iio_info

iio_info - list IIO devices and device attributes

SYNOPSIS

iio_info [ options ] -u <uri>

DESCRIPTION

iio_info is a utility for displaying information about local or remote IIO devices

OPTIONS

-h, –help

Tells iio_info to display some help, and then quit.

-V, –version

Prints the version information for this particular copy of iio_info and the version of the libiio library it is using. This is useful for knowing if the version of the library and iio_info on your system are up to date. This is also useful when reporting bugs.

-S, –scan [backends]

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.

-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

ip:

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

usb:[device:port:instance]

normally returned from iio_info -S

serial:[port],[baud],[settings]

which are controlled, and need to match the iiod (or tinyiiod) on the other end of the serial port.

[port]

is something like ‘/dev/ttyUSB0’ on Linux, and ‘COM4’ on Windows.

[baud]

is normally one of 110, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200 [default], 128000 or 256000, but can vary system to system.

[settings]

would normally be configured as ‘8n1’ this is controlled by:

data_bits:: (5, 6, 7, 8 [default], or 9)
parity_bits:: (‘n’ none [default], ‘o’ odd, ‘e’ even, ‘m’ mark, or ‘s’ space)
stop_bits:: (1 [default, or 2)
flow_control:: (‘0’ none [default], ‘x’ Xon Xoff, ‘r’ RTSCTS, or ‘d’ DTRDSR)

local:

with no address part.

-T, –timeout <arg>

Context timeout in milliseconds. 0 = use backend default, -1 = wait forever, ‘nb’ or ‘nonblocking’ = non-blocking mode. Default is 0.

-a, –auto

Scan for available contexts and if only one is available use it.

-d, –read-debug-attr

Read and print the value of debug attributes.

-n, –no-read-attr

Do not read or print the value of regular attributes.

RETURN VALUE

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