Josh, This is great! Although it goes without saying, I'm assuming users should also need to keep in mind that there's no magic going on here w.r.t. gigE bandwidth (i.e., one U2 running "wide open" can pretty much consume an entire gigE port. Now that you've got 2 U2's sharing a single con

2010-12-13 Thread Josh Blum
Hello list, I would like to announce support for the MIMO cable with UHD. The support is experimental, so its not in the mainline yet, and is only available for USRP2 at the moment. The source for the FPGA code has not yet been pushed but you can get the pre-built images here: http://www.ettus.co

[Discuss-gnuradio] 'make distcheck' in next branch

2010-12-13 Thread Tom Rondeau
The git next branch has recently had some issues with performing a "make distcheck" if you didn't have the UHD libraries installed onto your system. I believe I have just pushed a fix for this. If you've been having trouble performing a distcheck because of this, try it now. Let me know if you're

Hey Tom, Great work implementing the libvolk. I had a chance to take a peek at the implementation, so now I have constructive criticism. :-) I see that the various vector functions are all implemented in headers, and at compile time, a python application generates them into the table look-up-code

[Discuss-gnuradio] using signals in flowgraphs

Hello: I have a USRP2 + WBX running with GNU Radio 3.3.0 on openSUSE 11.2. In my flowgraph, I am trying to create a timer that will call a function periodically, say every 200ms. This function would dynamically change some parameters of my flowgraph, such as the frequency or amplitude of a Sign

Hi, I am a fellow n00b to gnuradio. Just to add to Tom's advice, when I first started I found that the easiest and quickest way to get familiar with gnuradio is with the gnuradio companion (and reading everything you can find on gnuradio...). Try searching the web for "gnuradio tutorials." Some

Looks like these files were not moved from gnuradio/usrp. A symlink in fpga/usrp1 to ../../gnuradio/usrp/firmware seems to do the trick, but it would be nice if one of the repos had everything necessary. On 12/13/2010 12:49 PM, Brett L. Trotter wrote: > `include "../../firmware/include/fpga_regs
