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.

Installation

Driver specific installation instructions can be found on Read the Docs:

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.configure_measurement_digits(nidmm.Function.DC_VOLTS, 10.0, 5.5)
    print("Measurement: " + str(session.read()))

Other usage examples can be found on GitHub.
