Re: How to set variable number of inputs/outputs in Python OOT modules

[George Edwards]

Hi Gavin,

Thanks for the information!

Does this mean that if I wanted 3 inputs and 5 outputs and all floating point values, then inside the Python code, I simply set 

 in_sig = [numpy.float32]

 out_sign = [numpy.float32]

And, in the yml file I set:

inputs:

-      domain:  stream

       dtype:  float

       multiplicity:  '3'

outputs: 

-        domain:  stream

         dtype:  float

         multiplicity:  '5'

Would this be correct?

Thanks again for your help!

Regards,

George

In 3.7, you would use the <nports> tag, but in 3.8 the trick to setting multiple ins/outs in the YML file, is the keyword "multiplicity". You can see the details of how to configure here:

YAML GRC - GNU Radio

Starting with release 3.8, YAML replaces XML as the file format for GNU Radio Companion. This is triggered by switching from Cheetah to Mako as the templating engine, since Cheetah does not support Python 3.
