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.configureMeasurementDigits(nidmm.Function.DC_VOLTS, 10, 5.5)
print("Measurement: " + str(session.read()))Other usage examples can be found on GitHub.
