Kernel SDK

Prev Next

The Kernel SDK allows you to programmatically subscribe to real-time data and assists in sending task events. For manually sending task events in your own language of choice, see Kernel Tasks SDK.

Currently, only Python is supported with more languages on the roadmap.

Features

Subscribe to real-time data

  • 3 fNIRS moments across both wavelengths and all channels — individually or all six streams at once, time-aligned
  • Noise floor removed, bad channels removed
  • EEG voltage and impedance across all channels
  • Task events received through the Tasks SDK
  • Coupling signal indicator

Send task events

  • Experiment, block, and trial structure with automatic counters and start/end pairs
  • Inter-trial intervals, rest, cue, stimulus, reaction time, and photodiode sync

Run "happy path" commands

  • Initialize, tune, and toggle lasers
  • Guided end-to-end workflow, online or fully offline with no data leaving the machine

Query the device

  • Get currently available modules
  • Get EEG channel names and layout, and Flow source/detector geometry in 2-D and 3-D

Track connection and device state

  • USB and system state, as properties or subscriptions
  • Auto-reconnect and typed errors

Control a syncbox

  • 8 channels of digital I/O, analog input, and comparator triggering
  • Digital, comparator, and analog telemetry streams
