CaChannel - EPICS Channel Access in Python

CaChannel is a Python interface to Channel Access. It was developed in 2000 by Geoff Savage using caPython extension In 2008 version 2.x gets re-implemented based on PythonCA extension from Noboru Yamamoto.

In version 3, the CaChannel.ca module was rewritten from scratch using Python/C API. It has the same API as caffi. Because of that, the CaChannel interface can also use caffi.ca by setting environment variable CACHANNEL_BACKEND=caffi. This is also the fallback backend if no EPICS installation exists or the C extension fails to import.
