NeuroDataAq

Acquisition Process for Neurorobotics Project

There are three main components to this project we need to focus on:

1. Tkinter UI

This is the basic UI that should over predefined intervals expose the viewer to different arrows where the user should then respond by moving a joystick input. At the start, we'll want to use the arrow keys and once the joystick is ready, we'll be able to replace the keyboard input with joystick input.

2. Brainflow-Python Recording

python -m pip install brainflow

import argparse
import time

from brainflow.board_shim import BoardShim, BrainFlowInputParams, BoardIds, BrainFlowPresets


def main():
    BoardShim.enable_dev_board_logger()

    parser = argparse.ArgumentParser()
    # use docs to check which parameters are required for specific board, e.g. for Cyton - set serial port
    parser.add_argument('--timeout', type=int, help='timeout for device discovery or connection', required=False,
                        default=0)
    parser.add_argument('--ip-port', type=int, help='ip port', required=False, default=0)
    parser.add_argument('--ip-protocol', type=int, help='ip protocol, check IpProtocolType enum', required=False,
                        default=0)
    parser.add_argument('--ip-address', type=str, help='ip address', required=False, default='')
    parser.add_argument('--serial-port', type=str, help='serial port', required=False, default='')
    parser.add_argument('--mac-address', type=str, help='mac address', required=False, default='')
    parser.add_argument('--other-info', type=str, help='other info', required=False, default='')
    parser.add_argument('--serial-number', type=str, help='serial number', required=False, default='')
    parser.add_argument('--board-id', type=int, help='board id, check docs to get a list of supported boards',
                        required=True)
    parser.add_argument('--file', type=str, help='file', required=False, default='')
    parser.add_argument('--master-board', type=int, help='master board id for streaming and playback boards',
                        required=False, default=BoardIds.NO_BOARD)
    args = parser.parse_args()

    params = BrainFlowInputParams()
    params.ip_port = args.ip_port
    params.serial_port = args.serial_port
    params.mac_address = args.mac_address
    params.other_info = args.other_info
    params.serial_number = args.serial_number
    params.ip_address = args.ip_address
    params.ip_protocol = args.ip_protocol
    params.timeout = args.timeout
    params.file = args.file
    params.master_board = args.master_board

    board = BoardShim(args.board_id, params)
    board.prepare_session()
    board.start_stream ()
    time.sleep(10)
    # data = board.get_current_board_data (256) # get latest 256 packages or less, doesnt remove them from internal buffer
    data = board.get_board_data()  # get all data and remove it from internal buffer
    board.stop_stream()
    board.release_session()

    print(data)


if __name__ == "__main__":
    main()

3. Joystick Control

The joystick should use Ardunio which connects to a joystick and then sends the input into our Python application.
