Since version 0.6.0 the cseabreeze backend is packaged together with the conda package, so it's installed by default. The backend is a very thin wrapper around the SeaBreeze library. It's written in Cython and uses the SeaBreeze 2.0 API ("SeaBreezeAPI.h" instead of "SeaBreezeWrapper.h").
Since the open source SeaBreeze library is developed by Ocean Optics it should work nicely with all listed Spectrometers. All the heavy lifting, like formatting commands for communication with the spectrometer is done in the C/C++ library.
Currently not all funtionality of SeaBreeze is exposed via cseabreeze. If you require some functionality that's available in SeaBreeze but not yet in python-seabreeze, file an issue, or implement it yourself and create a pull-request.
Note that if you want, you can install python-seabreeze without the cseabreeze backend by running:
# Run this in the downloaded repository folder
python setup.py install --without-cseabreezeThe pyseabreeze backend is an implementation of cseabreeze using pyusb. It originated from python-oceanoptics. pyseabreeze does all the heavy lifting in Python. It supports all basic spectrometer features (check this list for what works and what doesn't.)
If you want to use pyseabreeze as the backend, install pyUSB:
# make sure pip --version is >= 8.0.0
pip install pyusbIF WINDOWS ( Force the spectrometer to use a libusb driver via Zadig )
IF OSX ( I recommend installing libusb via homebrew: brew install libusb )
IF LINUX ( It's very likely you already have libusb installed )
PyUSB is only correctly installed, if the following code runs and does not raise an Exception.
import usb.core
usb.core.find()Now you can switch to using the pyseabreeze backend by running:
import seabreeze
seabreeze.use("pyseabreeze")
import seabreeze.spectrometers as sb
