pyOceanopticsSpectrometer 0.5rc1

A python library/GUI to access and control OceanOptics spectrometers

pyOceanopticsSpectrometer

pyOceanopticsSpectrometer is a Python library/GUI interface to control several models of spectrometers from Ocean Optics. The package is composed of two parts, a low-level driver to perform basic operations, and high-level GUI, written with PyQt5, which can be easily embedded into other GUIs. It heavily relies on the package python-seabreeze.

The interface can work either as a stand-alone CLI or GUI application, or as a module of ergastirio.

The list of devices supported can be found in the table in the readme file of python-seabreeze, with either the `cseabreeze' or 'pyseabreeze (usb)' backend.

• Installation

Installation

Use the package manager pip to install,

pip install pyOceanopticsSpectrometer

This will install all required libraries, included seabreeze. To finalize the installation of seabreeze, additional steps are required (see also instructions in python-seabreeze):

• Run the command seabreeze_os_setup in any terminal
• Install pip install pyusb
• Install pip install libusb
• If you run into errors when running the application, you might need to manually install libusb1. Go here, Downloads -> Latest Windows Binaries. In the zip file, enter either the folder MinGW64/dll or MinGW32/dll (depending on your OS). Copy the file libusb-1.0.dll into C:\Windows\System32.

The package seabreeze uses two different backends (cseabreeze and pyseabreeze (usb)), and some devices are compatible with only one of them (see table in readme file of python-seabreeze). By default, pyOceanopticsSpectrometer uses the backend pyseabreeze (usb), which is referred to as just pyseabreeze in the code. To change this to cseabreeze, after installation, go to the directory which contains the code of pyOceanopticsSpectrometer, open the file config.json, and change the value of "backend" from pyseabreeze to cseabreeze.
