Re: Problem with adjusting value during runtime in my OOT block

[Josh Morman]

Those files look good to me - I'm wondering how the python bindings look.
Can you share the file python/bindings/adding_ff_python.cc ?

adding_ff_python.cc looks like that - https://pastebin.com/nmpshmvj

Yes, that is the problem - not sure why modtool bind is not doing the
trick.  You can manually add the method if you want, which would just look
like:

.def(py::init(&adding_ff::make),
py::arg("constant0"),
D(adding_ff,make)
)
.def("set_constant0", &adding_ff::set_constant0)
;

The only thing then to be careful of is if you run modtool bind again, it
would blow away your changes

It may be worth trying to figure out why modtool bind is not doing the full
set of methods that pygccxml would find, such as trying a new oot from
scratch and see if the same problem exists, now that pygccxml is installed

Python problem..

[tech k1ng]

Hi there,

This is my first mailing post, so please excuse me if there are any errors.

I'm trying to make a block that gives me the bins with corresponding its
energy ([bins, energy]) when over a thresh, so input vector is from "log
power fft" block. With the output, I'm hoping to store it as a file for
further use, or perhaps use it to visualize it. Marcus Müller has already
proposed something similar while describing a technique to another person:
here



The python code is shown here: The output does not seem to represent it
properly. I'm lost right now, and I'm not sure how to proceed. I've
attempted to troubleshoot it and experiment with other things before coming
here to ask for help.

Thank you; I'm hoping that someone can check into this and give me some
advice on what I can do.

Best Regards,
David
