Synopsis

An ADC module for the Enobio Sensor developed by Neuroelectrics. ENOBIO is a wearable, modular and wireless electrophysiology sensor system for capture of

  • EEG (Electroencephalogram - brain activity)
  • ECG (Electrocardiogram - heart activity) and
  • EOG (Electrooculogram - eye movement)

  • Broken since: --

Installation

Copy:

  • ENOBIO3G.exe
  • ENOBIO3GAPI.dll
  • QtCore4.dll
  • WinBluetoothAPI.dll

to the prog directory.

Parameters

SourceCh

Indicates the number of Enobio channels to be acquired. Maximum value is 8.

SampleBlockSize

Number of samples transmitted at a time. SampleBlockSize is 30 by default.

SamplingRate

Number of samples per second recorded for each channel. Fixed value to 500.

SourceChOffset, SourceChGain

A SourceChOffset of 0, and a SourceChGain of 0.001 converts A/D units to microVolts.

ChannelNames

list of channel names

BluetoothMac

Enobio device Bluetooth MAC address 00:07:80:XX:XX:XX (look at the back of your Enobio device to get yours)

EEGChList

List of physical channel indices of the EEG channels in use.

TriggerChList

List of one-bit trigger channels to append to the end or a single 0 to acquire all trigger channels as a single 16-bit channel.

NotchFilter

Filter to remove the influence of the power line noise. Set to 50Hz in Europe or 60Hz in America.

HighPassFilter

Filter to remove the signal drift and/or low frequencies influence.

LowPassFilter

Filter to remove high frequencies influence.

AllignChannels

Bit indicating if channels shall be aligned in time. As default set as true (1).

SourceChTimeOffset

Fixed delay of the incoming signal. Empty as default.

TransmitChList

List of the channels to take part in the preprocessing stage.

Old Enobio Generation

BCI 2000 also supports old generation Enobio. A wearable, modular and wireless 4 channels electrophysiology for measuring EEG, ECG and EOG.

Installation

Copy:

  • ENOBIO.exe
  • EnobioDLL.dll

to the prog directory.

Parameters

SourceCh :Indicates the number of Enobio channels. Fixed value to 4.
SampleBlockSize: Number of samples transmitted at a time. SampleBlockSize is 25 by default.
SamplingRate: Number of samples per second recorded for each channel. Fixed value to 250.
SourceChOffset, SourceChGain: A SourceChOffset of 0, and a SourceChGain of 0.058 converts A/D units to microVolts.

Compiling Old Enobio Version

To compile old Enobio generation it is necessary to edit the CMakeLists.txt file located in http://www.bci2000.org/svn/trunk/src/contrib/SignalSource/Enobio
It is necessary to comment the line ADD_SUBDIRECTORY( Enobio3G ) and uncomment ADD_SUBDIRECTORY( Enobio )
