Re: [Discuss-gnuradio] python Hier block using callback

[Marcus Müller]

Hi Themba,

in principle, what you describe sounds right; can you insert some 'print "set_foobar called"'' in the set methods of your hier block, to check whether they are actually being called?

Greetings,
Marcus

Hi all;

I created a python hier block using signal source and a VCO, but  I want to be able to control parameters like amplitude, sensitivity etc il real time using sliders.

I used callback tag on xml together with the set method but it does not work, the parameters does not seem to change at all.

is it possible to achieve what I am trying to do? how can I do it.

your help will be much appreciated.

Regards

Fanatic
