Description

As a PandA user, I would like to load a panda yaml file after creating my PandA device. Some PV's which are correctly configured during device creation are then overwritten by this yaml file. Since these PV's are configured for us, we never want these saved and loaded

Acceptance criteria

  • save_panda utility function ignores all PV's which start with the string 'DATA'. (Try saving a panda and looking at the yaml output to see these data PV's. ophyd-async's generic save function accepts a list of signals to ignore.

Contributor guide

Research direction
Inspect the save panda utility function and modify it to ignore PVs starting with 'DATA' by passing a list of signals to ignore, as the ophyd async generic save function accepts such a list.
