Sadly, I seem to be missing something (mentally) still.
So I followed the very nice write up previously recommended here:
and it pretty much makes sense (at least conceptually).
The next step was to combine that knowledge with what I want to do,
create and RFNoC block. To do that I went into my gr-howto OOT folder
gr_modtool add -t sync halving
gr_modtool makexml halving
I set it up to use the defaults, be a C++ project, , not have any
parameters, and not have any QA.
I go into gr-howto/grc and edit howto_halving.xml by getting rid of the
two nports tags and changing the in and out types to be complex (instead
I go to gr-howto/build and run: make clean && make
And that is where I get errors. In order to get make to work right, I
have to go into gr-howto/lib/halving_impl.cc and make some changes so
that it can compile fine.
My confusion is that I feel like those changes are then what the block
is doing, right? Wouldn't I want the block's task to be done in the
verilog code? I am having trouble seeing the mating of RFNoC and the
