Hello Raha
I understand that you are trying to connect a Thorlabs LTS150 to MATLAB using .NET functions but you are unable to establish the connection.
You can use the complete name of the module you want to use, i.e. ‘Thorlabs.MotionControl.IntegratedStepperMotorsCLI.LongTravelStage’, to call its functions. Please refer to the following code snippet:
clc;
clear all;
%Set up paths of the dll files required
MOTORPATHDEFAULT = 'C:\Program Files\Thorlabs\Kinesis\';
DEVICEMANAGERDLL= 'Thorlabs.MotionControl.DeviceManagerCLI.dll';
GENERICMOTORDLL= 'Thorlabs.MotionControl.GenericMotorCLI.dll';
INTSTEPPERMOTORDLL= 'Thorlabs.MotionControl.IntegratedStepperMotorsCLI.dll';
%Load .dll files associated with the Thorlabs motor
asm_dev = NET.addAssembly([MOTORPATHDEFAULT, DEVICEMANAGERDLL]);
asm_gen = NET.addAssembly([MOTORPATHDEFAULT, GENERICMOTORDLL]);
asmInfo = NET.addAssembly([MOTORPATHDEFAULT, INTSTEPPERMOTORDLL]);
% Generate device list
Thorlabs.MotionControl.DeviceManagerCLI.DeviceManagerCLI.BuildDeviceList(); % Build device list
serialNumbers =Thorlabs.MotionControl.DeviceManagerCLI.DeviceManagerCLI.GetDeviceList(); % Get device list
serialNumbers = cell(ToArray(serialNumbers)); % Convert serial numbers to cell array
if isempty(serialNumbers)
short_warn('No Thorlabs stages found!');
return;
end
defaultSerialNr = '45357364'; % Correct Serial Number
deviceFound = any(strcmp(serialNumbers,defaultSerialNr)); %Try to check if the device is found
if deviceFound
DeviceNet = Thorlabs.MotionControl.IntegratedStepperMotorsCLI.LongTravelStage.CreateLongTravelStage(defaultSerialNr); %Create the .NET object
fprintf('Device found...');
else
short_warn('Device not found!');
fprintf('Devices available:\n');
fprintf('%s\n',serialNumbers{:});
fprintf('Expected: \n');
fprintf('%s\n',defaultSerialNr);
return;
end
fprintf('connecting...');
DeviceNet.ClearDeviceExceptions();
% Clears the the last device exceptions if any.
DeviceNet.ConnectDevice(defaultSerialNr);
DeviceNet.Connect(defaultSerialNr);
% Connects to the device with the supplied serial number.
For further understanding, you can also refer to ‘Thorlabs.MotionControl.DotNet_API.chm’ at ‘C:\Program Files\Thorlabs\Kinesis’
I hope this helps!
Best Regards
Garmit
