fluidlab.interfaces¶
Interfaces with the instruments (fluidlab.interfaces
)¶
Provides some classes:
- class fluidlab.interfaces.PhysicalInterfaceType(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)[source]¶
Provides some functions:
- fluidlab.interfaces.set_default_interface(interface_type, interface_classname)[source]¶
Select the default class interface for the given interface type. By default, GPIB uses VISAInterface class on Windows (based on NI-VISA) and GPIBInterface class on Linux (based on Linux-GPIB), Ethernet uses SocketInterface class, Seriel uses SerialInterface class.
This means that GPIB instrument can be instantiated as Instrument(‘GPIB0::1::INSTR’) instead of Instrument(VISAInterface(‘GPIB0::1::INSTR’)) or Instrument(GPIBInterface(0,1)), provided the Instrument class defines Instrument.default_physical_interface to PhysicalInterfaceType.GPIB.
The behavior can be changed by this function, i.e. import fluidlab.interfaces as fi fi.set_default_interface(fi.PhysicalInterface.GPIB, ‘VISAInterface’) to force VISAInterface on Linux, or fi.set_default_interface(fi.PhysicalInterface.Ethernet, ‘VISAInterface’) to use VISAInterface class instead of SocketInterface class for network connected devices.
- fluidlab.interfaces.interface_from_string(name, default_physical_interface=None, **kwargs)[source]¶
Infer physical_interface from name if possible, or use the default provided physical_interface otherwise. i.e. if the names contains the physical interface explicitely, then we use it, eg. GPIB0::1::INSTR is GPIB physical interface ASRL0::INSTR is a VISA Serial address 192.168.0.1 is a IP address, so Ethernet interface
