HOWTO write hkl to EPICS PVs when motors move #253

Open prjemian opened 1 year ago

prjemian commented 1 year ago

Some users like to keep EPICS PVs with the current h, k, l values for other software to use. The other treats these PVs as read-only, bluesky will not be expected to move the diffractometer (or otherwise act) if the other software changes them.

Show how to do this.

One way is to override the inverse() method, updating the EpicsSignal objects after the pseudos are calculated.
