Hi all, Since GPIO support for RFNoC blocks has been requested so often, and by so many people, it deserves its own email.
With the latest push of commits onto our master branch, we now have support for connecting your RFNoC blocks to front-panel GPIOs on *all* of our RFNoC devices (so including the often requested X310, the recently requested N310, but also all the other devices, i.e. X410/X440/E320). If you're interested in the details, see this and the following commits: https://github.com/EttusResearch/uhd/commit/789301bde1c612a09290a54a4d36ff8962b36dfa. In a nutshell, RFNoC blocks can be connected to the front panel through regular IO ports. All the RFNoC tooling will make it reasonably simple to build blocks that require access to GPIOs. You can even select which GPIO pins are driven by your RFNoC block, and which pins are driven by the radio (so you don't lose any features this way). We will be also providing an example in the rfnoc-oot-blocks repository, but that is not quite ship-shape yet. Keep your eyes on that repo ( https://github.com/EttusResearch/rfnoc-oot-blocks). We just want to give you usrp-users subscribers a heads-up! Thanks to all the folks who provided feedback on this feature! --Martin and the UHD team
