AWR1843BOOST: Possibility of getting a ADC raw data located at a 50~100m range with Raspberry Pi + DCA1000

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: DCA1000EVM

Hello TI expert!

I used to utilize 'mrr_config_chirp_design_MRR80.h' for taking the position and range rate data for tracking objects.

And now I am thinking of getting a heat map from AWR1843BOOST radar. 

I went through the forum threads for making heat map and it seems like it would be much easier to have DCA1000 board for getting ADC raw data.

So I am thinking of getting a new DCA1000 board for now and I want to know some details of this board before I purchase. 

(1) My question here is that is it possible to get the ADC raw data while taking position / range rate data at the 50~100m range objects with using DCA1000 board?

Specifically, I would like to know if I can take the both the ADC raw data from DCA1000 and processed data (position, range rate etc) at the same time once I burn 'xwr18xx_mrr_demo.bin' on the AWR1843BOOST board.

(2) Another question is that I am not sure if I can extract the ADC raw data by using Raspberry Pi.

My customized python code can get the hexadecimal data from the UART port on Raspberry Pi but is it also possible to get the ADC raw data by using customized python code on Raspberry pi + AWR1843BOOST + DCA1000?

Thanks for your help.

    Hi Hongjoon,

    Please find my responses as follows:

    1. Yes. The DCA1000 is a board that takes LVDS data streamed from the device and sends it out via ethernet such that it can be captured by a host that supports the same. What the radar sees is determined by how you configure the AWR board.
    2. DCA1000 is one way by which you can obtain the ADC data. If you have ethernet support on the Raspberry Pi, you should be able to intercept all data sent by the DCA1000EVM on it.
