lsl_tools 0.2.1

Lab Streaming Layer tools in pure Dart: a web-safe facade over liblsl, recording to XDF, a WebSocket bridge between networks, test outlets, and the `lsl` command line tool.

0.2.1

• Requires liblsl ^1.1.2.

0.2.0

• Fixed: LslRecorder clock offset did not match standard XDF
• An event-driven inlet's latency is measured until the end of the chunk
• New receiveChunks(inlet, options), stream version of inlet samples.
• The latency in an LSL inlet's ClockChain does not include the wait/polling delay when using event driven mode.
• receiveChunks uses pullIntervalMs for delivery, and slower streams will deliver immediately. pullInterval of Duration.zero will always deliver immediately.
• Bridge protocol 2; source timestamps are kept and a ClockChain gives offset, drift, error bound, latency and jitter per hop.
• The bridge's clock is measured as LSL measures an outlet's (bursts, the fastest round trip) with a drift fit
• Bridge inlets take LslInletOptions: corrected and dejittered time stamps by default, raw ones with clockSync: false.
• lsl bridge publishes a BridgeTiming stream and has --stats.
• New LslDataStreamPump and DataStreamInlet continue a chain through a peer_coordinator session (WebRTC).
• Monotinic clocks are now used instead of wall clocks where LSL is not available (e.g. web).

0.1.0

• Initial version, from signal_viewer_lsl: the lsl facade, LslRecorder, the LSL bridge, test outlets; and the lsl command line tool.
