GNURadio Companion "PAUSE"

Is there a way to make GNURadio pause before recording, and wait for the
user to start things? It takes a few seconds for my flow to start up,
and I
would like to have control over the precise time it starts recording.
For
example, I would run the flow, but the record would wait until I clicked
or
pressed a key.

Hi Paul,
use a valve together with some input widget.

There has been great discussion over how to build a valve system the
last month, you might need to read multiple threads to find the
solution that suits you best.

Greetings,
Marcus

Thanks! Got that working with a valve and a button. However, my flow now
uses Volk machine, again, which doesn’t record my data as well as it was
recording before the valve (and without Volk machine). Any way to keep
it
from doing this?

Paul B. Huter

Again, Volk has nothing to do with it. All that printout means is that
your
flowgraph is now using a block which uses a Volk function for
acceleration.
It has nothing to do with the problem you’re seeing.

How do I resolve this problem, then? Is it an issue with my computing
capability?

Well, this is just guessing in the blue, but:
It might be the computing capability of your computer.
Not necessarily of yourself.

Hi Paul,

couldn’t let that comment sit around long.

Though, if I put two and two togehter, I’d say since you’ve been
asking what error 28 indicates, it has even nothing much to do with
computing capabilities of your computer. Just a shortage of
sufficiently fast storage.
As an complacent linux user, by the way, I’d assume that you’ll be off
as good as with a RAM disk enlarging your filesystem write buffers,
without running into system errors (28). That would most probably
re-introduce overruns, though. But that’s how it is – just get some
RAM, and record not more data than fits in there; or get a fast
storage system that can take the 8 bytes per sample.

Please, try to solve one problem with us at a time, I’m starting to
feel that discuss-gnuradio is doing your dev job.

Greetings, and happy hacking
Marcus
