show()

virtual void fl::IChannelDriver::show ( )

pure virtual

Trigger transmission of enqueued data.

Note

May block depending on current driver state (poll() returns BUSY/DRAINING)

Typical behavior: Wait for hardware to be READY, then transmit all enqueued data

Implemented in fl::anonymous_namespace{channel.cpp.hpp}::StubChannelEngine, and fl::SpiChannelEngineAdapter.
