libiio is an open source C library developed by Analog Devices for interfacing with Industrial I/O (IIO) devices - ADCs, DACs, IMUs, RF transceivers, temperature sensors, and more. It underpins a broad ecosystem of host-side tools including Scopy, pyadi-iio, and MATLAB, all of which connect to targets over network, serial, or USB transports.

This talk walks through the architecture and practical mechanics of the port. We will cover how libiio's external backend integrates with Zephyr's device model, allowing any driver that implements the IIO device driver API to appear as a first-class IIO device. We will look at built-in bridge drivers that wrap any Zephyr ADC, DAC, or sensor device into an IIO device. We will also cover how the module integrates into the Zephyr build system using Kconfig, device tree, and snippets to enable libiio with minimal changes to an application.

We will demonstrate a Zephyr board being queried from Scopy and pyadi-iio, and close with a look at what is in progress - trigger support for deterministic sampling and streaming, and a USB transport as a complement to the existing UART and network transports.
