Crate culvert_async 

Async typed access to the HDMI 2.1 SCDC (Status and Control Data Channel) register map.

culvert-async is the async companion to culvert, following the same design split as embedded-hal / embedded-hal-async. It mirrors culvert::Scdc with async fn methods, wrapping an hdmi_hal_async::scdc::ScdcTransport instead of a sync transport.

All register types and error types are re-exported from culvert so that callers do not need to depend on both crates.

Features

• plumbob-async — implements plumbob_async::ScdcClient for Scdc<T>, connecting culvert-async to the async FRL link training state machine.
