Hi everyone, I just wanted to inform everyone that we made a significant update to master/next tonight to start using Volk. This merges in my safe_align branch that I mentioned a couple of weeks ago. After verifying that it was working on various platforms, including the E100 (and therefore ARM/NE

A quick question on how the trigger works in UHD. I have some basic code integrated with the help of your suggestions. Burst tagger port 0 is the raw complex sample stream. Burst tagger port 1 is the trigger. Let's say the raw complex sample stream has an outgoing packet. I'm assume that I cha

That makes sense, but what about in a case like MSK? It looks like the GMSK example in gr-digital requires an integer for samples_per_symbol due to the Gaussian pre-filter. In that case, aren't possible data rates limited to those that will result in a USRP sample rate that is supported exactly?

Ben, Yes, I was definitely confused. I think this is promising. So you're saying that it gets populated by Doxygen markup that's already in the files? So we don't have to redo any of the documentation that we already have, right? Also, I've been adding Doxygen pages (.dox files) with more descript
