class ophyd_async.epics.eiger.Odin(prefix: str, name: str = '')[source]#

Common base class for all Ophyd Async Devices.

Parameters:

class ophyd_async.epics.eiger.OdinWriter(path_provider: PathProvider, odin_driver: Odin, eiger_bit_depth: SignalR[int])[source]#

Logic for making detector write data to somewhere persistent (e.g. HDF5 file).

async open(name: str, exposures_per_event: int = 1) → dict[str, DataKey][source]#

Open writer and wait for it to be ready for data.

Parameters:: exposures_per_event – Each StreamDatum index corresponds to this many written exposures
Returns:: Output for describe()

async observe_indices_written(timeout: float) → AsyncGenerator[int, None][source]#

async get_indices_written() → int[source]#: Get the number of indices written.

abstractmethod collect_stream_docs(name: str, indices_written: int) → AsyncIterator[StreamAsset][source]#: Create Stream docs up to given number written.

async close() → None[source]#: Close writer, blocks until I/O is complete.

class ophyd_async.epics.eiger.Writing[source]#

All members should exist in the Backend, and there will be no extras.
