About connection of Neurosky Mindwave

Unity Engine

Hi guys, I’m a beginner of Unity,doing a project with Unity and Neurosky Mindwave, and have some problem with the connection of EEG(EEG has connected with the computer, but it can’t connect with Unity). I’ve downloaded a project from Neurosky website, but it seems not working.
It shows:
Failed to load ‘Assets/Plugins/ThinkGear.dll’, expected 64 bit architecture (IMAGE_FILE_MACHINE_AMD64), but was IMAGE_FILE_MACHINE_I386. You must recompile your plugin for 64 bit architecture.
UnityEngine.Component:SendMessage(String)

The script is:
enum AppState {
Disconnected = 0,
Connecting,
Connected
}

var portName : String;

private var showErrorWindow : boolean = false;
private var showConnectedWindow : boolean = false;
private var showDisconnectedWindow : boolean = false;
private var state : AppState = AppState.Disconnected;
private var headsetValues : Hashtable;
private var windowRect : Rect = new Rect(100, 100, 150, 100);

function OnGUI(){
GUILayout.BeginHorizontal();

switch(state){
case AppState.Disconnected:
// display UI for the user to enter in the port name and connect
GUILayout.Label(“Port name:”);
portName = GUILayout.TextField(portName, GUILayout.Width(150));

if(GUILayout.Button(“Connect”)){
state = AppState.Connecting;
SendMessage(“OnHeadsetConnectionRequest”, portName);
}

break;

case AppState.Connecting:
GUILayout.Label(“Connecting…”);
break;

case AppState.Connected:
// display UI to allow a user to disconnect
GUILayout.Label(“Connected”);

if(GUILayout.Button(“Disconnect”))
SendMessage(“OnHeadsetDisconnectionRequest”);

break;
}

GUILayout.EndHorizontal();

// only output the headset data if the headset is
// connected and transmitting data
if(state == AppState.Connected && headsetValues){
for(var key : String in headsetValues.Keys){
var value : float = headsetValues[key];
GUILayout.Label(key + ": " + value);
}
}

if(showErrorWindow)
GUILayout.Window(0, windowRect, ErrorWindow, “Error”);

if(showConnectedWindow)
GUILayout.Window(0, windowRect, ConnectedWindow, “Connected”);

if(showDisconnectedWindow)
GUILayout.Window(0, windowRect, DisconnectedWindow, “Disconnected”);
}

/*

  • Event listeners
    */

function OnHeadsetConnected(){
showConnectedWindow = true;
state = AppState.Connected;
}

function OnHeadsetConnectionError(){
showErrorWindow = true;
state = AppState.Disconnected;
}

function OnHeadsetDisconnected(){
showDisconnectedWindow = true;
state = AppState.Disconnected;
}

function OnHeadsetDataReceived(values : Hashtable){
headsetValues = values;
}

/**

  • Disconnect the headset when the application quits.
    */
    function OnApplicationQuit(){
    SendMessage(“OnHeadsetDisconnectionRequest”);
    }

/*

  • Status windows
    */

function ErrorWindow(){
GUILayout.Label(“There was a connection error.”);
if(GUILayout.Button(“Close”))
showErrorWindow = false;
}

function ConnectedWindow(){
GUILayout.Label(“The headset has been successfully connected.”);

if(GUILayout.Button(“Okay”))
showConnectedWindow = false;
}

function DisconnectedWindow(){
GUILayout.Label(“The headset has been disconnected.”);

if(GUILayout.Button(“Okay”))
showDisconnectedWindow = false;
}

Does any know how to fix it? Thanks.

Looks like architecture error, your system its 64bits and the .dll files are x86. Did you downloaded the assets provided from neurosky webpage?

I’m also start now to work with neurosky and unity.
Have you succeed?
