AWR6843AOPEVM: Is there any method for me to send the message from dss to the UART?

Hi Webb,

If you are using 6843AOPEVM, you should be able to leverage CLI_write (found in <SDK_INSTALL_DIR/packages/ti/utils/cli/src/cli.c) to dump desired data to computer. You can then use TeraTerm or similar utility to view output. You would just need to select the port number named "User Uart" or "Enhanced" from your Device Manager. 

I mentioned the hardware because you would need a USB to UART converter, but the XDS110 on the EVM takes care of this.

Hi! Kevin Ortiz!

Thank you for your reply.

The process:

(1) Can build the css bin file and flash the bin file to the radar AWR6843AOPEVM.

(2) Can connect the USB to the radar and get the message from the radar. The data port gives us the binary message. Can put the radar config to the radar through user port.

(3) Already get the tlvs and knowing the position data, the azimth, ele, range and snr.

I would like to dump the values in pdataIn from radarProcess.c in the dss/common folder to the data port. Not the user port.

Can you help me?

Thank you!

Best regards,
Webb

Hi Webb,

Thank you for the clarification. I'm sure this is possible, but I haven't done this myself. Let me check internally to confirm on recommended procedure.

Hi Webb,

Page 9 of the SDK User Guide explains how to use the data_port UART to view the data being output by the device. The User Guide can be found at <SDK_INSTALL_DIR>/docs/mmwave_sdk_user_guide.pdf

The lab you are using outputs its data via the data_port UART. Then it would be a matter of using TeraTerm like before mentioned and selecting the "Data" or "Standard" port. The baud rate here should be 921600.

Hi! Kevin Ortiz!

Fortunately, we'd switched the project to the single_row_occupancy_6443.

We can get the RangeProfile much more easily than other projects.

I've successfully let the UART dump the RangeProfile by tuning the parameters of radar config.

Thank you!

Best regard,
Webb
