Hi again!
I am trying to make a signal processing block that uses an array of
complex numbers at its input. I was just wondering whether
&input_items can support this.
I was told that the &input_items are simply "plain old data." So if I
cannot pass an array of complex numbers as an input argument, is there
a way to process my input so that I can still get a stream of complex
numbers as input?
Hi,
The "how to write a block" GNU Radio guide is an awesome guide to
understanding this:
http://www.gnu.org/software/gnuradio/doc/howto-write-a-block.html
Then you will understand what "input_items" is... it's not what you were
told :P Whatever "plain old data" might actually be.
The quick answer is that it's a stream of arrays, where there can be a
single stream which is what you want (a single array). But read the
guide to completely understand it.
Aside from that, you don't typically call the work() function yourself.
You connect the blocks and as data is streamed through your flow
graph, the work() function is called on that stream. Read the guide and
you will understand this.
