Is there any code similar to usrp_multi.py to use multiple USRP2's already (or is it unnecessary)? As I understand it, with the USRP2, you either use the MIMO cable, or an external reference to synchronize the clocks - then on the host side you would still need to do the align_on_samplenumbers/deinterleaving, etc. business that usrp_multi.py took care of for the USRP1. If nobody has code available to do this, should I expect any major hurdles in trying to convert the usrp_multi.py for use with the USRP2 (besides converting the source create calls, removing the subdev calls, etc)? If I'm using the MIMO cable, do I need to make any additional settings (e.g. sync_to_pps(True) or similar) to synchronize the master to slave? http://gnuradio.org/trac/wiki/USRP2GenFAQ says the VCXO locks on to the external reference, if one exists - which implies this is also the case for the MIMO cable, just wanted to verify that was true. Looking at test_mimo_tx.cc in the u2-mimo-wip branch I see it is possible to setup one usrp2 interface, and send samples to different channels - is that accessible from python now - or is it still code that's in development? If that's the case, is it possible at all to get synchronized samples out of two usrp2's with a MIMO cable right now with python, or should I be writing something in C++ to do that for me? Perhaps Thanks, Doug
