About

The nimi-python repository generates Python bindings (Application Programming Interface) for interacting with the Modular Instrument drivers. The following drivers are supported:

• NI-DCPower (Python module: nidcpower)

• NI-Digital Pattern Driver (Python module: nidigital)

• NI-DMM (Python module: nidmm)

• NI-FGEN (Python module: nifgen)

• NI-ModInst (Python module: nimodinst)

• NI-SCOPE (Python module: niscope)

• NI Switch Executive (Python module: nise)

• NI-SWITCH (Python module: niswitch)

• NI-TClk (Python module: nitclk)

It is implemented as a set of Mako templates and per-driver metafiles that produce a Python module for each driver. The driver is called through its public C API using the ctypes Python library.

nimi-python supports all the Operating Systems supported by the underlying driver.

nimi-python follows Python Software Foundation support policy for different versions. At this time this includes Python 3.5 and above using CPython.

$ python -m pip install nidigital~=0.5.0

Or easy_install from setuptools:

$ python -m easy_install nidigital

Usage

The following is a basic example of using the nidigital module to open a session to a ….

import nidigital
with nidigital.Session(resource_name='PXI1Slot2', channels='0') as session:
    pass

Some repeated capabilities can be chained. This is useful for some methods that can be used with the pins repeated capability. They can be chained with the sites repeated capability.

import nidigital
# Configure the session.

with nidigital.Session(resource_name='PXI1Slot2', channels='0') as session:
    session.sites[0, 1].pins['PinA', 'PinB'].ppmu_source()

This will apply the method/property to ‘site0/PinA, site0/PinB, site1/PinA, site1/PinB’

Additional examples for NI-Digital Pattern Driver are located in src/nidigital/examples/ directory.
