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)

class fluidlab.interfaces.Interface(**kwargs)

class fluidlab.interfaces.QueryInterface(**kwargs)

class fluidlab.interfaces.FalseInterface(**kwargs)

Dummy interface

Provides some functions:

fluidlab.interfaces.set_default_interface(interface_type, interface_classname)

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)

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

Provides some modules:

gpib_inter	Interfaces with GPIB (fluidlab.interfaces.gpib_inter)
modbus_inter	Modbus interfaces (fluidlab.interfaces.modbus_inter)
serial_inter	Interfaces with serial (fluidlab.interfaces.serial_inter)
socket_inter	Interfaces with socket (fluidlab.interfaces.socket_inter)
usbtmc_inter	Interface with Linux USBTMC (fluidlab.interface.usbtmc_inter)
visa_inter	Interfaces with VISA (fluidlab.interfaces.visa_inter)
