Tool/software: Code Composer Studio
Hi all,
I'm using AWR1642BOOST ES1.0 / DCA1000EVM / window 7 64 bit machine / mmWave studio2.0
currently I can output the raw data and postproc it with mmWave studio and see the MATLAB plot result of 1D FFT/2DFFT and angle estimation
However, I wonder if I can output the data after Range FFT / Doppler FFT / Azimuth FFT instead of the raw data after adc sampling with DCA1000EVM
I wish to analyze the results after those FFTs
Is there anyway I can do this with my DCA1000EVM?
Best Regards
Brian.
Hello, Jitendra
so I am able to output the user data through LVDS to DCA1000 and then through ethernet to my PC right?
but in the link below the answer is NO, I wonder is there a difference between our problems?
And if I am able to do so, can you tell me more in detail that how should I output my user data?
for example the demo code in mmwave_automotive_toolbox_1_2_0\labs\lab0002_short_range_radar
where should I edit the code to output the data of the result of 1D FFT to my PC?
Thanks alot for your help
Hi, Jitendra
Thanks for your reply, I will try to figure out how these command works in both SDK and SRR demo code
So I don't need mmwave studio while I want to output those results of FFTs through LVDS to DCA1000EVM and then ethernet to PC right?
Then how should I command the DCA1000 like dumping the file at a specified path on my PC or saving the data in specific format?
Are there Libraries or functions to control DCA1000?
Best Regards
Brian.
Hello Brian,
For any kind of data streaming over LVDS from device using DCA1000 you need to connect this EVM to PC over ethernet.
Currently we provide only mmWave-Studio as a solution to control/capture DCA1000EVM, where if you are trying to capture any data with embed application running on AWR1642 then mmWave-Studio provides few LUA functions which you need to run in mmWave-Studio LUA shell window. Here is the code snippet which you need to run in the LUA shell-
-- To get the API description use help command in the same shell, as 'help ar1.SelectCaptureDevice' -- select Device type if (ar1.SelectCaptureDevice("DCA1000") == 0) then WriteToLog("SelectCaptureDevice Success\n", "green") else WriteToLog("SelectCaptureDevice failure\n", "red") end RSTD.Sleep(1000) --DATA CAPTURE CARD API if (ar1.CaptureCardConfig_EthInit_WithoutSPI("192.168.33.30", "192.168.33.180", "12:34:56:78:90:12", 4096, 4098) == 0) then WriteToLog("CaptureCardConfig_EthInit Success\n", "green") else WriteToLog("CaptureCardConfig_EthInit failure\n", "red") end RSTD.Sleep(1000) --AR12xx or AR14xx-1, AR16xx- 2 (second parameter indicates the device type) if (ar1.CaptureCardConfig_Mode_WithoutSPI(1, 2, 1, 2, 3, 30) == 0) then WriteToLog("CaptureCardConfig_Mode Success\n", "green") else WriteToLog("CaptureCardConfig_Mode failure\n", "red") end RSTD.Sleep(1000) if (ar1.CaptureCardConfig_PacketDelay_WithoutSPI(25) == 0) then WriteToLog("CaptureCardConfig_PacketDelay Success\n", "green") else WriteToLog("CaptureCardConfig_PacketDelay failure\n", "red") end RSTD.Sleep(1000) --Capture Card FPGA ar1.GetCaptureCardFPGAVersion_WithoutSPI() RSTD.Sleep(1000) --Capture Card DLL ar1.GetCaptureCardDllVersion_WithoutSPI() RSTD.Sleep(1000) --Start Record ADC data [change this path as required] ar1.CaptureCardConfig_StartRecord("d:\mmwave_lvds_data.bin", 1) RSTD.Sleep(1000) --Stop Record ADC data ar1.CaptureCardConfig_StopRecord_WithoutSPI() RSTD.Sleep(1000) --Disconnect API ar1.CaptureCard_DisConnect_WithoutSPI() RSTD.Sleep(1000)
In other case you don't want to use mmWave-Studio then you need to write your own tool to control/capture DCA1000EVM, code reference is provided in
C:\ti\mmwave_studio_02_00_00_02\mmWaveStudio\Clients\AR1xController\rf_api.h where all dca1000 APIs are available in RF_API.dll
Captured data format will be the same as the embedded application is sending from the device, enable the HSI header which you can easily search in the captured file to get the marker.

Hi, Jitendra
So if I'm not getting it wrong
Having a edited code bin flashed in my EVM, I can output the user data through LVDS to DCA1000EVM while the Radar is functioning
And then through mmWave studio's lua script I can control DCA1000EVM to output the user data to my PC
thanks a lot for your help
Best regards,
Brian
