IWR6843AOP: How to transmit radar configuration to IWR6843AOP via CANFD

Lim

Part Number: IWR6843AOP

Tool/software:

Hello, experts.

I am currently working on a project involving the IWR6843AOP and I am planning to implement CANFD based on the People Tracking demo. Specifically, I have some questions regarding the usage of the CANFD interface on the IWR6843AOP.

1. CAN Interface Utilization: The IWR6843AOP features a single CAN-FD interface. I would like to confirm whether it is feasible to use this single CAN interface to both transmit radar configuration to the IWR6843AOP and receive output data from it . If possible, could you please provide guidance or reference materials on how to achieve this?

2. Implementation Guidance: If the above setup is feasible, I would appreciate any insights or step-by-step instructions on the implementation process. Are there specific considerations or best practices we should be aware of while configuring the CAN interface based on the People Tracking demo?

Thank you for your support.

    Hello,

    Thanks for posting your questions on CAN! Yes, you could transmit a radar configuration to the IWR6843AOP and receive output data from it. While we don't have material on configuring the device over CAN, most demos use a CLI UART task to read and parse commands over UART. You could theoretically replace the UART reads with CAN reads instead. These CLI files are spread throughout a project, but it depends based on which project you are using.

    Speaking of which, I would highly recommend looking over the CAN integration user guide and project from the Radar Toolbox which goes over an example project that transmits processed data and can receive CAN data. The "CAN Integration for SDK 3 Devices" section goes over how to add CAN to an existing project, how to use the CAN driver, and some other caveats to be aware of. 

    Hopefully this gives you a good place to start, but let me know if you have any other questions.

    Regards,

    Kristien
