Classes
struct	fl::SinCos32

Namespaces
namespace	fl
	Base definition for an LED controller.

Functions
FASTLED_FORCE_INLINE i16	fl::cos16lut (u16 angle) FL_NOEXCEPT
FASTLED_FORCE_INLINE i32	fl::cos32 (u32 angle) FL_NOEXCEPT
struct	fl::FL_ALIGNAS (16) SinCos32_simd
	Combined sin+cos result for 4 angles (raw SIMD primitives)
FASTLED_FORCE_INLINE i32	fl::read_sin32_lut (const i32 *addr) FL_NOEXCEPT
FASTLED_FORCE_INLINE i16	fl::sin16lut (u16 angle) FL_NOEXCEPT
FASTLED_FORCE_INLINE i32	fl::sin32 (u32 angle) FL_NOEXCEPT
FASTLED_FORCE_INLINE i32	fl::sin32_interp (u8 qi, u8 qi_next, i32 dmask, u32 t, u8 offset=0) FL_NOEXCEPT
FASTLED_FORCE_INLINE SinCos32	fl::sincos32 (u32 angle) FL_NOEXCEPT
FASTLED_FORCE_INLINE SinCos32_simd	fl::sincos32_simd (simd::simd_u32x4 angles) FL_NOEXCEPT
	Process 4 angles simultaneously, returning vectorized sin/cos values SIMD-optimized: vectorized angle decomposition, vector LUT loads with 4x4 transpose (AoS→SoA), and vectorized quadratic interpolation.

Variables
const i32	fl::sinCosPairedLut []
