Detailed Description

FourTrackRecorder records four motion streams to an SD card file.

The FourTrackRecorder class allows simultaneous recording of four motion streams to an SD card file. Each track can be mapped to a BlockPort for input. The recorder supports starting, pausing, resuming, and stopping recordings, as well as setting the resolution for recording. Recorded data is stored in a binary format on the SD card for efficient storage and retrieval. It is typically used in conjunction with the FourTrackPlayer class for playback of recorded motion streams. Here's an example of how to instantiate and configure a FourTrackRecorder: AxiDraw Recorder Example.

Member Function Documentation

set_resolution()

void FourTrackRecorder::set_resolution	(	float	input_units,
		float	per_steps = 1.0 )

Sets the resolution for recording in world units per step.

Parameters

input_units	World units corresponding to one step.
per_steps	Number of steps. Default is 1.0.

start()

void FourTrackRecorder::start	(	const char *	recording_name,
		uint8_t	recording_length_min = 30 )

Starts a new recording with the specified name and optional length.

Parameters

recording_name	Name of the recording file. This should be the same name you provide to the FourTrackPlayer for playback.
recording_length_min	Optional length of the recording in minutes. Default is 30 minutes.
