[Discuss-gnuradio] How to call another blocks in custom out-of-tree module

Hi,

 

Can you help me to call gnu-blocks from my own out-of-tree code written in python?

 

For example, from this code (http://gnuradio.org/redmine/projects/gnuradio/wiki/OutOfTreeModules)

1 import numpy 2 from gnuradio import gr 3  4 class square3_ff(gr.sync_block): 5     " Squaring block "  6     def __init__(self): 7         gr.sync_block.__init__( 8             self, 9             name = "square3_ff", 10             in_sig = [numpy.float32], # Input signature: 1 float at a time 11             out_sig = [numpy.float32], # Output signature: 1 float at a time 12         )            Self.my_block = (another block / or hier-block) 13 14     def work(self, input_items, output_items): 15         #output_items[0][:] = input_items[0] * input_items[0] # Only works because numpy.array # I want to call self.my_block here 16         return len(output_items[0])

 

I want to call another gnu-blocks (or another hier-block) in work function.(Line 14~16)

1)     How to connect input item to another block's input

2)     How to connect local array to another block's output

 

Please help me.

Actually I need to make my own sub block.

But I need gnuradio blocks during processing my own block.

 

Bye.
