AWR1642BOOST: Collecting Raw ADC Data using MATLAB

Hi Jitendra,

Thanks for your reply.

I just invoked the following command on octave command line after RSTD.NetStart() has been executed on mmwave studio lua shell and saw the following error:

octave:3> RSTD_Interface_Example
Adding RSTD Assembly
error: 'NET' undefined near line 9 column 21
error: called from
   Init_RSTD_Connection at line 9 column 19
   RSTD_Interface_Example at line 6 column 11
octave:3>

It seems like i have encountered the error at NET in the script. RSTD_Interface_Example.m looks like this:

function ErrStatus = Init_RSTD_Connection(RSTD_DLL_Path)
%This script establishes the connection with Radarstudio software
%   Pre-requisites:
%   Type RSTD.NetStart() in Radarstudio Luashell before running the script. This would open port 2777
%   Returns 30000 if no error.

if (strcmp(which('RtttNetClientAPI.RtttNetClient.IsConnected'),'')) %First time the code is run after opening MATLAB
    disp('Adding RSTD Assembly');
    RSTD_Assembly = NET.addAssembly(RSTD_DLL_Path);
    if ~strcmp(RSTD_Assembly.Classes{1},'RtttNetClientAPI.RtttClient')
        disp('RSTD Assembly not loaded correctly. Check DLL path');
        ErrStatus = -10;
        return
    end
    Init_RSTD_Connection = 1;
elseif ~RtttNetClientAPI.RtttNetClient.IsConnected() %Not the first time but port is diconnected
    % Reason:
    % Init will reset the value of Isconnected. Hence Isconnected should be checked before Init
    % However, Isconnected returns null for the 1st time after opening MATLAB (since init was never called before)
    Init_RSTD_Connection = 1;
else
    Init_RSTD_Connection = 0;
end
if Init_RSTD_Connection
    disp('Initializing RSTD client');
    ErrStatus = RtttNetClientAPI.RtttNetClient.Init();
    if (ErrStatus ~= 0)
        disp('Unable to initialize NetClient DLL');
        return;
    end
    disp('Connecting to RSTD client');
    ErrStatus = RtttNetClientAPI.RtttNetClient.Connect('127.0.0.1',2777);
    if (ErrStatus ~= 0)
        disp('Unable to connect to Radarstudio');
        disp('Reopen port in Radarstudio. Type RSTD.NetClose() followed by RSTD.NetStart()')
        return;
    end
    pause(1);%Wait for 1sec. NOT a MUST have.
end
disp('Sending test message to RSTD');
Lua_String = 'WriteToLog("Running script from MATLAB\n", "green")';
ErrStatus = RtttNetClientAPI.RtttNetClient.SendCommand(Lua_String);
if (ErrStatus ~= 30000)
    disp('Radarstudio Connection Failed');
end
disp('Test message success');
end

Can you suggest ? Please note windows 10 (64bit) is running on my PC and it supports .NET Framework 4.7.2.

Hi,

I`m still getting stuck at the following error on octave :

octave:3> RSTD_Interface_Example
Adding RSTD Assembly
error: 'NET' undefined near line 9 column 21
error: called from
   Init_RSTD_Connection at line 9 column 19
   RSTD_Interface_Example at line 6 column 11
octave:3>

Could you please suggest ?

NK,

Here is a small example script that you can run in mmWave studio, we will also run the same commands in MatLab, just make sure that you are able to run these in mmWave studio.

1. Create a text file.
2. Copy and paste the lua code below.
3. Modify your location for the BSS and MSS firmware files.
4. save it with a “.lua” extension
5. Run the script from mmwave studio according to the instruction on “Automation/Scripting” in the "mmwave_studio_user_guide.pdf"

-- ************** Lua Code Begins*******************

-- Reset control
ar1.SOPControl(2)

--RS232 connection
ar1.Connect(6,921600,1000)

-- Files
ar1.DownloadBSSFw("C:\\ti\\mmwave_studio_<version>\\rf_eval_firmware\\radarss\\xwr16xx_radarss.bin")
ar1.DownloadMSSFw("C:\\ti\\mmwave_studio_<version>\\rf_eval_firmware\\masterss\\xwr16xx_masterss.bin")

-- SPI operations
ar1.PowerOn(0, 1000, 0, 0)
ar1.RfEnable()

-- ******************** end Lua code ********************

Following the instruction and sample code in the "mmwave_studio_user_guide.pdf" , in the chapter named "Controlling mmWaveStudio from Matlab"
create the scripts "RSTD_Interface_Example.m" and "Init_RSTD_Connection.m".

After you have ran the scripts "RSTD_Interface_Example.m" and "Init_RSTD_Connection.m", then you can begin passing all the above commands as MatLab strings, examples below.

% Matlab Code begins

RtttNetClientAPI.RtttNetClient.SendCommand("ar1.SOPControl(2)");

RtttNetClientAPI.RtttNetClient.SendCommand("ar1.Connect(6,921600,1000)");

RtttNetClientAPI.RtttNetClient.SendCommand("ar1.DownloadBSSFw("C:\\ti\\mmwave_studio_<version>\\rf_eval_firmware\\radarss\\xwr16xx_radarss.bin")");

RtttNetClientAPI.RtttNetClient.SendCommand("ar1.DownloadMSSFw("C:\\ti\\mmwave_studio_<version>\\rf_eval_firmware\\masterss\\xwr16xx_masterss.bin")");

RtttNetClientAPI.RtttNetClient.SendCommand("ar1.PowerOn(0, 1000, 0, 0)");

RtttNetClientAPI.RtttNetClient.SendCommand("ar1.RfEnable()");

% MatLab code ends

Hope this was helpful.

Hi Alex,

Thank you for your help. Last Week, I had been able to capture raw data in matlab by initiating lua scripts from there. But still, the above example you provided would be helpful for other users.

OK, another problem is still pending. Please note i`m using free evaluation version of matlab and it would be expired in 1 month. So If you have any trick to use .NET from free matlab-like tool, say octave, please let me know.

Best Regards,
NK
