IWR1443BOOST: Slow speed from data capture board to PC

Bo Wang69

Part Number: IWR1443BOOST

I am using IWR1443 BOOST radar board to capture the radar signal and TSW1400EVM board to transmit the collected data from the board to PC. However, the data transmission speed is very slow from the board to PC using a USB port. I am trying to realize a real-time system, so I am writing to ask if there is any solution to the problem and If there is any better data capture board with high data transmission speed to PC? Thanks!

    Bo,

    Unfortunately there is no real-time solution at this time.

    That said, you could use the DCA1000 capture card with mmWave and stream the data over Ethernet, you would need to do several thing in order to achieve this.

    1)     You will need to use mmWave studio to set up the device and have it running

    2)     Your frame in mmWave would need to be set to "0" this way you will continuously stream the data.

    3)     You would need to "intercept" data packets somehow

    1. you can monitor Ethernet traffic with Wireshark for example
    2. data will come in packets (UDP) that you will need to:

                                              i.    re-order if data if received out of sequence

                                             ii.    pad with 0's if corrupt or missing data

                                            iii.    handle dropped packets

    With that said you will be on your own as far re-ordering, dropped and padding packets, but in my experience I have rarely had the mentioned issues.

    Hope that this can help you make a decision.
