IWR6843ISK : Why, do we need the DCA1000? (Question about real time raw data capture)

Part Number: IWR6843ISK
Other Parts Discussed in Thread: MMWAVEICBOOST, IWR6843

안녕하세요, 저는 TI RADAR을 처음 사용하고 있습니다.

IWR6843 및 IWR6843 ODS, MMWAVEICBOOST, DCA1000이 있습니다. 이제 저는 RADAR의 원시 신호에 대한 몇 가지 프로젝트를 진행하고 있습니다.

내 프로젝트에서 IWR6843 시리즈의 원시 신호를 컴퓨터 또는 임베디드 보드 (알고리즘을 수행하기 위해)에 저장해야합니다. 이 상황에는 몇 가지 질문이 있습니다.

가장 먼저 궁금한 것은 DCA 1000이 필요한 이유입니다. UART 통신이 IWR6843에 존재한다는 것을 알고 있으며 RADAR의 원시 신호를 컴퓨터에 직접 저장하는 데 사용할 수 없기 때문입니다. 요약하면 IWR6843 또는 IWR 6843ODS로만 원시 데이터를 얻을 수 있습니까?

둘째, DCA 1000을 사용하여 실시간으로 원시 신호를 처리하는 방법이 있다는 것을 알고 있지만 정확한 데모를 찾을 수 없습니다. 링크에서 찾으려고했습니다.

dev.ti.com/.../node

하지만 데모가 어디에 있는지 구체적으로 알 수는 없습니다. 특정 데모의 위치를 ​​알려 주시면 감사하겠습니다.

진정으로

    Hello, I am new to TI RADAR.

    There are IWR6843 and IWR6843 ODS, MMWAVEICBOOST, DCA1000. Now I'm working on some projects on RADAR's raw signals.

    In my project I need to save the raw signals of the IWR6843 series to a computer or embedded board (to perform the algorithm). There are several questions in this situation.

    The first thing you're curious about is why you need the DCA 1000. Because I know that UART communication exists in the IWR6843 and it cannot be used to store the raw signals of the RADAR directly into the computer. In summary, can I get raw data only with IWR6843 or IWR 6843ODS?

    Second, I know there is a way to process raw signals in real time using the DCA 1000, but I can't find an exact demo. I was trying to find it in the link.

    dev.ti.com/.../node

    But I can't know specifically where the demo is. It would be appreciated if you could let me know where to find a specific demo.

    for real

    Response:

    Please note the difference between data type that mmWave sensor sends out:

    Raw Data =  RF signal from Per transmitter, Sent over the LVDS port of the device

    Post Processed Data sent by various demo  = information about objects, point cloud, FFT, tracks for people,  sent over uart, SPI, CAN etc

    DCA1000 + mmWavestudio helps you save Raw Data from TI's mmWave EVM on to the host machine for offline processing or algorithm develpment.

    It allows data to be collected at high speed and we provide software that run on device to enable this data out via DCA1000 interface over Ethernet to PC.

    The link you sent used demo that sends our post processed data is that what you would like to save to file and process?

    Hope this helps.

    Thank you,
