experiment control

Common setup

0. Create Python 3.6 environment named py36

python-seabreeze does not support Python 3.7 and above

$ conda env create -f environment.yml python=3.6

$ conda activate py36

$ conda install -c anaconda ipython   # this is to make sure that iPython runs from this new environment

or if you already have a Python 3.6 environment you may install the dependencies using this command

$ conda env update --file environment.yml --prune

To update the yaml file to reflect latest packages

$ conda env export > environment.yml

1. Clone Mabuchi lab sources

$ git clone https://github.com/mabuchilab/Instrumental.git
$ git clone https://github.com/mabuchilab/NiceLib.git
$ git clone https://github.com/doddgray/experiment_control.git

2. Install Dependencies

$ pip install pyvisa

or

$ conda install -c conda-forge pyvisa
$ conda install future
$ conda install cffi

# for running measurements inside Instrumental
$ conda install -c conda-forge uncertainties

3. Run setup on each of Mabuchi lab sources

$  python ./NiceLib/setup.py install

$  python ./Instrumental/setup.py install

Setup for Ocean Optics Spectrometer

1. Install seabreeze open source drivers

For Windows

Download installer from https://sourceforge.net/projects/seabreeze/files/SeaBreeze/installers/ and run If a zip file is downloaded, plug in the spectrometer and use the update driver and browse for driver files from the extracted files.

For MacOS

Download from

https://sourceforge.net/projects/seabreeze/

Following the instructions in

https://oceanoptics.com/api/seabreeze/index.html#install_linux

Run the following to compile Seabreeze drivers and set paths

$ make
$ export DYLD_FALLBACK_FRAMEWORK_PATH="$PWD/lib"
$ export DYLD_LIBRARY_PATH="$PWD/lib"

Un plug and replug usb and Run the following to test if Seabreeze drivers are installed

$  test/seabreeze_test_posix

2. Install python-seabreeze

# For Python 3.6 distributions and below
$ conda install -c poehlmann python-seabreeze

# For Python 3.8 and beyond
$ conda install -c poehlmann seabreeze

3. Install pyqtgraph

$ conda install pyqtgraph

http://www.pyqtgraph.org/documentation/installation.html

3. Connect usb to spectrometer and test

$ python ./experiment_control/ocean_optics_HR4000_plot.py

Setup for PyVisa and Keithley 2400 SourceMeter

1. Install PyVisa

Follow instructions at https://pyvisa.readthedocs.io/en/master/getting.html

2. Install NI-VISA backend(drivers etc.)

Download and install NI-VISA http://www.ni.com/en-us/support/downloads/drivers/download.ni-visa.html#305862

Install NI-488.2 for GPIB support http://www.ni.com/en-us/support/downloads/drivers/download.ni-488-2.html#306165

for Mac OSX Allow National Instruments software access to system in System Preferences > Security & Privacy

Check to see if the driver is properly installed In [1]: import visa In [2]: rm = visa.ResourceManager() In [3]: rm.list_resources() Out[3]: ('ASRL1::INSTR', 'GPIB0::15::INSTR')

Updating environment.yml file

$ conda env export > environment.yml
