Dear All,
I want to write ablock where:
The output is the the Inverse of the input,
The output is "1" if there is no input.(It acts like a source)
I am confused how to implement the part where the Block behaves like a Source.
In one mode you need an Input to produce an output (ninput_items_required=1)
and in one mode you need no Input to produce an output (ninput_items_required=0) .
I have looked at the forecast() function where the "relationship between noutput_items and the requirements for each input stream" is defined.
Also I could not figure out how the next block requests samples from the curent block.
Can anybody help?
