class jaeger.testing.VirtualFPS(*args, **kwargs)[source]#

Bases: 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.

_check_fibre_assignments(*args, **kwargs)[source]#

Checks that all the expected robots are present.

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

Bases: StatusMixIn

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 (int) – The ID of the positioner.

  • centre (tuple | None) – A tuple of two floats indicating where on the focal plane the positioner is located.

  • position (Tuple[float, float]) – A tuple of two floats indicating the angles of the alpha and beta arms.

  • speed (tuple | None) – A tuple of two float indicating the RPM on the input for alpha and beta.

  • firmware (str) – The firmware version, as a string with the format AB.CD.EF.

  • bus (VirtualBus | None) –

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.
