NeuroPy

NeuroPy library written in python to connect, interact and get data from neurosky's MindWave EEG headset.

This library is based on the minwave mindset communication protocol published by Neurosky and is tested with Neurosky Mindwave EEG headset.

Note: I only have MindWave mobile, and therefore this library is supposed to work on it. I do not promise if it will work on other models. Another library which was suggested to me after I wrote this library can be found HERE. I have not tested that library, and cannot give any gurantees. More about the difference between the models of MindWave can be found HERE.

Installation

1. Download the source distribution (zip file) from dist directory or from PyPi
2. unzip and navigate to the folder containing setup.py and other files
3. run the following command: python setup.py install

Usage

1. Importing the module: from NeuroPy import NeuroPy

2. Initialising: object1=NeuroPy("COM6",57600) #windows
   object1=NeuroPy("/dev/rfcomm0",57600) #linux

3. After initialising , if required the callbacks must be set then using the start method the library will start fetching data from mindwave i.e. object1.start() similarly stop method can be called to stop fetching the data i.e. object1.stop()

The data from the device can be obtained using either of the following methods or bot of them together:

• Obtaining value: variable1=object1.attention #to get value of attention

  #other variables: attention,meditation,rawValue,delta,theta,lowAlpha,highAlpha,lowBeta,highBeta,lowGamma,midGamma, poorSignal and blinkStrength

• Setting callback:a call back can be associated with all the above variables so that a function is called when the variable is updated. Syntax: setCallBack("variable",callback_function)
  for eg. to set a callback for attention data the syntax will be setCallBack("attention",callback_function)

  #other variables: attention,meditation,rawValue,delta,theta,lowAlpha,highAlpha,lowBeta,highBeta,lowGamma,midGamma, poorSignal and blinkStrength

Sample Program

from NeuroPy import NeuroPy
object1=NeuroPy("COM6") #If port not given 57600 is automatically assumed
                        #object1=NeuroPy("/dev/rfcomm0") for linux
def attention_callback(attention_value):
    "this function will be called everytime NeuroPy has a new value for attention"
    print "Value of attention is",attention_value
    #do other stuff (fire a rocket), based on the obtained value of attention_value
    #do some more stuff
    return None

#set call back:
object1.setCallBack("attention",attention_callback)

#call start method
object1.start()

while True:
    if(object1.meditation>70): #another way of accessing data provided by headset (1st being call backs)
        object1.stop()         #if meditation level reaches above 70, stop fetching data from the headset
