IWR6843AOP: Sensor configuration over CAN

Adam Koutny

Part Number: IWR6843AOP

Hi,

I am using modified firmware based on the OOB demo. I have made adjustments to replace UART communication with CAN and implemented hard-coded sensor configuration.

For my application, it would be beneficial to configure the sensor via the CAN interface, at least for a portion of the full configuration. Specifically, I plan to operate multiple sensors on a shared CAN bus, and each sensor should have a unique ID for CAN message identification.

If configuring over the CAN interface is not feasible, I may have to compile firmware separately for each sensor, with the only difference being the ID.

Is this possible?

Thank you,

Adam

Hi Adam,

It is possible to configure the IWR6843AOP over CAN. You will have to build the firmware to replace the UART based CLI to CAN. You can have a ID based network to filter out CAN messages and configure the respective sensor

Which interface do you intend to use for the point cloud output data? CAN bandwidth may not be sufficient for that

Hi Abhishek,

Do you have an example of replacing the UART-based CLI with CAN?

I intend to use CAN-FD for the point cloud output data. I hope it will be sufficient.

Thanks, Adam

Hi Adam,

We do not have an example of CLI sent over CAN.

You can refer to the following CAN driver example for porting onto your setup

mmwave_sdk_03_06_00_00-LTS\packages\ti\drivers\can

CLIs you may have to extract from the demo
