Re: [Discuss-gnuradio] Work on USRP source and sink stream tagging for gr-uhd

[Josh Blum]

Added an example C++ app to demonstrate source and sink tagging:

http://gnuradio.org/cgit/jblum.git/tree/gr-uhd/examples?h=uhd_features&id=ddfddc5c20e2ee4f9a12796100089c203aa4ef27

gr-uhd/examples/tags_demo --help
UHD Tags Demo Allowed options:
  --help                             help message
  --addr arg                         the device address in string format
  --rate arg (=1000000)              the sample rate in samples per second
  --freq arg (=10000000)             the center frequency in Hz
  --burst arg (=0.10000000000000001) the duration of each burst in seconds
  --idle arg (=0.050000000000000003) idle time between bursts in seconds

The tags sink demo block will print USRP source time stamps.
The tags source demo block will send bursts to the USRP sink.
Look at the USRP output on a scope to see the timed bursts.
