2. Processing getting the signal through Arduino and trying to match all predefined conditions, After one of the function is being triggered then send the request back to Arduino.

features, to select those via user.py and... to trigger several plugins at the same time. See code and README (or even logs to see how trivial it is to convert current code to plugins), I think it's

I want to use a range of  emotional responses to trigger certain visual and auditory events, and I know from working with NeuroSky that can be accomplished with meditation and focus. So now that I can

int trigger = 18;

Marksmen consistently showed an increase in alpha power (seen in all electrode sites) beginning approximately two seconds before trigger pull, and a modest increase in theta power (seen only in right

The LabStreamingLayer driver is a great addition and will help in synchronizing various trigger signals and such.

Maybe a better way to use multiple boards simultaneously is to use an external trigger, or have one board trigger the other(s) as a way to sync the data streams...

It's possible to dedicate one of the ADS1299 inputs to record a trigger event.More useful is to use one of the broken out pins of the ATmega or PIC.

Trigger is just only time stamp that let me know where is the starting point of each stimulation onset.

You didnt answer my question earlier. What is the trigger info coming in on UDP?  Does it HAVE to be UDP.  Heck ethernet or wireless delays could impact you if you are that time constrained.

However, it's better to send the trigger signal from visual stimulation itself without any additional wire or sensor. (As Chip's blog, he used photo sensor for recording flickering frequency of his vi

I was also curious about your statement that you were only using 1 channel of EEG.  Is that really enough to do a P300 speller?  :-)  What is the trigger that sends your UDP message?  Can't you just u

The red line show examples of time stamps of trigger data based on UDP events. 

  incomingMouseX = theOscMessage.get(idxtrigger).intValue();

happen, and then start new thread for recording trigger data on another .txt file.

I modified OpenBCI_GUI. I tried to recorded trigger data from another Processing sketch. 

visual stimulation to recording program, and trigger data from visual stimulation program is important > testing in online mode is my ultimate goal

BCI hacks, I've used these Alpha rhythms to trigger lights and to control robots.  I figured that I'd explore in a little more detail different refinements on algorithms to get solid Alpha detection.

The Bioexplorer and Bioera biofeedback / neurofeedback applications are easily used to produce MIDI output from EEG. One of the modules is a MIDI sound device. It can take trigger inputs from Thresh
