hey marcus,
For that block, now i get the following error whenever i execute the
flowgraph in
GRC.
File "/home/abhishek/top_block.py", line 53, in __init__
self.howto_detect_ff_0 = howto.detect_ff(100, 16, 1500)
AttributeError: 'module' object has no attribute 'detect_ff'
>>> Done
Any help will be appreciated,
Thanks in advance,
Abhishek
