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)

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.

Installation

As a prerequisite to using nimi-python modules, you must install the corresponding driver runtime on your system. Visit ni.com/downloads to download the driver runtime for your devices.

The nimi-python modules (i.e. for NI-DMM) can be installed with pip:

$ python -m pip install nidmm

Or easy_install from setuptools:

$ python -m easy_install nidmm

Contributing

We welcome contributions! You can clone the project repository, build it, and install it by following these instructions.

Usage

The following is a basic example of using the nidmm module to open a session to a DMM and perform a 5.5 digits of resolution voltage measurement in the 10 V range.

import nidmm
with nidmm.Session("Dev1") as session:
    session.configureMeasurementDigits(nidmm.Function.DC_VOLTS, 10, 5.5)
    print("Measurement: " + str(session.read()))

Additional examples for each driver are located in src/<driver>/examples/ directory.
