PVI

PVI (PV Interface) is a framework for specifying the interface to an EPICS driver. PVI can be used either as a library or an application. PVI Devices can be defined either in code or a YAML file. It can be used to generate UIs (adl, edl, bob) or a template appending info tags to existing records to define an NTTable of the PVs in an IOC.
