Re: [Discuss-gnuradio] Using GRC generated python code inside a C++ code

Hi Sebastian,

Thanks for your reply. In the meanwhile I was going through some documents on embedding Python in C++. I liked the idea of having a python code embedded in my client c++ code. But I think access data variables from the gnuradio code (for eg centre freq, bw, gain, etc) will be difficult. Because I want to set them from my client c++ code. I am still searching for other options, but so far python embedding seems good. Will let you know how it works.

If others have any other options, please let me know.

Thanks!

Pranav

Well, there a number of options. Given your description its hard to say which one is best.
Aside from maintainability and flexibility of the system, it really depends on the required interaction between the components.
You could
    - re-implement the fg in C++.
    - create Python bindings for your C++ client (e.g. with swig) and do the integration/coupling in Python (outside of the fg)
    - embed Python in your C++ client (https://docs.python.org/2/extending/embedding.html)
    - simply run the Python interpreter as a sub-process if the C++ client

If you choose 2, 3 or anything not the list let me know how it worked out =)

Hello,

I have a GRC generated python code. I also wrote a server-client code in C++. I want to implement the client-code along with the GNU python code. The essence is that I want to a run a client C++ code, which will call the python code in a thread and start the USRP to receive/transmit data, and continue performing it's own process in another thread. I am not sure how I could go about this. I also considered implementing the client C++ code as module in GNU radio and use it in the flow graph. But I think that's not how a client background code should run.

Any thoughts on this matter would be helpful. Thanks in advance.
