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](http:://neurosky.com) and is tested
with Neurosky Mindwave EEG headset.
##Installation##
1. Download the source distribution (zip file) from [dist directory](https://github.com/lihas/NeuroPy/tree/master/dist)
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_ <br /> `object1=NeuroPy("/dev/rfcomm0",57600)` _#linux_
Note: Add a True argument to emit the magic hex sequence for a MindFlex toy set up to run at 57600 baud
using the hack described here: http://www.instructables.com/id/Mindflex-EEG-with-raw-data-over-Bluetooth/
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)` <br />
__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
