instance()

ChannelManager & fl::ChannelManager::instance ( )

static

Get the global singleton instance.

Returns

Reference to the singleton ChannelManager

Note

Thread-safe singleton initialization

The first call registers the platform's default channel drivers (platforms::initChannelDrivers()). Runtime-selection callers (FastLED.add(cfg), driver queries, Channel dispatch) use this.
