wave3_transpose_16()

FASTLED_FORCE_INLINE FL_IRAM FL_OPTIMIZE_FUNCTION void fl::detail::wave3_transpose_16	(	const Wave3Byte	lane_waves[16],
		u8	output[16 *sizeof(Wave3Byte)] )

Transpose 16 lanes of Wave3Byte data into interleaved format.

Parameters

lane_waves	Array of 16 Wave3Byte structures
output	Output buffer (48 bytes = 16 * 3)

Spread-LUT transpose (#2533): ~1.9× faster than the unrolled naive on the ESP32-P4 (RV32), bit-exact. See bit_spread_lut.hpp. Each 16-lane sample is 2 output bytes: low = lanes 0-7, high = lanes 8-15. (wave3 = 3 symbols.)

            l[lane] = lane_waves[lane].data[symbol_idx];
        }
