explorer codes (/software/mmWave Sensors/Automotive Toolbox (3.4.0)/Labs/Medium Range Radar) Accordingly, I would be very grateful if you could answer my questions below.

  1. If I understand correctly, CCS Project - DSS codes for AWR1843 sensor, CCS Project - MSS codes for TM4C1294NCPDTT3 microcontroller. Am I right?
  2. I want to transfer distance and speed data by communicating with the TM4C1294NCPDTT3 microcontroller on the AWR1843BOOST development board and another microcontroller from outside with minimal changes in the code. I don't need to connect it to a computer, to simulate it.
    1. If I am not going to communicate with the computer and simulate it, which parts of the code should I remove? 
    2. If I am going to communicate with another microcontroller, which communication protocol should I use?
    3. Do you have an example used in the TM4C1294NCPDTT3 microcontroller for the communication protocol you suggest?
  3. Can you summarize which code file in CCS Project - DSS or CCS Project - MSS was written for which functions?

    Hi,

    Could you let us know why you are interested in Labs/Medium Range Radar and not the mmwave SDK oob demo? For MIMO use case the mmWave SDK demo has more features and more documentation.

    If you need to use the Beamforming mode, than you would have to use the MRR demo.

    Answer #1

    AWR1843 integrates a DSP (DSS) and R4F (MSS). The CCS projects are for the DSP and R4F

    Answer #2

    #2a The code should not change

    #2b The demo supports UART, but you could also update the demo to use SPI, we can provide an example

    #2c Please submit a new e2e thread for the TM4C1294NCPDTT3 team

    Answer #3

    Could you please provide more details about this question?

    thank you

    Cesar

    Hi Cesar,

    1) There is AWR1843 and TM4C1294NCPDTT3 microcontroller on the AWR1843BOOST development board. I have uploaded the images. You can see.  I don't have any extra effort to connect AWR1843 and TM4C1294NCPDTT3 microcontroller. I'm just trying to figure out what the processor on it is for. What does the TM4C1294NCPDTT3 microcontroller do on this board?

    2) The demo supports UART and sends DATA constantly, I don't need to change anything. If I'm not mistaken. So, do you have a document of the protocol used in order to make sense of the sent data in the other microcontroller? 

    3) When I asked you before, you said that I could benefit from the documents in Labs. What is the mmWave SDK demo? Where can I reach? What is MIMO mode?

    4) There are two separate software files in the Medium Range Radar file. CCS Project - DSS and CCS Project - MSS. As far as I understand from reading the User's Guide and Getting Started Guide documents, I need to install both of them on the development board. I was curious about the differences between DSS and MSS, which commands are shared this way and why.
