Tutorial 1 Braintone - AtlantsEmbedded/IntelliPi GitHub Wiki

Requirements

Prior to this tutorial, make sure you have:

completed the Complete Guide to Getting Started.
a USB 2.0 Bluetooth dongle (specifically CSR)
a MUSE eeg headband
a Piezo buzzer and two wires <@diagram to come>

IntelliPi configuration

Make sure to select the following packages in the menuconfig (some are there by default, but better be sure):

Atlants->Application->braintone_app
Atlants->Interface->DATA_interface
Atlants->preprocessing->DATA_preprocessing
Atlants-GPL->librairies->wiringPi
Librairies->bluez-libs
Utilities->bluez-utils

You can now build the image and dd it to an SD card, by following the instructions in the Getting Started Section.

Hardware configuration

Before powering up the Raspberry Pi, make sure to attach the piezo-buzzer to GPIO 1 (wiringPI convention). The correct way to connect it is indicated in the following schematic:

Application configuration

You can now power up the Raspberry Pi and SSH to it, by following the instructions in the Getting Started.

You then need to find the MAC address of your Muse. To do this, power up the Muse and scan using the following command:

$hcitool scan

Take note of the MAC address and copy it - using the vi text editor - in the config file of the DATA_interface located:

/intelli/data/config/data_config.xml

Copy within the remote_addr xml tags

Launching the application

You can start Braintone by calling the script this way:

$./intelli/launch_braintone.sh start

During execution, you can stop it by typing:

$./intelli/launch_braintone.sh stop

The best way to achieve this is to tap arrow up, backspace 3 times and write the letter "op"
