If I understand you correctly, then I need to create another block uhd
self.uhd_usrp_source = uhd.usrp_source ( ",". join (("", "")),
uhd.stream_args ( cpu_format = "fc32", channels =
range (1), ), )
so I created it. But I don’t understand how it work
Hi Ivan - I'll work with you off-list on this topic. If we figure out
something useful, we can report back to the lists here. - MLD

Honestly, I have worked very little with gnuradio and do not quite
understand what it means to transfer a UHD USRP object. If it does not make
it difficult for you to show how it works, I will greatly appreciate it.

Ohh ... nice! I didn't know gr-uhd provided that interface! A quick search
shows it's in GR as of sometime in version 3.7 .. not sure how far back,
but certainly in the current release. Good to know!
Note that this gr-uhd GPIO API is available in Python (via SWIG) as well as
C++ ... BUT: it is not
The following link (GR documentation) shows some UHD GPIO functionality.

Hi Ivan - I'm assuming you mean configure and control a USRP's GPIO via UHD
in GNU Radio?
In theory this should be possible, at least in C++ and of course it
requires that the specific USRP have GPIO ...
I'm not sure if there's a Python GPIO API as of UHD 3.15, but if there is
then that method sh
Hello. Please tell me if it is possible to configure GPIO using gnuradio. I
want to use RFNOC blocks and switch an external device using GPIO
