With BrainBay IBVA interface IBVA hardware and brain-duino runs on Windows computer.

BrainBay IBVA interface was developed by Chris Veigl. Jan 2011.

http://www.shifz.org/brainbay/

Work with Windows XP, Vista, 7 and 8

This version is based on BrainBay V1.9

BrainBay V1.9 is included IBVA interface.

IBVA V5 DVD has sample configure files also.

BrainBay is open source application.

no guaranty for update and no user support.

With BrainBay IBVA interface, IBVA and brain-duino can use for experimental purpose use with Windows computer.

1:

need to download all BrainBay package from

http://www.shifz.org/brainbay/

2:

following download has more example configure files.

BrainBay IBVA interface with Configure-IBVA files : BrainBay IBVA for Windows.zip : 684 KB

3: Bluetooth setup of IBVA for Windows computer.

first need to setup Bluetooth connection in the Windows Bluetooth Device setup.

“BlueVAS_H” is name of device. Need to make power ON IBVA unit.

brain-duino may has different Bluetooth name.

“0000” is pass key.

then set COM Port name for this Bluetooth Device.

for example set COM 3.

4: In the BrainBay, Insert Source / Biosignal-Amplifier / IBVA  : “Device Protocol”

Then we can get IBVA interface “EEG” element in the Design window.

Select Comport name “COM3” this example.

set Baud Rate to 230400.

Then Click “Connect / Disconnect Com-Port”

In case works ok then “connected” will be checked.

Default Sampling Rate : 256 Hz.

Click “Display Battery Level” show Battery Voltage in the IBVA hardware.

Also can change “Set CutOff Frequency” number. Default is 0.33.

This number can setup between 0.1 to 1.0.

ex : when 256 Hz sampling

256 Hz X 0.33 = 84.48 Hz cutoff at -3 db.

use with brain-duino, high cut frequency is 30 Hz and/or 200 Hz. and need to modify Arduino code to sampling frequency 256 Hz.

Arduino Code:

https://github.com/openbrainhacking/brain-duinoV0.1/blob/master/char6BSLED1_analogIN_4chBrain_intwithClock_UNO_Bluetooth_2.ino

““char6BSLED1_analogIN_4chBrain_intwithClock_UNO_Bluetooth_2.ino” is Arduino code for use Arduino AD input. can use for 2 ch mode and 4 ch mode. 512 Hz sampling. change to 256 Hz sampling need to set Line 209 to comment and use Line 208 : de-comment”
