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 the nifgen module, you must install the NI-FGEN runtime on your system. Visit ni.com/downloads to download the driver runtime for your devices.

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

$ python -m pip install nifgen

Or easy_install from setuptools:

$ python -m easy_install nifgen

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 nifgen module to open a session to a Function Generator and generate a sine wave for 5 seconds.

import nifgen
import time
with nifgen.Session("Dev1") as session:
    session.output_mode = nifgen.OutputMode.FUNC
    session.configure_standard_waveform(waveform=nifgen.Waveform.SINE, amplitude=1.0, frequency=10000000, dc_offset=0.0, start_phase=0.0)
    with session.initiate():
        time.sleep(5)

Additional examples for NI-FGEN are located in src/nifgen/examples/ directory.
