summary

gr-iio is now merged into mainline GNU Radio and provides libIIO-backed blocks plus ADI-specialized blocks for devices like the ADALM-PLUTO. It shows concrete tools: io device source/sink, io attribute sync/updater, and URI-based backends (local, USB, network). Demo uses an ADALM-PLUTO loopback and a USB joystick as an IIO ADC to multiply joystick axes with two sine carriers and successfully transmit/receive. Performance: local backend reaches ~60–70 MS/s with large buffers; USB tops ~8–10 MS/s; experiments raise throughput from 24 MB/s to ~82 MB/s using dma-buf ideas.
