Thanks for your reply.
Actually I need the
human triggered function in GnuRadio but I just do not know
how to do that… thanks for your help.
If you took Gnu Radio and radios out of the picture, and the
question was "how do I trigger something to happen when I press a
certain key on the
keyboard, or press a button of some sort?" is solving THAT problem
something that is easy for you? If the answer is a decided NO, then
you may need to gain more experience in general software design
FIRST before wandering into the abstruse disciplines of signal
processing
and radios.
if the answer is instead "not a problem, I already know how to do
that", then I suggest that you spend some time with the Gnu Radio
tutorials.
it should come as no surprise that Gnu Radio, being what amounts
to just a specialized programming environment, hasn't necessarily
already
come up with everything you might want to do in a nice tidy
package. Some programming will be required.
From your e-mail address I assume that you're a student. it may not
have occurred to you this early in your software career that the set
"useful things someone might want to do with a computer" and
"useful things someone might want to do with radios" are very very
large
(if not infinite) sets. Which means that from a practical
perspective "some programming will likely be required" is almost
always the answer.
I've cross-posted to discuss-gnuradio because there may be an
audience there who have already done something similar to what you
want and
may ask more clarifying questions.
It depends on what sort of latency you need in
the trigger. Given that it is human triggered I’m guessing
fairly sloppy.
If it could be a keyboard key and you don’t
need microsecond scale latency, then this is all doable in
software/GnuRadio and you should probably post your
question on the discuss-gnuradio mailing list since an
implementation of this would be largely independent of
radio hardware.
Hello everyone.
I am using USRP
N210 and Gnuradio 3.7. I want a
“trigger” like a button that only when I push the
button then the USRP start to transmit the sample from
file source. I did not find any materials or
experience from other about this case.
The reason I want
to do this is that the transmission is correlated to
the human motion so I need to control the timing.
Is there anyone
know how to implement this fuction?
Regards,
Kevin
