Detailed Description

Transmission data for a single LED channel.

This lightweight data transfer object holds everything the driver needs to transmit LED data: pin number, timing configuration, and encoded bytes. Separated from Channel to allow concurrent transmission while channels prepare next frame.

	Get the encoded transmission data.

fl::vector_psram< u8 > &	getData () FL_NOEXCEPT
	Get the encoded transmission data (mutable)

size_t	getMinimumSize () const FL_NOEXCEPT
	Calculate the size needed for writeWithPadding() without allocating.

int	getPin () const FL_NOEXCEPT
	Get the GPIO pin number.

size_t	getSize () const FL_NOEXCEPT
	Get the data size in bytes.

const ChipsetTimingConfig &	getTiming () const FL_NOEXCEPT
	Get the timing configuration (clockless chipsets only)

bool	isClockless () const FL_NOEXCEPT
	Check if this is a clockless chipset.

bool	isInUse () const FL_NOEXCEPT
	Check if channel data is currently in use by the driver.

bool	isSpi () const FL_NOEXCEPT
	Check if this is an SPI chipset.

void	setInUse (bool inUse) FL_NOEXCEPT
	Mark channel data as in use by the driver.

void	setPaddingGenerator (PaddingGenerator generator) FL_NOEXCEPT
	Set the padding generator for this channel.

void	writeWithPadding (fl::span< u8 > dst) FL_NOEXCEPT
	Write encoded data with padding to destination buffer.

Static Public Member Functions
static ChannelDataPtr	create (const ChipsetVariant &chipset, fl::vector_psram< u8 > &&encodedData=fl::vector_psram< u8 >()) FL_NOEXCEPT
	Create channel transmission data (modern variant-based API)

static ChannelDataPtr	create (int pin, const ChipsetTimingConfig &timing, fl::vector_psram< u8 > &&encodedData=fl::vector_psram< u8 >()) FL_NOEXCEPT
	Create channel transmission data (backwards compatibility)

Private Member Functions
	ChannelData (const ChannelData &) FL_NOEXCEPT=delete

	ChannelData (const ChipsetVariant &chipset, fl::vector_psram< u8 > &&encodedData) FL_NOEXCEPT
	Private constructor - variant-based (modern API)

	ChannelData (int pin, const ChipsetTimingConfig &timing, fl::vector_psram< u8 > &&encodedData) FL_NOEXCEPT
	Private constructor - legacy API (backwards compatibility)

ChannelData &	operator= (const ChannelData &) FL_NOEXCEPT=delete

Private Attributes
ChipsetVariant	mChipset
	Chipset configuration (clockless or SPI)

fl::vector_psram< u8 >	mEncodedData
	Encoded transmission bytes (PSRAM)

volatile bool	mInUse = false
	Engine is transmitting this data (prevents creator updates)

PaddingGenerator	mPaddingGenerator
	Optional padding generator for block-size alignment.
