MMWCAS-DSP-EVM: ADC data processing reference code

Andrew Kramer

Part Number: MMWCAS-DSP-EVM
Other Parts Discussed in Thread: AWR2243, MMWCAS-RF-EVM, AWR1243, TDA2

Hello!

I'm working with the MMWCAS-DSP-EVM paired with a MMWCAS-RF-EVM using AWR2243 radar devices. I have successfully run the mmWaveLink_Cascade_Example from MMWAVE-DFP-2G version 2.2.2.1. I would like to write my own application which continuously streams ADC data from the AWR2243 devices to the host computer over ethernet rather than logging it to the SSD on the DSP-EVM.

I think I have a good idea of how to do this on the host computer, but I would also need to modify the code running on the DSP-EVM and I can't find any information on how to do that. Is there any documentation on how to write and build applications to run on the DSP-EVM? Also, it would be very helpful if I could refer to the source code for the application that runs on the DSP-EVM and communicates with the mmWaveLink_Cascade_Example running on the host computer. The binary for that application came pre-installed on the DSP-EVM's micro-SD card, but I haven't been able to locate the source code. Could you tell me where to find that source code?

Thank you so much for your help!

    Hi,

    The data capture solution is provided for ease of use as a "black box" and source code is not provided.

    As was discussed in other threads there is a demo that runs on the TDA2x that could be used as a starting point.

    This demo has been implemented with AWR1243 cascade kit. So the first step would be to upgrade to AWR2243.

    There is a patch provided in the mmWave FAQ to help with the porting.

    As was mentioned previously the team that developed the original target code is no longer available, therefore the code is provided "as is" with no support

    thank you

    Cesar

    The AWR1243 + TDA2 cascade real time demo please see following TI Design

    For porting to AWR2243,

    Please see the mmWave FAQ Cascade, Item #13

    Hi Cesar,

    Thanks so much for the references. However, the file you linked for the AWR1243+TDA2 real time demo just takes me to the product page for the TIDEP-01017 board. Could you be more specific about where I can find source code for the real-time demo you're referring to? Also, with this demo will I still be able to control the DSP-EVM using the mmwl_port_ethernet and mmwlink libraries? Or will it use different libraries for communicating with the host machine?

    Thanks again!

    Please see the Software link at the bottom of the TIDEP-01017 page

    You will need to download the PROCESSOR-SDK-RADAR. v3.08.00.

    This demo still uses the mmwlink libraries running on TDA device

    Thank you

    Cesar
