LibIIO Utilities

NAME¶

iiod - IIO Daemon

SYNOPSIS¶

iiod [ options ]

iiod is a server built on top of Libiio which can share a Libiio context across the network, USB, or a UART link.

-V, --version: Display the version of this program.
-d, --debug: Use alternative (incompatible) debug interface.
-D, --demux: Demux channels directly on the server.
-i, --interactive: Run iiod in the controlling terminal.
-a, --aio: Use asynchronous I/O.
-F, --ffs <arg>: Use the given FunctionFS mountpoint to serve over USB.
-n, --nb-pipes <arg>: Specify the number of USB pipes (ep couples) to use.
-s, --serial <arg>: Run iiod on the specified UART.
-p, --port <arg>: Port to listen on (default = 30431). Using --port 0 will pick an ephemeral port (dynamic / unused in the range between 32768–60999).
-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 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)

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