AWR1843AOPEVM: Parsing format confusion

Part Number: AWR1843AOPEVM

Tool/software:

Hello,

I am using an AWR1843AOPEVM for development of rear side traffic survelliance on a vehicle. Looks like MRR demo is suitable for me. I am trying to transfer tracking data to a microcontroller via i2c however I am having difficulties about how this data is parsed. 

I used these resources but there some confusions.


Understanding uart data output format 

Structer here is Header(40bytes)-->TLV Header(type+length 8bytes) --> TLV Payload(detected points*16 bytes) + Padding

Here detected points includes X, Y, Z, Doppler

Where can I find the detailed description of Output Data Format for lab00007 Medium Range Radar 

Structer here is Header(40bytes)-->TLV Header(type+length 8bytes) --> TLV Payload(numDetetedObj + xyzQFormat + detected points) + Padding

Here detected points include speed, peakval, X, Y, Z

And as a question in this detected objects message how do I know which data is coming tracking, clustering or detected object 

Somehow I can't understand the correct format. Can you clarify it for me ?



Thanks in advance

  • Hi,

    The best way to understand how to parse the object data is to review the MRR matlab gui.

    Please check the GUI src files

    Thank you
