Re: [Discuss-gnuradio] Python block help

[Zach Morris]

That worked to create a general block, but I'm still having some trouble with
implementing the forecast(), consume() and produce() functions. 

The goal of the block is to discard elements in an input vector that are
below a certain threshold, and eventually update some statistics based on
the remaining elements. For a vector of 256 elements, there could be
anywhere between 0 and 256 outputs (the arbitrary ratio you mentioned).

The default forecast function has a 1:1 ratio:

Should I replace "noutput_items" with my "vector_length" parameter, ensuring
that we always get (for example) 256 inputs?

In the general_work function, I think we want to consume the entire input
vector once we figure out which elements are above the threshold:

I'm not sure about the produce function; do I need to tell the system how
many items I produce, or is that covered at the end of general_work:


Thank you kindly,

Zach
