| Info | Python bindings for NI Modular Instrument drivers. See GitHub for the latest source. |
| Author | NI |
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.

Driver specific installation instructions can be found on Read The Docs:
We welcome contributions! You can clone the project repository, build it, and install it by following these instructions.
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()))Other usage examples can be found on GitHub.
