Node Examples

Node Installation

See the getting started repo for full scripts. We used Node.js 10.15.3 for these examples. If you don't use LSL, you can probably use versions 14.15.1+.

Install the dependencies:

npm install

Script Examples

This script receives an LSL EEG stream and prints it to console.

node lsl_receive.js -n SimulatedEEGStream
node lsl_receive.js -n PetalStream_gyroscope
node lsl_receive.js -n PetalStream_ppg
node lsl_receive.js -n PetalStream_telemetry
node lsl_receive.js -n PetalStream_eeg
node lsl_receive.js -n PetalStream_acceleration
node lsl_receive.js -n PetalStream_connection_status

This script streams 4 channels of EEG data at a selected sample rate. It can stream randomly generated data, or from a CSV file with any header where the first 4 columns represent channels 1-4.

  • Random EEG data at 256Hz:

node lsl_stream.js -s 256
  • From a CSV file at 256Hz:

node lsl_stream.js -s 256 -f ../example_data.csv
