DEWESoft produces hardware and software for test measurement, data aquisition, and storage. Data files are stored with the extension .d7d in a proprietary format. DEWESoft provides a free Windows application to work with the data and a free shared library for developers on Windows and Linux.

This is a Python module to interact with the DEWESoft DWDataReaderLib shared library available from http://www.dewesoft.com/developers

The module is available on https://pypi.python.org/pypi/dwdatareader so all one needs to do is:

pip install dwdatareader

Scripts like the following may be run from the command line or, more interactively, from Jupyter Notebook

import dwdatareader as dw
with dw.open('myfile.d7d') as f:
    print(f.info)
    ch1 = f['chname1'].series()
    ch1.plot()
    for ch in f.values():
        print(ch.name, ch.series().mean())
