AWR1243: How to control more than 2 cascade EVM from PC

Part Number: AWR1243

Hi,

 

I have some queries about AWR1243P + TDA2x cascade EVM from a customer.

I would like to connect more than 2 cascade EVM to PC and control them in parallel from PC.

 

From what I understand:

- Only on EVM can be controlled from “mmWave Studio”.

- Only one “mmWave Studio” can run on PC simultaneously.

 

So I wonder if any APIs disclosed to control EVMs from PC.

 

Thanks & Regards,

-Shibata

    Hi Shibata,

    I request you to go over the cascade app-note to get the hardware connection for 2-chip cascade setup.

    It requires LO, DIG_SYNC, OSC_CLK connection from Master to Slave device and length matching for 20GHz LO.

    I'm not sure if connecting two EVMs can provide full hardware functionalities of cascade setup. So for cascade you must need to have two AWR1243P on the same PCB having all required lines connected and further connection with TDA2x.

    You are right that existing mmWave Studio can control only one EVM. We are in the process of next version of mmWave Studio release which can connect to TDA2x+AWR1243P cascade setup over ethernet. Stay tuned to ti.com for the release announcement.

    Hi Jitendra,

     

    Thanks for your comments.

     

    Please find an example block diagram.

    (1)    EVM1 and EVM2 are independent cascade setup. So I don’t need to sync these EVMs.

    (2)    However, I want to control both EVM1 and EVM2 from one host PC

     Do you mean that more than 2 TDA2x+AWR1243P cascade setup can be connected to one mmWave Studio in next release?

    Hi,

    Next release version of mmWave Studio can control only one TDA2x over Ethernet not two.

    But based on you setup diagram, you can use different interface connection with TDA2x to connect and control 2 TDA2x (having 2-set of AWR1243P on it) from PC.

    You can control two TDA2x over UART which will be emulated over UART-to-USB to COM port of PC.Both of TDA2x will provide different COM port, so now you can send commands over UART to both of TDA2x which further control/configure AWR1243 devices.

    Another option to do over network connection (IP-address from single PC) instead of UART. Vision SDK provides default example for UART and Network connection.

    Hi Jitendra,

    Thanks. I will look into PROCESSOR SDK VISION (RADAR).
