Detailed Description

Abstract interface for persisting timestamped data points.

Note

When to use: derive from this class to implement a specific persistence backend (e.g., SD card, SPI flash, telemetry).

Member Function Documentation

begin()

virtual bool IDataSaver::begin ( )

inlinevirtual

Optional hook for initialization.

Note

When to use: override if the saver needs hardware/filesystem setup before use.

Reimplemented in DataSaverBigSD, and DataSaverSPI.

Definition at line 42 of file DataSaver.h.

launchDetected()

virtual void IDataSaver::launchDetected ( uint32_t launchTimestamp_ms )

inlinevirtual

Notification that launch has been detected.

Parameters

launchTimestamp_ms

Timestamp of launch, in milliseconds.

Note

When to use: override to change write policy once launch is confirmed (e.g., lock buffers or mark critical data).

Reimplemented in DataSaverSPI.

Definition at line 52 of file DataSaver.h.

saveDataPoint() [1/2]

virtual int IDataSaver::saveDataPoint ( const DataPoint & dp, uint8_t name )

pure virtual

Persist a data point with a source identifier.

Parameters

dp	Data point to store.
name	8-bit identifier (sensor/channel) saved alongside the value.

Note

When to use: primary write path for subclasses; implement in each concrete saver.

Implemented in DataSaverBigSD, DataSaverMock, DataSaverSDSerial, DataSaverSPI, and printSaver.

saveDataPoint() [2/2]

virtual int IDataSaver::saveDataPoint ( float data, uint32_t timestamp_ms, uint8_t name )

inlinefinalvirtual

Convenience overload to construct and save a data point.

Parameters

data	Measurement value.
timestamp_ms	Timestamp of the measurement in milliseconds.
name	8-bit source identifier.

Note

When to use: callers that have raw values but not a DataPoint object.

Reimplemented in DataSaverSDSerial.

Definition at line 33 of file DataSaver.h.
