Library for interfacing with Neurosky's Mindwave EEG headset
NeuroSkyPy library written in python3.7 to connect, interact, get, save and plot data from NeuroSky's MindWave EEG headset, the first one ( black ).
This library is based on the mindwave mindset communication protocol published by Neurosky and is tested with Neurosky Mindwave EEG headset. Where It's readen the data in hex, after that it's decoded.
- Download the source file from github
- Unzip and navigate to the folder containing
setup.pyand other files
- Run the following command:
python setup.py install
pip3 install NeuroSkyPy
A test-script which is used as experiment it's left in order to check and learn how to use the class. The basic steps to use the class are:
- Importing the module:
from NeuroPy import NeuroPy
neuropy = NeuroPy()
- After initializing, either the callbacks can be set or just extract data from the object as it's done in test-script.
- Then call
neuropy.start()method, it will start fetching data from mindwave.
- To stop call
neuropy.stop()WARNING: The main problem it's that the thread is not stopped so it will trigger a error. Nevermind you could continue using the script.
Obtaining Data from Device
attention = neuropy.attention#to get value of attention_
Other Variable 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:
for eg. to set a callback for attention data the syntax will be
Other Variables: attention, meditation, rawValue, delta, theta, lowAlpha, highAlpha, lowBeta, highBeta, lowGamma, midGamma, poorSignal and blinkStrength
Sample Program 1 (Access via callback)
from NeuroPy import NeuroPy from time import sleep neuropy = NeuroPy() 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) return None neuropy.setCallBack("attention", attention_callback) neuropy.start() try: while True: sleep(0.2) finally: neuropy.stop()
Sample Program 2 (Access via object)
from NeuroPy import NeuroPy from time import sleep neuropy = NeuroPy() neuropy.start() while True: if neuropy.meditation > 70: # Access data through object neuropy.stop() sleep(0.2) # Don't eat the CPU cycles
