Re: Integration of python's time.time() and work() calls

GNU Radio

Or is there a way to make sure that the in-buffer gets updated multiple
times within the same work call?

Will placing the work function inside a while 1 do the trick? But I
guess
the issue with that is, as long as data is available, the scheduler
calls
work function again and again anyway.

I’m still a little muddled up about this. I have read a lot of the posts
on
the forum and the tutorials on the website as well.

Thanks for your time

Never do that. Your job as GR user is to write the work() function. GNU
Radio will call it, whenever data is available. You can’t make data
appear faster than it appears, and you can rely on GR to call your
work() as soon as possible. Just don’t worry about doing this yourself.

Write your work() function in a manner that consumes as many items as it
can whenever it’s called, and return exactly that number. GNU Radio will
take care of the rest :slight_smile:

Indeed!

GNU Radio’s primary job is to keep things simple for you: it allows
developers to just write their algorithms inside a work function. All
they have to do is take the input they get, generate the output they
want, and tell GNU Radio how much has been done.
