NAME

       ffcfstress - constant force stress test for force-feedback devices

SYNOPSIS

       ffcfstress [-d <device>] [-u <update rate>] [-f <frequency>] [-a <amplitude>] [-s <strength>] [-o]

DESCRIPTION

       ffcfstress  stress  tests  constant non-enveloped forces on a force feedback device.  It simulates a moving spring force by applying a fre-
       quently updated constant force effect.

       Beware, the stress test may damage your device!

OPTIONS

       At least one option is required.

       -d <device>
	      The device to test (by default /dev/input/event0).

       -u <update rate>
	      The update rate in Hz (25 by default).

       -f <frequency>
	      The spring center motion frequency in Hz (0.1 by default).

       -a <amplitude>
	      The spring center motion amplitude, between 0.0 and 1.0 (1.0 by default).

       -s <strength>
	      The spring strength factor (1.0 by default).

       -o     Dummy option, useful when all defaults should be used.
