Hi Dirk,

Answer two: We are working on a solution to use the data buffer of the timing system for real-time communication. We will need such a fast channel for our FEL. At the moment, the data flow is only one way. We hope that "upstream" communication will be possible soon (depending how busy Jukka is).

The upstream communication is already available for CompactPCI/PXI modules and PMC, but I guess you want it for VME. Actually I have the firmware built for VME, too, but I have not yet found time to test it.


Another bigger issue is that there have been a major changes in the register map and the the EPICS drivers need to be rewritten to support the new 'modular register mapping'. There have also been discussions of getting rid of the eg and er records and implement the new drivers using asyn.
