Receiving USRP bits in c++ (no blocks needed)

Does anyone have an example application that grabs data from the USRP
(say Basic RX) and is entirely in c++? I don’t need GR blocks, just the
bits please.

Thanks,

Chris

It’s called usrp_rx_cfile.py

Thanks, but I’m looking for a c++ app.

Actually, I’d be very interested in this as well. Especially if it
worked under Windoze. Something that will just configure and grab data
from the USRP into a buffer would be fantastic.

Any ideas anyone?

Support for C++ apps with no python is slated for the 3.2 release.

Until then, you’re on your own…

Currently marked as a work in progress for the no-python component in
trac:
http://www.gnuradio.org/trac/query?status=new&status=assigned&status=reopened&component=no-python&order=priority

Johnathan can probably explain what needs to happen to be able to do
this, but the functionality in a release build has yet to be made.

If you’re still interested, I’m about to upload a pure C++
Oscilloscope that I wrote to Sourceforge that does exactly what you’re
looking for, for the Basic TX and RX daughterboards only.

It’s pretty straightforward. The only problem you’ll have is that
with other daughterboards, you’ll have to do more to tune them than
simply setting the center frequency, and the code to do that is only
accessible by Python, as far as I know.

Tuning each daughterboard requires specific knowledge of the hardware.
I’d hold off on trying to implement that until the 3.2 release, as
others have mentioned.

Code to follow shortly.

Ian,

I would love to have this!! Greg H. put a C++ DBSRX driver on the
patches mailing list which I will incorporate into whatever you have.
