Classes
class	CMinWait< WAIT >
	Class to ensure that a minimum amount of time has kicked since the last time run - and delay if not enough time has passed yet. More...

Macros
Some timing related macros/definitions
#define	CLKS_TO_MICROS(_CLKS)
	Convert from number of clock cycles to microseconds.
#define	F_CPU_MHZ   (F_CPU / 1000000L)
	CPU speed, in megahertz (MHz)
#define	NO_TIME(A, B, C)
	Macro for making sure there's enough time available.
#define	NS(_NS)
	Convert from nanoseconds to number of clock cycles.

Clock cycle counted delay loop
template<fl::cycle_t CYCLES>
void	delaycycles ()
	Delay N clock cycles.
template<fl::cycle_t CYCLES>
FASTLED_FORCE_INLINE void	delaycycles ()
	Delay N clock cycles.
template<fl::cycle_t CYCLES>
void	delaycycles_min1 ()
	A variant of delaycycles that will always delay at least one cycle.
#define	FL_NOP   __asm__ __volatile__ ("nop\n");
	Single no operation ("no-op") instruction for delay.
#define	FL_NOP2   __asm__ __volatile__ ("nop\n\t nop\n");
	Double no operation ("no-op") instruction for delay.
