1.2.0

New Features

  • Add tutorial/sample code for interfacing the module with lab streaming layer.

Breaking Changes

  • Fixed time synced accel to work OpenBCI_32bit_Library release candidate 5 and newer.

1.1.0

New Features

  • Add function .time() which should be used in time syncing
  • Add function .syncClocksFull() which should be used for immediate consecutive time syncs
  • Synced object can be emitted on synced event. Check valid property for if the sync was done
  • Add detailed description of object returned on synced event to README.md

Breaking Changes

  • Changed option named timeSync to sntpTimeSync
  • Removed function called .sntpNow() because it was replaced by .time()

Bug Fixes

  • Time sync working
  • Module could not work with local time

1.0.1

New Features

  • Add time sync tutorial in README.md

Bug Fixes

  • Fixed bug in simulator that lead to samples being all zeros.
  • Fixed time sync sent confirmation bug that led to bad time values.

1.0.0

The second major release for the OpenBCI Node.js SDK brings major changes, improvements and stability, on top of a push to increase automated test coverage.

New Features

  • NPM Module now called openbci instead of openbci-sdk
  • Firmware version 2.0 support.
  • Clock synchronization between OpenBCI board and this driver
  • .info property which contains verified board information parsed from the OpenBCI's softReset() response.
  • eot event that is emitted when a user sends a command that results in an EOT ("$$$") being sent from the board
  • Daisy (16 channel) support
  • Simulator overhaul, it completely mocks the board. Can now simulate board failure, where the board stops talking to the dongle. Can also mock a serial port failure.
  • error and close events from serialport now emtted events users can subscribe to.

Breaking Changes

  • NPM package is not called openbci-sdk anymore, now called openbci
  • Accelerometer data now goes into .accelData array instead of .auxData array.
  • In openBCISample.js
    • parseRawPacket() is now called parseRawPacketStandard()
  • ready event only triggered after soft reset. eot event emitted in all other conditions resulting in the board sending EOT ("$$$")
  • Must use camel case on the OpenBCISimulator object.
  • Renamed constructor options for readability:
    • simulatorAlpha to simulatorInjectAlpha
    • simulatorLineNoise to simulatorInjectLineNoise
  • connect() no longer rejects on close or error event from the serialport.

0.3.9

Enhancements

  • Add tests for parsing raw packets

Bug Fixes

  • Removed got here log from .streamStart()
  • Validate stop byte before emitting rawDataPacket

0.3.8

Bug Fixes

  • Fixed readme.md

0.3.7

New Features

  • Upgrade dependencies
  • Update Travis

Bug Fixes

  • .numberOfChannels() now uses the info object, which is set in the constructor and on the return message from .softReset()
  • .sampleRate() now uses the info object, which is set in the constructor and on the return message from .softReset()

0.3.6

New Features

  • Simulator now has accelerometer data

0.3.5

New Features

  • SD card support! Now logging to an SD card is easier than ever.

Bug Fixes

  • Sample rate does not return correct sample rate for custom rate on simulator. #58

0.3.4

New Features

  • Simulator made to look more like brainwave data to the user. Implemented a 1/f filter. Defaults to injecting 60Hz line noise with two channels of alpha (10Hz) boost.

Github Issues Addressed

0.3.3

Bug Fixes

  • rawDataPacket not being emitted

0.3.2

Work In Progress

  • SNTP Time Synchronization

Bug Fixes

  • updates to README.me and comments to change ntp to sntp, because the two are similar, but not the same and we do not want to be misleading
  • Extended Stnp to main openBCIBoard.js
  • Add .sntpNow() function to get ntp time.

0.3.1

Bug Fixes

  • Bumped serialport version

0.3.0

New Features

  • Test Signals with ADS1299 using .testSignal()
  • Continuous impedance testing, where each sample gets an impedances object that is an array of impedances for each channel.
  • OpenBCI Radio Test File
  • Added Sntp npm module with helper functions
  • Removed stopByte and startByte from sampleObjects

Breaking Changes

  • Changed simulator name to OpenBCISimulator
  • Changed name of function simulatorOn to simulatorEnable
  • Changed name of function simulatorOff to simulatorDisable

Work In Progress

  • NTP Time Synchronization
  • Goertzel algorithm to get voltage for impedance calculation

Bug fixes

  • Impedance calculations
  • Readme updates
  • Serial buffer had the chance to become permanently unaligned, optimized and completely transformed and refactored the way bytes are processed.
  • Changes to gain of channels not working correctly.
  • Node 5 compatibility
