I would like to announce that a new sequencing tool is
being developed (and nearly finished
in its first public version) at
Barcelona. Its name is FSQT (Finite State machine Queuing Tool).
solves most of the problems of the current Sequencer and adds far more
and power. A summary of its features is shown below (from a
compilation of William Lupton
SNL wish list and others):
-Permits HIERARCHICAL state machine
-PORTABILITY to be executed in any (supported) host computer (e.g.
-Includes a GRAPHICAL FSM editor with skeleton-code
-Optionally permits several state machines share a single
-It is much EASIER TO DEBUG applications (no intermediate engine
and no multi-tasking used).
-Provides FULL C-LANGUAGE SUPPORT, including
-Allows pre and post-actions to be
-Supports Channel Access put with callback.
-Allows an action
not to reset timers.
I will be giving a presentation at the next EPICS
meeting in Trieste on why we need this tool,
its features in detail and its
current state with a proven example developed in our lab.
information, some documentation and a simple trial application can be found
for those really interested in this subject. We also
have a paper in the ICALEPCS'99.
Although it is still work going on to fully
finish/test FSQT, we have found it very powerful
and easy to use in our test
bench. If you want to try it, please go to the above URL and
see it by
yourself (sorry but the example provided in this address doesn't have
states (yet), we will update it soon; if you want the latest
release please contact me).
