Re: GRC:Suitable Sink required


#1

Thanks, but i dont want to use GUI sink. I want to get an array of
samples which represent the periodogram. So that i can do further
processing on them.

Regards

You should probably start by looking at the existing wx gui sinks, copy
and modify one:

The vector sink is not what you want here.

You can use a file sink to write the samples out to a file, and write
some program to process the file.

Or, you need to create your own block in c++ or python. If c++, the “how
to write a block example” is a good reference. If python, the wxgui
sinks are a good reference (see gr.message_sink and gr.msg_queues to get
data out of the stream and into python).
