.. _pumpComponent:
Pump Component
--------------
This component allows you to deliver liquid stimuli using a Cetoni neMESYS syringe pump.
Please specify the name of the pump configuration to use in the |PsychoPy|
preferences under ``Hardware / Qmix pump configuration``. See the `readme file`_ of
the ``pyqmix`` project for details on how to set up your computer and create
the configuration file.
Properties
~~~~~~~~~~
Name : string
Everything in a |PsychoPy| experiment needs a unique name. The name should contain only letters, numbers and underscores (no punctuation marks or spaces).
Start :
The time that the stimulus should first appear.
Stop :
Governs the duration for which the stimulus is presented.
Sync to screen : bool
Whether to synchronize the pump operations (starting, stopping) to the
screen refresh. This ensures better synchronization with visual stimuli.
Hardware
========
Parameters for controlling hardware.
Pump index : int
The index of the pump: The first pump's index is 0, the second pump's index is 1, etc.
You may insert the name of a variable here to adjust this value dynamically.
Syringe type : select the appropriate option
Currently, 25 mL and 50 mL glass syringes are supported. This setting ensures that
the pump will operate at the correct flow rate.
Pump action : ``aspirate`` or ``dispense``
Whether to fill (``aspirate``) or to empty (``dispense``) the syringe.
Flow rate : float
The flow rate in the selected flow rate units.
Flow rate unit : ``mL/s`` or ``mL/min``
The unit in which the flow rate values are supplied.
Switch valve after dosing : bool
Whether to switch the valve osition after the pump operation has
finished. This can be used to ensure a sharp(er) stimulus offset.
