CCS/IWR1642BOOST: IWR1642BOOST raw data access protocol

Part Number: IWR1642BOOST

Tool/software: Code Composer Studio

Hi, experts:

I use IWR1642boost board and try to capture raw data.

my question is:

1. the EVM boards from Ti generally are not size matched.

2. I try to design my own FPGA board with desired size or may integrate the front board together.

3. I can connect all the 60pin signal to my own FPGA board.

4. does this boost board have any protocol or other rules to get the raw data?

    Hello,

    TI EVM board are targeted for generic many application and we have to comply with the booster pack standards, hence it may not be form-factor in the size. You could develop your own form-factor board.

    On DCA 1000 we have two interfaces control interface and capture interface. Control interface (SPI, UART) would come from FTDI chip and you would need corresponding FTDI drivers to operate SPI and UART interface protocols. On the high-speed interface side there is LVDS transmitters from our device which would be interfaced to FPGA device. In DCA1000 we use Lattice FPGA to capture raw ADC data. Are you planning to re-use the FPGA as is? If yes, then you may follow the flashing instructions provided in the userguide www.ti.com/.../spruij4.pdf

    Are you planning to reuse the mmWave studio or planning to write your own application for control path and Data-capture paths?

    Thanks and regards,

    Hi， CHETHAN
    Thank you for the quick responce.
    I already have a FPGA board which using Cyclone V FPGA. What I hoped is to interface my board with IWR1642boost board and capture the raw data. my board has enough GPIO's and is easy to be connected to IWR1642boost board.
    I am good at HDL code and just need some instruction.

    Currently, I have a mmwave-devpack, a TSW1400 board and two IWR1642boost boards. I can capture raw data from the three board combination, but they are inconvenient to use.

    Zen,

    Thank you for your response. You may want to review DCA1000 based data capture system which eliminates mmWave-devpack and TSW1400 board with DCA1000 single board. IWR1642BOOST and DCA1000 could be used for the raw data capture. You could refer to below training video.

    If you still want to go with the custom solution, then It's best for the control path UART (RS232TX/RX) for the control interface and SPI interface through the FTDI ports as mmWave studio look for the FTDI drivers to communicate the APIs to mmWave sensors.
    For the capture interface you could use the Cyclone V FPGA.

    Thanks and regards,
