Classes
class	fl::AsyncLogger
	ISR-safe async logger wrapper (zero heap allocation) Uses embedded AsyncLogQueue instead of heap-allocated pointer Registers itself automatically in ActiveLoggerRegistry on first access. More...
struct	fl::detail::ActiveLoggerRegistry
	Active logger registry for iteration (flush operations) Only tracks loggers that have been instantiated via template access. More...
class	fl::detail::AsyncLoggerServiceTask
	Auto-instantiating task for async logger servicing Registers itself with fl::task::Scheduler when first accessed Only instantiated if at least one async logger is used (linker removes if unused) More...
struct	fl::detail::AudioLoggerInfo
struct	fl::detail::FlexIOLoggerInfo
struct	fl::detail::InterruptLoggerInfo
struct	fl::detail::ObjectFLEDLoggerInfo
struct	fl::detail::ParlioLoggerInfo
	Info providers for each logger category Used to supply category name, define name, and enabled status. More...
struct	fl::detail::RmtLoggerInfo
struct	fl::detail::SpiLoggerInfo

Namespaces
namespace	fl
	Base definition for an LED controller.
namespace	fl::detail
	Compile-time linker keep-alive hook for a single fl::Bus.

Enumerations
enum class	fl::LogCategory : fl::u8 {   fl::PARLIO_ISR = 0 , fl::PARLIO_MAIN = 1 , fl::RMT_ISR = 2 , fl::RMT_MAIN = 3 ,   fl::SPI_ISR = 4 , fl::SPI_MAIN = 5 , fl::AUDIO_ISR = 6 , fl::AUDIO_MAIN = 7 ,   fl::INTERRUPT_ISR = 8 , fl::INTERRUPT_MAIN = 9 , fl::MAX_CATEGORIES = 10 }
	Logger category identifiers for registry-based access Each category has separate ISR and main thread loggers (SPSC requirement) More...

Functions
template<typename InfoProvider>
void	fl::detail::checkLoggerEnabled ()
	Check if logger is enabled and print error once if not.
template<fl::size N, typename InfoProvider>
AsyncLogger &	fl::get_async_logger_by_index ()
	Template-based logger accessor with auto-registration and enablement check.
AsyncLogger &	fl::get_audio_async_logger_isr ()
AsyncLogger &	fl::get_audio_async_logger_main ()
AsyncLogger &	fl::get_flexio_async_logger_isr ()
AsyncLogger &	fl::get_flexio_async_logger_main ()
AsyncLogger &	fl::get_interrupt_async_logger_isr ()
AsyncLogger &	fl::get_interrupt_async_logger_main ()
AsyncLogger &	fl::get_objectfled_async_logger_isr ()
AsyncLogger &	fl::get_objectfled_async_logger_main ()
AsyncLogger &	fl::get_parlio_async_logger_isr ()
AsyncLogger &	fl::get_parlio_async_logger_main ()
AsyncLogger &	fl::get_rmt_async_logger_isr ()
AsyncLogger &	fl::get_rmt_async_logger_main ()
AsyncLogger &	fl::get_spi_async_logger_isr ()
AsyncLogger &	fl::get_spi_async_logger_main ()
void	fl::detail::printLoggerDisabledError (const char *category_name, const char *define_name)
	Print error message for disabled logger (non-template helper) Called from checkLoggerEnabled template function IMPORTANT: This must NOT be inline - needs external linkage for cross-TU calls.
