Detailed Description

Buffered CSV writer targeting large SD cards via SdFat.

Note

When to use: high-volume logging to removable media where batched writes and periodic syncs reduce wear and latency.

Member Function Documentation

begin()

bool DataSaverBigSD::begin ( )

virtual

Initialize the SD card and open a streaming file. Returns true on success.

Note

When to use: during setup before any calls to saveDataPoint.

Reimplemented from IDataSaver.

Definition at line 11 of file DataSaverBigSD.cpp.

end()

void DataSaverBigSD::end

(

)

Flush pending bytes and close the file.

Note

When to use: before power-off or media removal to avoid loss.

Definition at line 96 of file DataSaverBigSD.cpp.

saveDataPoint()

int DataSaverBigSD::saveDataPoint ( const DataPoint & dataPoint, uint8_t name )

overridevirtual

Buffer a CSV line (timestamp,name,value) and flush in batches.

Parameters

dataPoint	Timestamped value to log.
name	8-bit channel identifier written in the CSV line.

Note

When to use: routine logging path once begin() succeeds.

Implements IDataSaver.
