#Overview

Emoren reads EEG data from the EPOC+ headset. It is based on emokit. It differs from emokit by using python3 instead of python2, replaces Crypto with cryptography, and do not use gevents. To visualize the EEG data, numpy and matplotlib is required.

The script requires pyhidapi, which in turn requires hidapi.

#Install prerequisites

The scripts have been tested on MacOS X and with Ubuntu, with both python2 and python3.

###Mac hidapi installation

brew install hidapi

###Linux hidapi installation:

sudo apt-get install libudev-dev libusb-1.0-0-dev autotools-dev autoconf automake libtool
git clone https://github.com/signal11/hidapi
cd hidapi
./bootstrap
./configure
make
sudo make install
cd ..

To make sure that the hidraw devices are readable, follow these instructions, a working config line might look like

SUBSYSTEM=="hidraw", ATTRS{idVendor}=="1234", ATTRS{idProduct}=="ed02", MODE="0666"

Make sure the idVendor and idProduct matches your device, you can list usb devices with lsusb.

##All:

pip install cryptography    <--- make sure you have libssl-dev and libffi-dev on linux

git clone https://github.com/NF6X/pyhidapi.git
cd pyhidapi
# Under linux, to make sure you use the hidraw devices first, you might have to swap line 157 and 158 in hidapi/hidapi.py before installing
python setup.py install
cd ..

#Usage

Now if you run python emoren.py you should see that packets are received.

For plotting and saving binary dumps:

pip install numpy
pip install matplotlib

# Capture data and visualize by running
python plot.py
