encodeWS2812_RGBW()

template<typename InputIterator, typename OutputIterator>

void fl::encodeWS2812_RGBW	(	InputIterator	first,
		InputIterator	last,
		OutputIterator	out )

Encode 4-byte pixel data in WS2812 format.

Template Parameters

InputIterator	Iterator yielding fl::array<u8, 4> (4 bytes in wire order)
OutputIterator	Output iterator accepting uint8_t (e.g., fl::back_inserter)

Parameters

first	Iterator to first pixel
last	Iterator past last pixel
out	Output iterator for encoded bytes

Note

Writes 4 bytes per pixel in whatever color order they're already in
