quantum-sensors-tdm

This repo is intended to replace nist_qsp_readout and nist_lab_internals for the purposes of running TDM system under Python 3. Initially, it contained only things that Galen needs to run various systems. Anything you need from the source repos can come in, as long as you test it and works with Python 3 and PyQt5. I also strongly prefer to leave out all GPIB related things, but if you have something that is GPIB but lacks a serial port, we can include that code as well.

Cringe

GUI for setting up the crate and tower. Run as cringe -L from anywhere. Save cringe setup files in ~/cringe_config.

ADR GUi

GUI for homebuilt cryo systems runs automags and a secondary feedback loop that keeps the thermometer temperature from drifting by changing the LS370 setpoint over time. Run as adr_gui from anywhere.

tower_power_gui

GUI for turning on/off the tower power supplies in the right order so it doesn't blow up the power card. Run as tower_power_gui.

tdm_term

Run tdm_term to launch a terminal with named tabs and running dastard, cringe and dastard commander. Requires dastard and dastard commander to be installed. The first time you open roxterm (via tdm_term) go to Preferenes->Edit Current Profile->General and change "When command exists:" to "Restart Command". This seems to cause it to leave the terminal open for new commands.

Before installation, set up venv

Install python3-venv and roxterm. For certain versions of Ubuntu (17.10 and newer), official Debian packages of roxterm are unavaible. An unsupported version of roxterm can be installed by adding the PPA described at https://launchpad.net/~h-realh/+archive/ubuntu/roxterm prior to running the apt install commands.

sudo add-apt-repository ppa:h-realh/roxterm
sudo apt-get update
sudo apt install python3-dev python3-venv roxterm

Then you can copy and paste the entire next block hopefully.

python3 -m venv ~/qsp
source ~/qsp/bin/activate
pip install --upgrade pip
echo "source ~/qsp/bin/activate" >> ~/.bashrc

The echo line adds source ~/qsp/bin/activate to ~/.bashrc, which activates this venv for each new terminal. You may exit this venv with deactivate to run code that requires a different python environment.

Installation

You probably want to install all the stuff you need for TDM, not just this repo, so

pip install -e git+ssh://[email protected]/usnistgov/quantum-sensors-tdm.git#egg=quantumsensorstdm
pip install -e git+ssh://[email protected]/usnistgov/mass.git#egg=mass
pip install -e git+https://[email protected]/usnistgov/dastardcommander#egg=dastardcommander

You may need to enter your github login info. It may go smoother if you set up an ssh key with github so you don't need to enter loging info. If you have a a public ssh key setup, you may be required to add it. If you get an error like Permission denied (public key) you probably have to add your key to github.

Here we install with the -e "editable" flag. On Ubuntu 18 in the venv this causes the code to be installed to qsp/src. On a Mac without a venv I found the code to be installed to src relative to where the command was executed.

You also need to copy sudo cp namedserial/namedserialrc /etc and sudo cp adr_system/adr_system_setup.sample.xml /etc/adr_system_setup.xml and update the entries therein to match your system. There are additonal example files in doc/etcfiles.

You can figure out which of those to remove if you only need some.

Also install the non-Python packages, Dastard and Microscope:

• https://github.com/usnistgov/dastard
• https://github.com/usnistgov/microscope

You also need to install the exodriver (I'm pretty sure) for labjack, see instructions here: https://labjack.com/support/software/installers/exodriver Or try the following:

cd ~/Downloads
sudo apt-get install build-essential libusb-1.0-0-dev install git-core
git clone git://github.com/labjack/exodriver.git
cd exodriver/
sudo ./install.sh
cd ..
rm -r exodriver

On ubuntu 20 use this instead:

sudo apt-get install build-essential libusb-1.0-0-dev  git-core

Documentation

There is very little, but check in the doc folder and you might find some.

Cringe External Commands

• Cringe has a ZMQ Reply (you use as Request) socket listening on port 5509. It accepts the commands;
  • SETUP_CRATE
  • FULL_TUNE
• See tests tests/test_cringe.py for more info on replies.

Development tips

Working on cringe

• Make a /etc/namedserialrc file with dummy rack and dummy crate
• cringe -A 0 1 2 -S 0 1 2 -C DFBCLK DFBx2 BAD16 -T DB1 13 will launch cringe with one of each useful card
• -D flag will turn on debug output
• pytest -s is useful to see all output, pytest-watch will hang due some unknown issue with the zmq_rep tests, so just use pytest
