chrono.h File Reference

Detailed Description

FastLED chrono implementation - duration types for time measurements.

This header provides a minimal chrono implementation compatible with std::chrono, allowing FastLED to use duration types without directly depending on <chrono>. The implementation is intentionally compatible with std::chrono for interoperability.

Functions
template<typename ToDuration, typename Rep, typename Period>
constexpr ToDuration	fl::chrono::duration_cast (const duration< Rep, Period > &d) FL_NOEXCEPT
	Cast one duration type to another.
fl::u32	fl::micros () FL_NOEXCEPT
	Universal microsecond timer - returns microseconds since system startup.
fl::u32	fl::millis () FL_NOEXCEPT
	Universal millisecond timer - returns milliseconds since system startup.
fl::u64	fl::millis64 () FL_NOEXCEPT
	64-bit millisecond timer - returns milliseconds since system startup without wraparound
fl::u64	fl::time () FL_NOEXCEPT
	Alias for millis64() - returns 64-bit millisecond time.
