LabVIEW

This example shows how to access a 32-bit LabVIEW library from 64-bit Python. Labview32 is the 32-bit server and Labview64 is the 64-bit client. The source code of the LabVIEW program is available here.

Attention

This example requires that a 32-bit LabVIEW Run-Time Engine ≥ 2017 is installed and that the operating system is Windows.

Create a Labview64 client to communicate with the 32-bit labview_lib32 library

>>> from msl.examples.loadlib import Labview64
>>> labview = Labview64()

Calculate the mean, the sample variance and the standard deviation of some data, see Labview64.stdev

>>> data = [1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> labview.stdev(data)
(5.0, 7.5, 2.7386127875258306)

Calculate the mean, the population variance and the standard deviation of data

>>> labview.stdev(data, weighting=1)
(5.0, 6.666666666666667, 2.581988897471611)

You have access to the server's stdout and stderr streams when you shut down the server

>>> stdout, stderr = labview.shutdown_server32()
