class ophyd_async.epics.adcore.DetectorState(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)

Default set of states of an AreaDetector driver. See definition in ADApp/ADSrc/ADDriver.h in areaDetector/ADCore

class ophyd_async.epics.adcore.NDPluginStatsIO(prefix: str, name: str = '')

Plugin for computing statistics from an image or region of interest within an image.

async ophyd_async.epics.adcore.set_exposure_time_and_acquire_period_if_supplied(controller: DetectorControl, driver: ADBaseIO, exposure: float | None = None, timeout: float = 10.0) → None

Sets the exposure time if it is not None and the acquire period to the exposure time plus the deadtime. This is expected behavior for most AreaDetectors, but some may require more specialized handling.

Parameters:

• controller – Controller that can supply a deadtime.

• driver – The driver to start acquiring. Must subclass ADBaseIO.

• exposure – Desired exposure time, this is a noop if it is None.

• timeout – How long to wait for the exposure time and acquire period to be set.

async ophyd_async.epics.adcore.start_acquiring_driver_and_ensure_status(driver: ADBaseIO, good_states: frozenset[DetectorState] = frozenset({DetectorState.Aborted, DetectorState.Idle}), timeout: float = 10.0) → AsyncStatus

Start acquiring driver, raising ValueError if the detector is in a bad state.

This sets driver.acquire to True, and waits for it to be True up to a timeout. Then, it checks that the DetectorState PV is in DEFAULT_GOOD_STATES, and otherwise raises a ValueError.

Parameters:

• driver – The driver to start acquiring. Must subclass ADBaseIO.

• good_states – set of states defined in DetectorState enum which are considered good states.

• timeout – How long to wait for driver.acquire to readback True (i.e. acquiring).

Returns:

An AsyncStatus that can be awaited to set driver.acquire to True and perform subsequent raising (if applicable) due to detector state.

Return type:

AsyncStatus
