gr-iio: Nuances, Advanced Features, and New Stuff
summary
gr-iio is an out‑of‑tree GNU Radio module that uses libiio and iod to stream and control any device with an IIO kernel driver, including ADALM-PLUTO and USRP‑E310, plus hundreds of sensors and gigasample converters. It adds Attribute blocks for register/debug access, a DDS controller, underflow/overflow flags, and filter control. Demo shows FPGA custom IP controlling AD9363 frequency hopping via fastlock profiles on an ADALM‑PLUTO achieving 25 microsecond hops (works but GUI spectrum smears if host cannot keep up).
