Re: [Discuss-gnuradio] USRP2 - external clock pps python example

[Burak TUYSUZ]

In UHD for the time stamps you suggested to use the cpp interface which is fine and there is also an example.
How can I make sure that external clock is locked properly in cpp.
Thanks in advance

The convenience function sets the positive edge which seems to be every
device out there.

For advanced configuration, see the c++ doxygen, so you can extrapolate
what the equivalent code in python should be.
