iio_stresstest [ options ] -u <uri>

iio_stresstest is a stress-testing program that can be used to find bugs in Libiio or in the Libiio daemon (IIOD).

-h,  --help

Tells iio_stresstest to display some help, and then quit.

-V,  --version

Prints the version information for this particular copy of iio_stresstest and the version of the libiio library it is using. This is useful for knowing if the version of the library and iio_stresstest 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_stresstest -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.

-a,  --auto

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

-T,  --timeout <arg>

Context timeout in milliseconds. 0 = no timeout (wait forever)

-b,  --buffer-size <arg>

Size of the capture buffer. Default is 256.

-s,  --samples <arg>

Number of samples to capture, 0 = infinite. Default is 0.

-d,  --duration <arg>

Time to wait (in seconds) before stopping all threads

-t,  --threads <arg>

Number of threads to use

-v,  --verbose

Increase verbosity (-vv and -vvv for more)

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