Hello,

We’re looking to get the cascade radar eval kit (RF-EVM / DSP-EVM) integrated into ROS (running in Linux) so that we can do some sensor fusion of it with a camera and lidar feed. The main issues I can see with this are:

How to communicate with the TDA2SX processor on the DSP-EVM board to enable data capture without mmWave Studio? Is there any example source code available for this? I know that for the DCA1000EVM data capture board that is used to capture ADC data from the single-radar chip eval boards there is an application available in Windows/Linux to control this without mmWave Studio – http://e2e.ti.com/support/sensors/f/1023/t/856054?-FAQ-Raw-ADC-data-Capture-from-mmWave-Sensor/ Q11. Also there's sample code in the rf_api.h header file supplied with mmWave Studio, however I'm not aware of anything similar for the cascade radar though.
How to communicate with the TDA2SX SoC on the DSP-EVM board to enable setup of the 4 x AWR1243P chips on the RF-EVM board without mmWave Studio? Is there any example source code available for this? For the single-chip eval boards (e.g. AWR1243BOOST) there is the mmWaveLink example source code (using mmWave Studio dll file) available in the Device Firmware Package that can be used to set up the AWR1243 chip over the USB-SPI link enabled by FTDI chip on DCA1000EVM board. Again I'm not aware of anything similar for the cascade radar though.
Transferring of files from the SSD on the DSP-EVM board onto the PC/laptop is very slow, can this be speeded up in some way to make the capture closer to real-time or at least with lower latency?

I'm thinking we'll have to just write our own firmware for the TDA2SX processor to do (1-2) above, which is what we'd intend to do long-term anyhow but just would be good if there was a Linux-compatible solution for demos in shorter-term.

Best regards,

Peter.

Hi,

Please take a look at the following TI Design. It provides a run time demo that does not use mmwave studio

thank you

Cesar

Hi Cesar,

I don't see where the run time demo that runs without mmWave Studio can be found - we have both boards in the cascade imaging radar kit you link to (RF-EVM and DSP-EVM) but as far as I'm aware the only way TI provide to interface with the kit is mmWave Studio, which communicate with the TDA2SX host processor over USB (we've been using the mmwave cascade user guide here to get up and running - http://software-dl.ti.com/ra-processors/esd/MMWAVE-STUDIO/latest/index_FDS.html). We can run the demo using this ok but as I mentioned this is far from real time, i.e. you have to capture ADC data to the SSD and then transfer to PC for external post-processing in MATLAB. Where is the run time demo you mention?

In this thread from November you stated that 'The cascade imaging radar kit uses mmWave Studio utility which is supported only in Windows' - http://e2e.ti.com/support/sensors/f/1023/t/860060?TIDEP-01012-Continuous-data-streaming-for-MMWCAS-DSP-EVM-and-MMWCAS-RF-EVM.

Does the PROCESSOR-SDK-RADAR for the TDAxx processors have support for real time streaming of ADC data? http://www.ti.com/tool/PROCESSOR-SDK-TDAX

Best regards,

Peter.

Please see the TIDEP-01017 User Guide

http://www.ti.com/lit/ug/tidueq8/tidueq8.pdf

Please see SW Files section on page 24.

If you have questions about the demo please start a new e2e thread so that it can be assigned to correct team

Thank you
Cesar

Hi Peter,

One path is the real-time demos provided with the Processors SDK which Cesar has linked above.

Another path is the EthernetLib which is included in the latest mmWave Studio 2.1 release. With the default install path you should find it here: C:\ti\mmwave_studio_02_01_00_00\mmWaveStudio\ReferenceCode\EthernetLib

This is the back-end API that mmWave Studio uses for communicating with the capture application running on the MMWCAS-DSP-EVM.

Thank you,

-Randy
