Hi all,
A last attempt this time, after struggling already several months with
this subject…
From within my custom (out-of-tree) C++ block I need full control over
USRP sink/source. According to the documentation, the command interface
only implements three functions (gain, center frequency and LO_offset ).
I need much more functionality however (sensors, IQ-imbalance, etc…),
so I looked at another solution.
In my custom block class I added a method that takes 2 pointers:
boost::shared_prt<gr::uhd::usrp_sink>
boost::shared_prt<gr::uhd::usrp_source>
In the Python top_block.py code I add a call to this method in order to
pass the USRP pointers from Python to my C++ custom block.
The pointers seem to be valid in C++, but apparently the corresponding
classes have empty virtual methods, so if I want to use the pointers
nothing happens or Python crashes.
Does anybody know how to get pointers that have all functionality
implemented from the original Ettus library? I am completely stuck… It
may be an ugly hack, but I just need to get things done now.
Regards,
Jeroen
