wave8_transpose_2()

FASTLED_FORCE_INLINE FL_IRAM FL_OPTIMIZE_FUNCTION void fl::detail::wave8_transpose_2	(	const Wave8Byte	lane_waves[2],
		u8	output[2 *sizeof(Wave8Byte)] )

Transpose 2 lanes of Wave8Byte data into interleaved format.

Parameters

lane_waves	Array of 2 Wave8Byte structures (lane[0]=even bits, lane[1]=odd bits)
output	Output buffer (16 bytes)
