iio_attr(1)

NAME
iio_attr - list IIO devices, and read/write device attributes

SYNOPSIS
iio_attr [ options ] -d [device] [attr] [value]
iio_attr [ options ] -c [device] [channel] [attr] [value]
iio_attr [ options ] -D [device] [attr] [value]
iio_attr [ options ] -C [attr]
iio_attr -S <arg>
iio_attr -h

DESCRIPTION
iio_attr is a utility for displaying information about local or remote IIO devices. By providing an optional value, iio_attr will attempt to write the new value to the attribute.

COMMANDS

The iio_attr utility has a few main options, which control what the main utility of the application is.

-d, --device-attr
    Read and Write IIO device attributes

-c --channel-attr
    Read and Write IIO channel attributes

-B --buffer-attr
    Read and Write IIO Buffer attributes

-C --context-attr
    Read and Write IIO Context attributes

-D --debug-attr
    Read and Write IIO Debug attributes

-S, --Scan
    Scan for available IIO contexts, optional arg of specific backend(s) 'ip', 'usb' or 'ip:usb'. If no argument is given, it checks all that are availble.

-h, --help
    Tells iio_attr to display some help, and then quit.

OPTIONS

-a, --auto
    Look around for devices (locally, ip, and usb), and if there is only one device found, connect to it.

-u, --uri
    The Uniform Resource Identifier (uri) for connecting to devices, can be one of:

    ip:[address]
        network address, either numeric (192.168.0.1) or network hostname (pluto.local)

    ip: blank, if compiled with zeroconf support, will find an IIO device on network

    usb:[device:port:instance]
        normally returned from iio_info -s or iio_attr -S

    usb:
        blank, if there is only one IIO device plugged into USB, find it, and attach to it.

    serial:[port],[baud],[config]
        serial configuration, serial:/dev/ttyUSB0,115200,8n1 115200 baud, 8 data bits, no partity, one stop bit

    local:
        with no address part

-i, --input-channel
    Filters channels by input channels only

-o, --output-channel
    Filters channels by output channels only

-s, --scan-channel
    Filters channels by scan channels only

-I, --ignore-case
    When pattern matching devices, channels or attributes, ignore case

-g, --generate-code <arg>
    Generate small C or python snippets that emulate what you are doing on the command line. Argument is a file name 'foo.c' or 'foo.py'

RETURN VALUE
If the specified device is not found, a non-zero exit code is returned.
