Testing with jaeger¶

class jaeger.testing.VirtualFPS(can=None, ieb=None)[source]¶

Bases: jaeger.fps.FPS

A mock Focal Plane System for testing and development.

This class listens to a virtual bus and responds as if real positioners were plugged into the system.

Parameters

can (JaegerCAN | str | None) –
ieb (Union[bool, IEB, dict, str, pathlib.Path, None]) –

Return type

class jaeger.testing.VirtualPositioner(positioner_id, bus=None, centre=None, position=(0.0, 0.0), speed=None, firmware='10.11.12')[source]¶

Bases: Generic[jaeger.utils.helpers.Status_co]

A virtual positioner that listen to CAN commands.

An object of VirtualPositioner represents a real positioner firmware. It knows it’s own state at any time and replies.

Parameters

positioner_id – The ID of the positioner.
centre – A tuple of two floats indicating where on the focal plane the positioner is located.
position – A tuple of two floats indicating the angles of the alpha and beta arms.
speed – A tuple of two float indicating the RPM on the input for alpha and beta.
firmware – The firmware version, as a string with the format AB.CD.EF.

is_bootloader()[source]¶: Returns True if the positioner is in bootloader mode.

async process_firmware_data(uid, data)[source]¶: Processes SEND_FIRMWARE_DATA commands.

async process_goto(message)[source]¶: Process an absolute or relative goto command.

async process_message(msg, positioner_id, command_id, uid)[source]¶: Processes incoming commands from the bus.

reset()[source]¶: Resets the positioner.

set_bootloader(bootloader=True)[source]¶: Sets the positioner in bootloader mode.

_initial_status = 17384367873¶: The initial status of the positioner. Represents a positioner that is not moving and is fully calibrated.
