Hello

I've found a bug in the logical "Not" block of GRC as built from gr 3.2svn. I haven't found the fix in the change logs of 3.2.x, so here I report.
If it has been fixed in the meanwhile please ignore this mail.

The problem is that the "Not" block comes with 2 inputs and does not accept less than 2 inputs. If one tries to set 1 input, the check complains.
I have worked around by changing the related XML:

$GNURADIO_HOME/share/gnuradio/grc/platforms/python/blocks/gr_not_xx.xml

like this:

35c35
< <value>2</value>
---

<value>1</value>
38c38
< <check>$num_inputs &gt;= 2</check>
---
<check>$num_inputs &gt;= 1</check>

Cheers
Alberto
