About

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

  • NI-DCPower (Python module: nidcpower)
  • NI-DMM (Python module: nidmm)
  • NI-FGEN (Python module: nifgen)
  • NI-SCOPE (Python module: niscope)
  • NI-SWITCH (Python module: niswitch)
  • NI-ModInst (Python module: nimodinst)
  • NI Switch Executive (Python module: nise)

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 supports Python 2.7, 3.4 and later using CPython or PyPy.

$ python -m pip install niswitch~=1.1.2

Or easy_install from setuptools:

$ python -m easy_install niswitch

Usage

The following is a basic example of using the niswitch module to open a session to a Switch and connect channels.

import niswitch
with niswitch.Session("Dev1") as session:
    session.connect(channel1='r0', channel2='c0')

Additional examples for NI-SWITCH are located in src/niswitch/examples/ directory.
