Commands

-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)

local:

with no address part. This is the default.
