openbci-archive / _deprecated_openbci-v2hardware

This repository contains the core OpenBCI hardware and software frameworks.

WELCOME!

Welcome to OpenBCI's Github. This is the place where we will keep the software that we want to share with the community and where we will keep the software that the community shares with us.

Contents

• Arduino: Here are the Arduino libraries and sketches to help you run OpenBCI with an Arduino. Currently, all development has been with the Arduino UNO. We will expand to other Arduino platforms in the future.

• Processing GUI: Here are some Processing libraries and sketches to help you receive data from the Arduino/OpenBCI. You can use these sketches to watch the data in real time. Some of the sketches also log the data to disk so that you can analyze it after the test.

_deprecated_openbci-v2hardware's Issues

Python GUI connection sequence incompatible with 32bit board

The python code never tries to write 'v' to the serial device during the connection sequence. After including a this in the EEGSensor.connect() function, a connection is made but a RuntimeError is thrown:

RuntimeError: Maximum number of bytes skipped looking for binary packet (3000)

This occurs after the program warns:

Had to skip N bytes before finding stop/start bytes
Message length is the wrong size! X should be Y.

Has anyone had success with the Python_GUI code using the 32bit board?

Headware missing

But I can't find the STL files in this repository.
Just software.

Error building exe of python gui

setup.py fails when trying to build an exe using either the newest Anaconda or Canopy 32bit with the newest 32bit cx_Freeze. This occurs even though run.py successfully launches the GUI from Anaconda or Canopy, indicating that all dependencies are correctly installed. Knowing which exact versions of Anaconda/cx_Freeze were used would be useful.

Cannot find anything named "sendToSpectrogram"

I am tring to run OpenBCI_GUI_Simpler code in processing 2.2.1 and I am getting a message as Cannot find anything named "sendToSpectrogram". Fairly new to this. Need help. Thank You

OpenBCI_GUI code runs just fine but I have this message when running OpenBCI_GUI_Simpler code.

error while running the file, i have attached error displayed

"Simpler" Processing GUI: Add ding/buzz when Alpha detected

My latest update to the "Simpler" Processing GUI has a routine that detects the presence of alpha waves. Would be nice if it dinged/buzzed when alpha was detected so that you could tell it was happening even when your eyes are closed.

One idea would be for it to create a steady tone (saw tooth or square wave) whenever the alpha was detected. The pitch could then increase based on the intensity (strength) of the alpha waves.

Whatever way that you/we choose to do this, don't forget to turn off the tone when the alpha is no longer detected.

Processing GUI: add buttons to insert "markers" in data log

To ease post-test analysis of the data, it would be great if we could insert "markers" into the data stream. These could be used to mark things like "eyes open", "eyes closed", "relaxed", "flexing left arm", "concentrating on mental math", etc.

One way to enter these markers would be to have clickable buttons on the GUI. Or, you could press keys on the keyboard (say, the function keys).

One could pre-define the message associated with each button ("Eyes Closed"), or one could leave them user-definable (with default messages, of course).

The markers could be stored in the existing data log (the big text file that is generated while recording EEG data). I recommend creating a second file to hold just this log data. I recommend logging a code that identifies which button/key was pressed (the code should something that is easily machine readable), followed by the EEG sample number of when the button was pressed (this acts as the clock for associating with the EEG data), and finally the text message itself.

This will be the first step in our path to enabling people to do automated test protocols so that we can share our EEG data and do some actual science. In the vision for the automated test protocol, the GUI itself could drop markers into this log file to say when the visual stimulus (or whatever) was incremented to the next step in the test protocol.

Uploading Arduino Due Libraries to Arduino Due

Hello,

I am trying to upload the arduino due libraries to my arduino due, but there is no .ino file to use. I am fairly new to this, so I would appreciate some help.

Thank you

Arduino UNO and ADS1299FE KIT (with MMB0)

I use arduino Uno and level shifter,bidirectional bus, 5V->3,3V. All these pin are with 3.3V
13 - SCLK*
12- MISO*
11-MOSI*
10- CS*
9-RESET*
8 -DRDY*
7-START*
Power Source are provided from MMB0 of the TI Kit.
I run example1, but all register are set to 1 (i add to ads.inizialize funciont the "false" argument for daisychain)
Why i cannot read correctly the register value???

Problem with UNO

I am having problems with interfacing my ads1299FE with arduino UNO. I was trying to stream data as txt using the ADSMangager but it seems i am getting some gibberish values also the registers seem to be not read properly. Could any one suggest a suitable circuit diagram for UNO and ads1299 daughter board?
