Hi Ignacio,

In the pva2pva module (https://github.com/epics-base/pva2pva) you can find a number of examples, take a look into the iocBoot directory and the example IOCs therein.

The README there could use an update 😉 and I agree that a reference manual would be desirable. The upcoming Code/Document-athon might be an opportunity to get some work done on these.

Cheers,

Timo

Subject: PVaccess | pva2pva/QSRV Resources

Hello everyone!

I'm currently working on an EPICS system that would greatly benefit from using PVAccess, pva2pva/QSRV. The talk, examples and VM used in the EPICS Collab last year have been a great resource so far (thank you Kay Kasemir!!!) and have gotten me far into my prototype.

Moving forward with my work, I was wondering the following:

Are there examples of applications using JSON files within a QSRV implementation. It is mentioned here -> https://docs.epics-controls.org/projects/pva2pva/en/latest/doxygen/qsrv_page.html#qsrv_config but I can't figure out how to actually include the .db in my prototype build.
Is there a PVAccess reference manual (a la CA)? I have been trying to use the protocol specification page in github, but it would be great if there was something covering PVAccess from a higher level perspective.

If anyone has a list of resources that they would be willing to share, it would be very helpful.

Thank you everyone for your help and time.

Saludos,

Ignacio Arriagada @ Gemini Observatory
