AWR1642BOOST: How to connect the Module to FPGA?

Shabirahmed Jigalur

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: AWR1642, , DCA1000EVM

Hello everyone,

I am new to the mmWave sensor.  I am working on a project where I am responsible for the interface between the AWR1642 module to user FPGA(Specifically Xilinx-XYNQ-702 board).

We will be using three boards of AWR1642Boost to cover our required angles. I need to interface those three boards to FPGA and read the Data through my FPGA.

Can anyone suggest me what will be the best way to approach for this issue and what kind of interface I can use to connect AAWR1642 to FPGA?

p.S: I have DATA capture card DCA1000EVM. I tested it and read the raw data as per given in the guide. I know the card has lattice FPGA inbuilt but I want to connect to Xilinx Zynq FPGA.

Another question I have is, if I am able to access AWR1642 card then can I control its beam using my code dumped to FPGA?

Thank you

    Hello ,
    Are you trying to use the FPGA only for the raw ADC data capture? In that case you just need the LVDS interface from the 3 devices going to the FPGA. I assume you would be having your own application in the AWR1642 to send out the ADC data, if your application needs any kind of inputs that need to come from the FPGA then that is another thing to consider.

    Is there any intent to have some kind of synchronization of the three devices?

    regards,
    Vivek

    Hello Vivek,

    Thank you for your response.

    First, I want to connect the AWR1642BOOST EVM to Xilinx Zynq-7000 SoC ZC702 Evaluation Kit (www.xilinx.com/.../ek-z7-zc702-g.html). Do we get a 60 Pin HD connector to FMC? as I don't know how to connect to FPGA board.

    Next, after connection, my aim is to control the beam in AWR1642BOOST using my FPGA (so,  think there will be inputs coming from FPGA to EVM). Application for the EVM is developed by another group, my part is to give an interface between EVM and FPGA and give them a control to BEAM.

    Thank you

    Hello Shabir,
    We are not familiar with off the shelf cables connecting samtec 60 pin to FMC, you might need to look for it online. My guess would be you might have to build an adapter board yourself for that.

    Regarding the interfaces between the AWr1642 and the FPGA, you would have to discuss with the application group and understand the interfaces they plan to use in their applications and then appropriately provide those on your HW. As you know the AWR1642 is fully programmable and user could use different interfaces based on your application.

    Regards,
