AWR1642: Inquiry one the AWR1642 Sending Its Readings to a Separate Processor

Denis Nakazawa

Part Number: AWR1642

Hello, 

I would like to build an application using the AWR1642 mmWave sensor. I understand that it contains a programmable Cortex processor and a DSP as part of its package, but I was wondering if it's possible to have the programmable Cortex send out the AWR1642's readings over some communication protocol (UART, SPI, I2C, etc.) to an external processor? I am looking at the technical reference manual and errata sheet for the AWR1642, but given that I'm very new to working with this topology of embedded applications, I'm not quite able to determine the answer to my question on my own. 

Thank you in advance for any help!

Sincerely, 

Denis

    Hi,

    Yes, this is possible.

    If you already have an AWR1642BOOST board, please run the mmWave SDK demo. Information on how to flash and run the demo is provided in the mmWave SDK UG

    C:\ti\mmwave_sdk_03_05_00_04\docs\mmwave_sdk_user_guide.pdf

    This demo sends the detected point information over UART to the PC.

    It is also possible to use the SPI. We have an internal demo that sends the detected point information over SPI. We can provide this is example to you if you wish

    thank you

    Hi Cesar, 

    Thank you for your reply. 

    I would greatly appreciate a copy of that demo, if possible. 

    Thank you!

    Hi,

    I sent you a link with the example. Please diff with 684x mmWave SDK OOB demo to understand the changes.

    These changes can be applied to any of the other platforms supported by the SDK OOB demo

    thank you

    Cesar
