◆ begin()

bool pulsewire::RecorderCodec::begin ( uint16_t bitFrequencyHz )

initialization method for codecs that require setup before use (e.g., loading PIO programs, configuring state machines).

Reimplemented from pulsewire::Codec.

Definition at line 28 of file RecorderCodec.h.

◆ clear()

void pulsewire::RecorderCodec::clear ( )

Definition at line 39 of file RecorderCodec.h.

◆ decodeByte()

bool pulsewire::RecorderCodec::decodeByte	(	Vector< OutputEdge > &	edges,
		uint8_t &	result
	)

inlineoverridevirtual

Decode edges into a byte.

Implements pulsewire::Codec.

Definition at line 45 of file RecorderCodec.h.

◆ decodeEdge()

bool pulsewire::RecorderCodec::decodeEdge	(	uint32_t	durationUs,
		bool	level,
		uint8_t &	result
	)

inlineoverridevirtual

Edge-based decoding for protocol-agnostic RX drivers.

Called on each signal edge (duration since last edge, new level, minUs, maxUs). The codec maintains its own state and assembles frames internally.

Parameters

durationUs	Time in microseconds since last edge.
level	New logic level after the edge (true = HIGH, false = LOW).
frameBuffer	Output buffer for decoded frame (if available).
frameBufferSize	Size of frameBuffer (bytes).
frameLen	Set to decoded frame length if a frame is available.

Returns: True if a complete frame is decoded and available in frameBuffer.

Reimplemented from pulsewire::Codec.

Definition at line 24 of file RecorderCodec.h.

◆ encode()

virtual size_t pulsewire::Codec::encode	(	uint8_t	byte,
		Vector< OutputEdge > &	output

inlinevirtualinherited

Fill output vector with protocol-specific OutputSpec(s) for a byte.

Encodes the byte to protocol bits and appends OutputSpec(s) for each bit.

Parameters

byte	The byte to encode.
output	Vector to append OutputSpec(s).

Returns: Number of OutputSpec entries added.

Reimplemented in pulsewire::NRZCodec.
