Hi,
I've just spent a couple of weeks at SSRF working pretty much on this
sort of problem. We were studying the various ways of interfacing a
serial device to EPICS. The device in question was an E-621 piezo
controller manufactured by PI. I made a sort of blow-by-blow account
of what we were doing as we did it. To avoid loading tech-talk with
the text of that document, I've put it on the web. It's at:
 http://www.maden.ch/SSRFnotes/epicsBuildNotesSSRF.html
should anyone be interested.
Regards, David
PS. For those in the EPICS community, who might have me on their email
address book, please note that I retired from PSI this last summer.
This email is from my new email address.

Subject: Generating an IOC with SEQ logic in it.
OK, oh gurus of the EPICS fantastic....
As I understand things, I need to generate an IOC for my system that
contains the sequencer program I wrote to perform some control on one of
our systems.
I have the sequencer program written, and it operates correctly.
When I generated the sequencer program, I installed it inside the
directory that contains all the other components of the system (in my
case, it's </usr/local/EPICS>, and the sequencer source is in
</usr/local/EPICSSRC/modules/soft/seq/seq> ).
I'm having problems understanding how to create the IOC program with
the sequencer component included.
When I try to generate the IOC, I get the message "don't know how to
generate <filename>.o"
I assume I don't have the right configure files included somewhere.
Any suggestions?
Also, I frequently get a message "... too many open files" when I
attempt to make the system.
Any ideas?
David
