DCA1000EVM: DCA1000EVM+IWR1443BOOST without mmWave Studio ?

Part Number: DCA1000EVM
Other Parts Discussed in Thread: IWR1443BOOST, IWR1443

Hi, I'm running the mmWave Studio (1.0.0.0) demo with DCA1000EVM and IWR1443BOOST radar board.

The demo is working fine on my laptop with default LUA script (DataCaptureDemo_xWR.lua).

However, it seems that the demo mode is quite slow and cannot be easily automated... (but maybe I'm wrong ?).

My question is: is it possible to capture raw data with the DCA1000EVM with a standalone software (without using mmWave Studio) ?

Based on the DCA1000 user guide (http://www.ti.com/lit/pdf/spruij4),

I wrote a piece of C code and I'm able to send command over the UDP link (port 4096) to start and stop the capture and I'm also able to read the data flow on port 4098 to do real time processing.

However, I still need mmWave Studio to perform the initial configuration phase (SPI connect and LUA script commands like ar1.PowerOn, ar1.RfEnable... ar1.ChirpConfig... ar1.StartFrame...).

I did not find any information in the documents about the commands to send on the COM ports.

What is the action of ar1.PowerOn, at1.RfEnable... macros ?

It would be nice if this part of the interface is also documented in order to write my own software, because I would like to automate the capture without handling the mmWave Studio GUI.

Thanks for your help

    Oliver,

    Q1 ) The demo mode is quite slow and cannot be easily automated... (but maybe I'm wrong ?).
    R1 ) How fast do you need mmWave to be? what are you trying to do? once the device is set up its faster to just make multiple captures.

    Q2 ) is it possible to capture raw data with the DCA1000EVM with a standalone software (without using mmWave Studio) ?
    R2 ) Unfortunately, the set up at this time cannot.

    Thanks for your answer.
    mmWave Studio is fast enough to run one capture, but the initial setup, including FW reflash, is quite long.
    For repeated captures, it would be nice to have access to the IWR1443 firmware source code like for other demos, as well as to the protocol specification between mmWave Studio and the IWR1443BOOST board in order to increase learning speed.

    Oliver,

    Unfortunately there is currently no way of doing what you want without mmWave Studio.
