ophyd-tango-demo

Getting started / preparation of the environment

Starting point of what is described is an empty mamba/conda environment

• prepare the mamba/conda env

mamba install --file requirements.txt -c conda-forge

• fetch the git submodule ophyd-async https://github.com/desy-fsec/ophyd-async.git
• install ophyd+bluesky

cd ophyd-async/
git submodule init
git submodule update
pip install -e .
cd ..

• run docker-compose to start the tango db and device servers

docker-compose up -d

run the first demo script

based on ophyd-async/docs/user/examples/tango_scan.py. a modified version of this file is in the root of this repo that uses the tango path available in the docker container.

TANGO_HOST=localhost:10000 python tango_scan.py

Note 1: make sure that the environment variable TANGO_HOST is set so that the python process can connect to the tango db inside the docker container Note 2: it may take a few seconds before the scan starts. ... for the first scan it may even take almost a minute before the scan actually runs.

Resources
