CCS/AWR1642BOOST: AWR1642 Boost rev B CAN dbc file for messages interpretation

Part Number: AWR1642BOOST

Tool/software: Code Composer Studio

Dear all,

I know you have seen many asked questions from me, I m  trying to speed up my work on awr1642boost for a DEMO using CAN Interface. After solving many issues concerning can data over can bus lab, today I'm receiving classic CAN messages correctly but I need to understand and interpret CAN data. I'm looking for getting in addition of (X,Y) scatter plot the velocity of detected targets.

 

I'm wondering if someone here had generated the dbc file or had arrived to interpret CAN messages?

 

 

Thank you

    Hi,

    I assume that you are using the following demo:

    mmwave_automotive_toolbox\labs\lab0005_object_data_over_can

    This demo is based on the mmWave SDK demo v 2.1.0.4.

    The only thing that was updated was

    • configuration hard-coded. It is not through CLI as in the original SDK demo
    • output through CAN instead of UART as in the original SDK demo

    Knowing that, the documentation of the output data format provided in the SDK 2.1  applies for this demo.

    This documentation can be found in:

    Section:

    "Output Information Sent to Host"

    file:///C:/ti/mmwave_sdk_02_01_00_04/packages/ti/demo/xwr16xx/mmw/docs/doxygen/html/index.html

    The buffers sent are defined in "MmwDemo_dssSendProcessOutputToMSS()" see file

    mmwave_automotive_toolbox\labs\lab0005_object_data_over_can\odoc-target\dss\dss_main.c

    So, when you receive the CAN data, you need to first identify the magicWord header. This will be the beginning of the frame

    thank you
    Cesar
