Subject: | [Discuss-gnuradio] OOT sourcec block in python error |
Date: | Mon, 30 Jul 2018 17:22:35 +0000 |
Hi, I am trying to build a source block in python. Below is my code. After using the block I am getting a syntax error: self.Span_SourceBlock_0 = Template error: Span.SourceBlock($input) My block should take input from user(int/float), and output the same. Though these are available blocks in GnuRadio but I am trying to learn on building it. Can you please check if my way of writing the code is correct? import numpy from gnuradio import gr class SourceBlock(gr.sync_block): """ docstring for block SourceBlock """ def __init__(self, input): self.input = input gr.sync_block.__init__(self, name="SourceBlock", in_sig=None, out_sig=[numpy.float32]) def work(self, input_items, output_items): out = output_items[0] out[0][:] = self.input return len(output_items[0]) Thanks, Ayaz |
