.. _about-section:

:align: center


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

* NI-DMM (Python module: nidmm)
* 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-section:


As a prerequisite to using nimi-python modules, you must install the corresponding driver runtime on your system. Visit ` <>`_ 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

You also can clone the project repository, build it, and install it::

$ git clone
$ make
$ pip install -U bin\nidmm\dist\nidmm-0.1-py2.py3-none-any.whl

.. _usage-section:


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.

.. code-block:: python

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

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

.. _support-section:

Support / Feedback

The packages included in **nimi-python** package are supported by NI. For support, open

`GitHub issues page <>`_.

Information to Include When Asking for Help

Please include **all** of the following information when opening an issue:

- Detailed steps on how to reproduce the problem and full traceback, if
applicable. Code samples are encouraged!

- The python version used::

$ python -c "import sys; print(sys.version)"

- The module (i.e. **nidmm**) and its version::

$ python -m pip list

- The version of the driver used (i.e. **NI-DMM 17.1**). Follow
`this KB article <>`_
to determine the version you have installed.

- The operating system, version, and bitness. For example 64-bit Windows 7.

.. _documentation-section:


Documentation is available `here <>`_.
