AWR1642BOOST: Data real time transmission with DCA1000

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: AWR1642, AWR1443

Hi, I am planning to use AWR1642 BOOST with DCA1000.

Main purpose is data logging with other sensors, so i need to stream data real time not by saved data.

So is there any method to stream data  (raw, FFT, Heatmap, object data/ could be selective or at once) through connection with PC(such as matlab or C code) via LAN connection in real time? 

And also if it is just to transmit FFT or heatmap data, which one is better for use? AWR1443 or AWR1642

Thanks

    Hi,

    The DCA1000 is used for capturing raw ADC data from the AWR1xxx devices. The AWR1642 normally consumes the raw data internally and processes it on the internal DSP and only the processed results are sent out.

    If you only want the raw ADC data, then you can indeed use the DCA1000 to stream the data to a PC.
    However, if you want the processed data, then you cannot use the DCA1000 to achieve this. You could use the PC directly and read the data over the UART interface as it is sent out.

    The choice between the AWR1443 and the AWR1642 depends on what you want to achieve. The AWR1443 does not have a DSP but only has a hardware accelerator. The AWR1642 has more memory and additionally a CAN-FD interface. The AWR1443 does have an additional TX antenna.

    Please refer to the following page for a comparison between the devices.

    Hi,

    Thanks for really fast reply.
    What i confused is that at forum e2e.ti.com/.../2790328
    the reply said that i need to use DCA1000 to send data (user or raw adc data) over Ethernet from the device.
    But as you said above any other data except raw ADC data could not transmit through DCA1000 board.

    Then DCA1000 board is just to send raw ADC data through ethernet? Is there any method to transmit other data such as FFT or object data via ethernet?. If it is not possible how can i stream those data through UART to PC with multiple AWR1642?

    Best Regards,

    Hi,

    The other reply is correct. It is possible to send both user data and raw data using the DCA1000.

    This is supported from mmWave SDK 2.1 onwards. The demo included in the SDK shows how to send this user data over the LVDS interface.
