`DemoStage`	A simulated sample stage with X and Y movables.
`EnergyMode`	Energy mode for `DemoPointDetectorChannel`.
`DemoPointDetectorChannel`	A channel for `DemoPointDetector` with int value based on X and Y Motors.
`DemoPointDetector`	A demo detector that produces a point values based on X and Y motors.

Functions#

start_ioc_subprocess

API#

class ophyd_async.epics.demo.DemoMotor(prefix: str, with_pvi: bool = False, name: str = '')[source]#

Bases: ophyd_async.epics.core.EpicsDevice, ophyd_async.core.StandardReadable, ophyd_async.core.StandardMovable

A demo movable that moves based on velocity.

readback: Annotated[SignalR[float], PvSuffix('Readback'), HINTED_SIGNAL]#: None

velocity: Annotated[SignalRW[float], PvSuffix('Velocity'), CONFIG_SIGNAL]#: None

setpoint: Annotated[SignalRW[float], PvSuffix('Setpoint')]#: None

stop_: Annotated[TriggerableCommand, PvSuffix('~Stop.PROC')]#: None

movable_logic() → MovableLogic#

The logic object that describes how this device moves.

This is intentionally public so that mock helpers (e.g. InstantMovableMock) and subclasses can access the setpoint and readback signals directly. Subclasses must implement this as a @cached_property that returns a MovableLogic instance.
