About

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

• NI-DCPower (Python module: nidcpower)

• NI-Digital Pattern Driver (Python module: nidigital)

• NI-DMM (Python module: nidmm)

• NI-FGEN (Python module: nifgen)

• NI-ModInst (Python module: nimodinst)

• NI-SCOPE (Python module: niscope)

• NI Switch Executive (Python module: nise)

• NI-SWITCH (Python module: niswitch)

• NI-TClk (Python module: nitclk)

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 follows Python Software Foundation support policy for different versions. At this time this includes Python 3.7 and above using CPython.

Installation

As a prerequisite to using the nimodinst module, you must install the NI-ModInst runtime on your system. Visit ni.com/downloads to download the driver runtime for your devices.

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

$ python -m pip install nimodinst~=1.4.5

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 nimodinst module to retrieve information on all High Speed Digitizers currently in the system.

import nimodinst
with nimodinst.Session("niscope") as session:
    for device in session:
        print("{: >20} {: >15} {: >10}".format(device.device_name, device.device_model, device.serial_number))

Other usage examples can be found on GitHub.
