AWR6843AOPEVM: AWR6843 data format

Part Number: AWR6843AOPEVM

Hello TI community,

I finally settled for my automotive internship project on the AWR6843AOPEVM board. However through documentation many things remain unclear.

Two data are mentionned, basically the ADC raw data and the radar output data. I'd like to know the link between the two and more information please.

For radar output, I found some doc about UART data format (link : UART data format ), however in my case I'd like to work with the CAN interface, can I have the same TLV structures as in the UART ? or do I have to proceed differently.

Thanks and regards,

Lilia.

    Hi Lilia,

    ADC data is the unprocessed data from the radar frontend's ADCs. To capture this data reliably, we direct people to using the DCA1000 with documentation here. 

    If you do want to leverage our on-chirp processing, you can utilize the available drivers provided the in the SDK. We provide example/test code for each driver. To leverage CAN, SPI, rather than UART (which our demos all leverage out of the box), you will just have to modify the source code provided to leverage the different hardware drivers. In all of those cases though, the post-processed data will still have the TLV format, unless of course, you modify that in the source code too. You will likely also have to check the schematic to figure out the necessary EVM switch configuration to break out the peripherals of your choice from the mux tree.

    Regards,
