========================= explorepy overview

explorepy is an open-source Python API designed to collect and process ExG data using Mentalab's Explore device. Amongst other things, explorepy provides the following features:

• Real-time streaming of ExG, orientation and environmental data.
• Real-time visualization of ExG, orientation and environmental data.
• Data recording in CSV and BDF+ formats.
• Integration with LabStreaming Layer.
• Electrode impedance measurements.
• Explore device configuration.

Quick installation

For Windows users, the best way to install explorepy is to download the latest explorepy version from the release page <https://github.com/Mentalab-hub/explorepy/releases>_. Please note that dependencies will install automatically from the release page.

For other operating systems, or to build the package manually on Windows, please refer to the information below.

Requirements

• Python 3.6 to Python 3.9.
• Visual Studio 2015 community edition (Windows only. For package building).
• Bluetooth header files (Linux only. Use: sudo apt-get install libbluetooth-dev).

Detailed installation instructions can be found on the installation page <https://explorepy.readthedocs.io/en/latest/installation.html>_.

To install explorepy from PyPI run: ::

pip install explorepy

To install the latest development version (git must be installed before running this command): ::

pip install git+https://github.com/Mentalab-hub/explorepy

Get started

CLI command

To check explorepy is running use: :: explorepy acquire -n Explore_XXXX

For help, use: :: explorepy -h

Python code

In Python you can connect to the Explore device and print data using:

::

import explorepy
explorer = explorepy.Explore()
explorer.connect(device_name="Explore_XXXX")  # Put your device Bluetooth name
explorer.acquire()

You can also visualize the data in real-time.

::

import explorepy
explorer = explorepy.Explore()
explorer.connect(device_name="Explore_XXXX")  # Put your device Bluetooth name
explorer.visualize(bp_freq=(.5, 30), notch_freq=50)
