Working on a project with custom RFNoC blocks where I need to use the FP
GPIO. I've searched the mailing lists and seen previously suggested options
like reconnecting fp gpio to the custom block, or generating timed command
packets from my block to send to the radio block. Both those options seem
feasible but what seems to be the most straightforward option is to just
use the uhd api call: set_gpio_attr. Like in this example:
https://files.ettus.com/manual/page_gpio_api.html
I tried instantiating a multi_usrp object in my rfnoc app, but that doesn't
seem like the right path and produces some unexpected results.
I noticed that the radio_ctrl API includes that function but all it does is
> throw uhd::not_implemented_error("set_gpio_attr was not defined for
> this radio");

Is there some other way using the device3/RFNoC api to use the
set_gpio_attr or some similar function to configure the gpio from software?
Or more importantly is it even possible when using RFNoC to use those
software functions?
Thanks,
Ryan Marlow
