Tango backend attempt

[marcelldls]

Fastcs tango backend

• I have made forks of Martin’s demo and fastcs respectively
  • https://github.com/marcelldls/FastCS
  • https://github.com/marcelldls/demo-fast-cs
• Gary has given an initial review and I have included his feedback

You can run the demo by:

• Checking out the tango branches of fastcs and the demo
• Spinning up a tango control system
  • yum install podman-compose
  • podman-compose up from the demo directory
• From the dev container
  • Start the tickit device via the vscode debug launch
  • Start tango device server by running test-demo from the command line

You can interact with the device in the following manners:

• Via an interactive python terminal:
  • Run itango3 from the dev container
  • Create device proxy: dev = DeviceProxy("my/device/name")
  • then you can use auto complete on dev (e.g. dev.get_attribute_list() or dev.RampRate)
• Via Jive GUI database administation application
  • podman pull andygotz/tango-jive:7.19
  • podman run -ti --rm -e DISPLAY=$DISPLAY -e TANGO_HOST=localhost:10000 -v /tmp/.X11-unix:/tmp/.X11-unix --security-opt label=type:container_runtime_t --net=host andygotz/tango-jive:7.19
  • You may first need to run xhost +local:podman to get a window
  • Device interaction via the built in ATKPanel GUI can then be done by right clicking on the device (via the tree) in Jive and selecting monitor device
• Alternatively via a Taurus gui I scraped together (python taurus_gui.py from outside dev container) (Its not programmatic, I just made it out of interest to get something similar to the epics gui – the observatory science team claim Taurus and Taranta are the popular Tango gui frameworks)
