AWR1843AOPEVM: 3D People Counting demo on AWR1843AoP EVM with point cloud output via CAN Interface

Part Number: AWR1843AOPEVM
Other Parts Discussed in Thread: AWR1843AOP, MMWAVEICBOOST

Hello,

I wanted to migrate 3D Pepple counting demo on AWR1843AoP EVM and get the point cloud ,tracker output via CAN interface instead of UART:

Is this feasible. If yes, can you suggest some links for migration and CAN implementation ?

Also I am confused with the virtual antenna geometry configuration for AWR1843AoP (antGeometry0, antGeometry1,  antPhaseRot). Can you provide information for the same.

Thanks and Regards

Vignesh

    Hey Vignesh,

    It should be possible to migrate the 3D People Counting Demo to the AWR1843AOP EVM. In terms of adapting the existing code, you can start off by looking over the mss_main_18xx.c file provided under <RADAR_TOOLBOX>\source\ti\examples\Long_Range_People_Detection\src\6843. This provides some of the changes required to run the demo on the 1843, but you will have to change what device libraries and header files are used for compilation.

    As for the CAN implementation, I would recommend reviewing the documentation for the CAN driver under <MMWAVE_SDK_3>/packages/ti/drivers/canfd/docs/doxygen/html/index.html and going over the Object Data Over CAN example in the Radar Toolbox. The first resource is good for understanding the setup process for CAN and the latter resource can help you better understand how to use CAN in a broader context. You can also look over the source code for driver test unit in canfd driver folder

    For general information on the virtual antenna geometry configuration, you can look over p.4 - 6 of CPD with Classification Setup Guide.

    Let me know if you have any other questions.

    Regards,

    Kristien

    Hello Kristien,

    Thanks for the information.

    I would also like to know the additional hardware required to interface the AWR1843AoP EVM to a Windows PC for testing.

    I purchased a PCANFD-USB adapter. Please let know about the hardware requirements.

    Regards

    Hey Vignesh,

    If you are going to be doing in-depth development and testing, I would recommend getting a MMWAVEICBOOST which will allow you to debug your application in the CCS debugger using the XDS110 and give some extra connectivity such as power over Ethernet and Wi-Fi. This board is also required if you would like to do raw ADC capture using a DCA1000. However, this will depend largely on what application you're hoping to develop. As a minimum, I would say that you should pick up the MMWAVEICBOOST as it is much more difficult to develop an application without access to the CCS debugger. If you end up implementing your own radar algorithms, getting raw ADC data from the DCA1000 can be useful for tuning the algorithm's performance.

    Let me know if you have any other questions.

    Regards,

    Kristien
