Thanks for all the replies. I’m going to start with a Python block and see if I can get it to do what I need it to do, and if not I’ll bite the bullet and try to write an OOT module.

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.

The only way to use them is to write an OOT that uses the UHD methods. Best regards, Fabien, F4CTZ ---- White, Joshua J a écrit ---- (Cross-posted on usrp-users and discuss-gnuradio) 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.
