Hello,

I am looking for help in using the filter kernels in python.  In particular, I want to use the filter.kernel.fir_filter_fff.

Is this even possible?  I have poked around quite a bit and have not been able to figure out how to properly import/use the kernels from python.  I hope this question isn’t too vague, I can try to provide more details if needed.

Hi Ben,

The kernels are not exported through to Python. They aren't really designed for that, though I can see them being useful. If you want to experiment with it and let us know how it works for you, you just need to add a '#include "gnuradio/filter/fir_filter.h"' and '%include "gnuradio/filter/fir_filter.h"' to filter_swig.i and rebuild. You can also do this with the fft_filter.h to get that class of filters, too.
