NAME

       iiod - IIO Daemon

SYNOPSIS

       iiod [ options ]

DESCRIPTION

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

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.

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