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.
