    openbci-rx

    1.0.1 • Public • Published

    OpenBCI Rx

    Reactive Extensions for OpenBCI in Node

    Dependencies Prerequisites

    Make sure you have Node version >= 7.8 installed for development purpose.

    Getting started

    This library works with the following OpenBCI hardware:

    Get started by importing the module:

    npm install --save openbci-rx
    const { Cyton, Ganglion } = require('openbci-rx');
     
    // Or with an alias...
     
    const BrainObservable  = require('openbci-rx').Ganglion;

    Examples

    Basic usage

    const { Cyton } = require('openbci-rx');
     
    async function init () {
        // Same options accepted by 'openbci'
        const cyton = new Cyton({
            verbose: true,
            simulate: true
        });
     
        await cyton.connect();
        await cyton.start();
     
        cyton.stream.subscribe(sample =>
            console.log('sample', sample)
        );
    }
     
    init();

    Adding operators

    ** All operators from this library have been migrated to the eeg-pipes project. Now these can be used as "lettable" RxJS operators. **

     
    // npm install --save eeg-pipes
    import { voltsToMicrovolts, bufferFFT, alphaRange } from 'eeg-pipes';
     
    cyton.stream.pipe(
        voltsToMicrovolts(),
        bufferFFT({ bins: 256 })
        alphaRange()
    ).subscribe(buffer =>
        console.log(buffer)
    );

    And now we have an FFT buffer of Alpha waves!
