This is a summary and conclusion of using a NI6259 with Xenomai/Analogy for
digital data I/O. First of all, many thanks to Alexis whose Analogy branch
really allowed us to succeed! We would just like share the final results of our
implementation with the hope that this might help others.
Hi Alexis,
thanks so much for the new feature! I will try it and report back.
In the last months, I actually did run some comparisons between Comedi and
Analogy, and in all cases found that your Analogy implementation performs
exactly the same as Comedi, actually, for CMD-based streaming, I
Hi Alexis,
here is an observation with CMD-based acquisition that puzzles me. Just to
recall, we use an NI6259 board, using your latest analogy branch of xenomai on
a 2.6.29.5 kernel in Ubuntu 9.10. Our computer is a 32bit Dell Precision with 8
core Xeon processors.

Hi Alexis,
I was wondering whether you could help me with some information about CMD

You might recall from previous emails with you, we are trying to implement high
speed data DIO communication with a NI6259 board. We use the CMD structure to
create a

Hi everybody,
here is a quick first report on an issue that appeared with Xenomai 2.5.5 ---
NOTE: 2.5.4 (and earlier) DOES NOT have this issue.
We run multiple real-time processes, synchronized by semaphores and
interprocess communication using shared memory. All is cleanly implemented

Hi Alexis,
we are making great progress with our work. One issue that came up is
whether it would be possible to add
.stop_src = TRIG_COUNT,
.stop_arg = n,
in the command structure, i.e., that the command
that this method is not supported.

Hi Alexis,
in the Comedi examples
(http://www.comedi.org/download/comedilib-0.8.1.tar.gz, the do_waveform.c
example), they suggest to use a general purpose counter as clocking input
a variety of function calls that I cannot directly map to the
current Analogy functionality.
Or, do you happen to know whether there is another, easier to access, clock
source?

Hi Alexis,
thanks a lot for the clarification. Thus, scan_begin_arg is set to the
digital line that I would like to use as a trigger. The triggering itself has
to happen by flipping the bit on this specific digital line, e.g., using
a4l_sync_dio
as in analogue I/O?

Hi Alexis,
I guess I slowly understand that my clocking signal connected to
scan_begin_arg has to come from an external DIO input, if
scan_bigin_src = TRIG_EXT

anything on my board.
In your cmd_bits.c code, you use the a4l_insn_t insn structure below for
triggering, which is what I have to replace with a4l_sync_dio(), I guess?
