| Info | Python bindings for NI Modular Instrument drivers. See GitHub for the latest source. |
| Author | National Instruments |
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)
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 only the Windows operating system.
** nimi-python** supports CPython 3.6+. * TODO(marcoskirsch): Add PyPI version here.*
In order to use nimi-python modules, you must install the corresponding driver runtime on your system. Visit ni.com/downloads to download the latest driver version for your devices.
Specific Python bindings (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 download the project source, build, and run:
$ python TODO(marcoskirsch): how do we build? $ python setup.py install
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()))The packages included in nimi-python package are supported by NI. For support, open a request through the NI support portal at ni.com.

$ 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.
