encodeWS2801()

template<typename InputIterator, typename OutputIterator>

void fl::encodeWS2801	(	InputIterator	first,
		InputIterator	last,
		OutputIterator	out )

Encode pixel data in WS2801/WS2803 format.

Writes RGB pixel data in WS2801 protocol format. WS2801 is one of the simplest SPI protocols - just 3 bytes per LED (RGB) with no start/end frames. Latching occurs via timing (pause in clock).

Template Parameters

InputIterator	Iterator yielding fl::array<u8, 3> (3 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

WS2803 uses identical protocol to WS2801 (just different default clock speed)

Writes 3 bytes per pixel in wire order

WS2801 uses RGB wire order: pixel[0]=Red, pixel[1]=Green, pixel[2]=Blue

        ++first;
    }
    // No end frame needed - WS2801 latches via timing (clock pause)
