iio_attr - list IIO devices, and read/write device attributes
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
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.
- 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'. Specific options for USB include Vendor ID, Product ID
to limit scanning to specific devices 'usb=0456:b673'. vid,pid are
hexadecimal numbers (no prefix needed), "*" (match any for pid
only) If no argument is given, it checks all that are available.
- -h, --help
- Tells iio_attr to display some help, and then quit.
- -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'
If the specified device is not found, a non-zero exit code is
returned.
