Joshua,
Generally Fabien is right. To exercise the full feature set of the
GPIO you would likely need an OOT block. However, if only limited
performance and features are needed then you might get away with using
the Python embedded block or Python snippet in GRC to implement
something quick and easy. This was the route I took to control an
external TX/RX switch. I imagine any low-rate control would be feasible.
Jared.
Since the GPIOs are not really designed for high-speed I/O, then a
Python block would be more than capable of "keeping up".

Hi Joshua,
I'm also using GPIO on LFTX and LFRX on a N210 and I can tell you
that you will not find source or sink that deal with that IO as
far as I know.
The only way to use them is to write an OOT that uses the UHD methods.
Best regards,

For anyone who's familiar with using the USRP3 (specifically the
N310) with GNU Radio:
I'm trying to create a flowgraph in gnu radio companion that
incorporates reading a value from one pin on the front panel GPIO
of the N310 and writing a value to another pin. I'm looking for a
source/sink block for GNU Radio companion that can accomplish
this. Has anyone done this previously, or can anyone point me in
the right direction? I have very little experience with GNU Radio
and have no expertise in programming OOT modules. Thank you for
any help you can provide.
Very respectfully,
