create()

ChannelPtr fl::Channel::create ( const ChannelConfig & config )

static

Create a new channel with optional mBus driver pinning.

Parameters

config

Channel configuration. If config.options.mBus is not Bus::AUTO, the channel pins itself to the driver named by busName(mBus) via ChannelManager::findDriverByName(). On a miss, showPixels() falls back to AUTO/priority dispatch and emits a one-shot FL_ERROR (see channel.cpp.hpp).

Returns

Shared pointer to channel (auto-cleanup when out of scope)

Note

Channels always use ChannelManager by default.

    // Late binding strategy: Always create with empty driver
