EventExchanger

Disclaimer:

C-Sharp code to communicate with the hardware the University of Groningen, faculty of Behaviour and Social Sciences, department of Research Support developed.

Code Written by Eise Hoekstra and Mark M. Span, Maintained by Mark M. Span

Usage:

Any environment that can read and use .net code will be able to use this library.

e.g., Matlab and Python.

For Python: Preferred use:

Wrapper library: pyEVT

https://github.com/markspan/pyEVT

Manual use:

 pip install pythonnet

and then things like this:

import clr
clr.AddReference("System.Reflection")
from System.Reflection import Assembly
            
directory = os.path.dirname(__file__)
Assembly.UnsafeLoadFrom(directory+'\HidSharp.dll')
Assembly.UnsafeLoadFrom(directory+'\HidSharp.DeviceHelpers.dll')
Assembly.UnsafeLoadFrom(directory+'\EventExchanger.dll')
            
EVT2 = clr.ID.EventExchanger()
EVT2.Start()

after wich you can:

EVT2.PulseLines(code,ms)

For Matlab:

% Put the three (3) dll's in the current directory for the task!
warning ('off', 'MATLAB:NET:AddAssembly:nameConflict');
NET.addAssembly([pwd '\EventExchanger.dll']);
warning ('on', 'MATLAB:NET:AddAssembly:nameConflict');
 
% the needed dll are:
% EventExchanger.dll,
% HidSharp.dll and
% HidSharp.DeviceHelpers.dll
 
% Create and start the object
EE = ID.EventExchanger;
EE.Start();
 
% if multiple EVT-2s are connected add a serialnumber as parameter to start
% e.g.,
% EE.Start('11007');

% to pulse the port with number x for y millisecs do:
% EE.PulseLines(x,y);
 
EE.PulseLines(255,4);
 
% Thank you, come again!
