LibIIO.jl

Build Status Build Status

LibIIO.jl provides Julia bindings for libiio which is a library for interfacing with Linux industrial I/O devices. This packages is meant to give you an easy-to-use high-level API interface matching the Python-bindings with some adaptions to Julia-specifics. If you prefer to work directly with libiio, all C-functions are exposed (but not exported) as a Julia function matching the C functions exactly in name. These function mostly match their C-counterparts but have some added convenience around them and convert their results to Julia types where applicable.

Installation

Install the package using:

] add LibIIO

Example

The package prints information about the objects in the same fashion as iio_info does. For example, if you have the IIO Demo installed, you can connect to the IIO network context using:

using LibIIO

# Adjust to your settings
uri = "ip:127.0.0.1"

# Connect to the context using the network backend.
ctx = Context(uri)

This will print (note, that the trigger errors are correct here!):

IIO context created with network backend.

Similar packages

The AdalmPluto.jl package is focussed on just interfacing an AdalmPluto but actually has a quite complete libiio implementation in its internals. Actually this package uses their libiio_jll package (Kudos for that!) to provide the C binaries. However, that package is not focussed on exposing the libiio API and only gives low-level access.
