How do I code to grab the waveform of Lecroy oscilloscope waiting till the trigger pulse?

function waveform_read

% Create a TCPIP object.

interfaceObj = instrfind('Type', 'tcpip', 'RemoteHost', '169.254.66.12', 'RemotePort', 1861, 'Tag', '');

% Create the TCPIP object if it does not exist

% otherwise use the object that was found.

if isempty(interfaceObj)

interfaceObj = tcpip('169.254.66.12', 1861);

else

fclose(interfaceObj);

interfaceObj = interfaceObj(1);

end

set(interfaceObj,'InputBufferSize',30000);

% Create a device object.

deviceObj = icdevice('lecroy_8600a.mdd', interfaceObj);

% Connect device object to hardware.

connect(deviceObj);

% Disconnect device object from hardware.

%disconnect(deviceObj);

% Configure property value(s).

set(interfaceObj, 'Name', 'TCPIP-169.254.66.12');

% Disconnect device object from hardware.

%disconnect(deviceObj);

set(interfaceObj, 'RemoteHost', '169.254.66.12');

% Start Timer

n=2

t=0;

% Execute device object function(s).

pause(n)

a=t+1

b=10

c=mod(a,b)

groupObj = get(deviceObj, 'Waveform');

groupObj = groupObj(1);

[X,Y] = invoke(groupObj, 'readwaveform', 'channel1');

figure(1)

plot(Y,X)

I have this code which just grabs the data of my oscilloscope whatever is there on the screen, I need help to edit this one to get a infinite loop which waits for a trigger to get the waveform instead of grabbing every information on the screen. I want to store the trigger time, and the maximum phase value of the waveform obtained at each time of trigger. I want the data for 10s, so the time should be mod time ( ex: if time is 11 its mod value is 1, for 22 its 2). I want each maximum values updated denoting the points on the phase graph. and waveform at each trigger time. Please help.

Could you share if you found a solution for instantaneous acquiring of signal with trigger event? it will be really helpful for me.
