[USRP-users] E312 low level access to control AD9361

Hi, all,   I have a E312 device and I just find that the tuning speed of E312 is very slow (\~150ms) for each tuning. Thus I would like to modify the underlying tuning source code in the uhd software architecture.   Here is what I found:   I first create a multi_usrp object: uhd::usrp::mul
