Pass new types to the "make" function

GNU Radio

hello every body,
I really have a problem with data types when I want to use my
out-of-tree
module in GRC which is written in c++.
I have a “make” like this:

make(unsinged int x, usigned char y)

how could I use this block in GRC?

please help me,

Thank.

Hi Mostafa,

because I hope this will solve your problem as well as make it easier
for me to understand you and vice versa, I’ve generated a minimal
example of what you’re trying to do.
Please clone

and tell me if it reflects what you’re trying to do.
The only files I modified after generation with gr_modtool were

  • lib/try…cc
  • python/qa_try_…py
  • grc/try…xml

Greetings,
Marcus

Hi Marcus,
Thank you for your guides. I clone your files and finally got that I can
pass “unsinged int” to the make but in the xml file I can put the
int !!! That’s I wanted. Thank you again.

But one of my blocks must give an array of “int”:

int g[] = {1,2,3};
…

And the “make” should be like this: *make(int g)
I looked at the block “vector source” which gives a vector for it’s make
function. However, I want to pass an array in GRC form of the block i.e.
xml file!!!
What do you prefer?

greetings,

SWIG automatically generates wrappers for the python tuple type.
Refer the mass of examples of tuples being used as parameters in GRC
blocks for reference :wink:
Again, don’t write anything funky yourself, just use a
std::vector* as parameter to your C++ block.

Greetings,
Marcus
