Tools for controlling piezoelectric actuators.

Pypiezo

Pypiezo is a Python module to control piezoelectric actuators. It is mostly a set of convenient wrappers around pycomedi calls for keeping track of the relevant calibration constants. To get a feel for an “official” set of calibration constants, you can take a peek at veeco_header, which is the beginning of a saved Veeco NanoScope image file. It lists the parameters used by the NanoScope during imaging.

Installation

Packages

Gentoo

I’ve packaged pypiezo for Gentoo. You need layman and my wtk overlay. Install with:

# emerge -av app-portage/layman
# layman --add wtk
# emerge -av sci-libs/pypiezo

Dependencies

If you’re installing by hand or packaging pypiezo for another distribution, you’ll need the following dependencies:

Package	Debian	Gentoo
Numpy	python-numpy	dev-python/numpy
Scipy	python-scipy	sci-libs/scipy
Matplotlib	python-matplotlib	dev-python/matplotlib
H5config		dev-python/h5config [1]
