1 This package provides an object-oriented interface to the Comedi_
2 drivers. The standard Python interface bundled with Comedilib is a
3 simple SWIG clone of the C interface. In pycomedi, we convert the
4 functions into class methods (see ``pycomedi.classes``), so you don't
5 have to worry about dragging around opaque types like ``comedi_t *``
6 device pointers. We also bundle related constants together in
7 ``_Enums`` and ``_Flags`` (see ``pycomedi.constants``), to make
8 handling common operations like flag manipulations simpler. Finally,
9 there are a number of utility classes (see ``pycomedi.utility``) to
10 make common tasks like creating instructions or reading hardware-timed
23 I've packaged pycomedi for Gentoo. You need layman_ and my `wtk
24 overlay`_. Install with::
26 # emerge -av app-portage/layman
28 # emerge -av dev-python/pycomedi
34 If you're installing by hand or packaging pycomedi for another
35 distribution, you'll need the following dependencies:
37 ============ =================== ================ ==============================
38 Package Purpose Debian_ Gentoo_
39 ============ =================== ================ ==============================
40 NumPy_ ? python-numpy dev-python/numpy
41 SciPy_ testing python-scipy sci-libs/scipy
42 Comedi_ Comedilib interface python-comedilib sci-libs/comedilib [#wtk]_
43 nose_ testing python-nose dev-python/nose

48 .. [#wtk] In the `wtk overlay`_.
50 If python-kmod is installed, you will get additional module
51 information from the ``info.py`` demo program. If it is not
52 installed, everything will still work, but ``info.py`` will only be
53 able to get the module version, not the kernel version, staging-ness,
60 Pycomedi is available as a Git_ repository::
62 $ git clone git://tremily.us/pycomedi.git
65 See the homepage_ for details. To install the checkout, run the
68 $ python setup.py install
74 See the examples in the ``doc`` directory.
80 Run integration tests with::
82 $ nosetests --with-doctest --doctest-extension=txt doc
84 The analog integration tests read from analog input channels 0 through
85 3, and write to analog output channels 0 and 1, so you'll need a board
86 with that many channels. You should also make sure that the analog
87 output channels aren't plugged into anything sensetive, since the
88 tests sweep their output around over a reasonable chunk of the channel
89 range. Some of the internal unit tests also write, so it's safest to
90 just disconnect all digital lines and analog outputs before running
93 Run both integration tests and internal unit tests with::
