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.
- 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.
- Sync to screen : bool
- Whether to synchronize the pump operations (starting, stopping) to the
screen refresh. This ensures better synchronization with visual stimuli.
