Interface ITimestampedDataSubscriber
public interface ITimestampedDataSubscriber
The ITimestampedDataSubscriber interface provides a method for consumers
of navX-Model device data to be rapidly notified whenever new data
has arrived.
- timestampedDataReceived(): reception of sensor-timestamped data
A "sensor" timestamp is provided, generated by the navX-Model device, which is
at millisecond resolution. A "system timestamp", also at millisecond resolution,
is also provided, which represents as accurately as possible the time at which the
data was acquired from the navX-Model device. Note that the "system timestamp"
typically has more jitter since it is generated by the host of the navX-Model
device.
Thus, in general sensor timestamps are preferred, as they are generated
by the navX-Model device motion processor and has a greater accuracy (+/- 1ms) than the
system timestamp which is vulnerable to latencies introduced by the
host operating system.
The system timestamp is provided to allow performance monitoring of the
navX-Model device host's data acquisition process.
