Note

Ophyd.v2 is included on a provisional basis until the v2.0 release and may change API on minor release numbers before then

ophyd.v2.core#

Core Ophyd.v2 functionality like Device and Signal

Module attributes

A function that will be called with the Reading and value when the monitor updates

Functions

`connect_children`	Call `child.connect(sim)` on all child devices in parallel.
`get_device_children`
`get_dtype`	Get the runtime dtype from a numpy ndarray type annotation
`get_unique`	If all values are the same, return that value, otherwise return TypeError
`merge_gathered_dicts`	Merge dictionaries produced by a sequence of coroutines.
`monitor_sim_value`	Monitor the value of a signal that is in sim mode
`name_children`	Call `child.set_name(child_name)` on all child devices in series.
`observe_value`	Subscribe to the value of a signal so it can be iterated from.
`set_sim_put_proceeds`	Allow or block a put with wait=True from proceeding
`set_sim_value`	Set the value of a signal that is in sim mode
`wait_for_connection`	Call many underlying signals, accumulating `NotConnected` exceptions
`wait_for_value`	Wait for a signal to have a matching value.

Classes

`AsyncReadable`	Readable narrowed to only be async
`AsyncStatus`	Convert asyncio awaitable to bluesky Status interface
`Device`	Common base class for all Ophyd.v2 Devices.
`DeviceCollector`	Collector of top level Device instances to be used as a context manager
`DeviceVector`
`Monitor`	The kind of handle we expect camonitor/pvmonitor to return
`Signal`	A Device with the concept of a value, with R, RW, W and X flavours
`SignalBackend`	A read/write/monitor backend for a Signals
`SignalR`	Signal that can be read from and monitored
`SignalRW`	Signal that can be both read and set
`SignalW`	Signal that can be set
`SignalX`	Signal that puts the default value
`SimMonitor`	Handle that is returned when monitoring a Signal in sim mode
`SimSignalBackend`	An simulated backend to a Signal, created with `Signal.connect(sim=True)`
`StandardReadable`	Device that owns its children and provides useful default behavior.

Exceptions

Exception to be raised if a Device.connect is cancelled
