ffcfstress1
Constant force stress test for force-feedback devices
Usage
ffcfstress [-d
<device>]
[-u
<update
rate>]
[-f
<frequency>]
[-a
<amplitude>]
[-s
<strength>]
[-x
<axis>]
[-A]
[-o]
Overview
ffcfstress stress tests constant non-enveloped forces on a force feedback device. It simulates a moving spring force by applying a frequently 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).
-
-x <axis> -
absolute axis to test (default: 0)
[0 = X, 1 = Y, 2 = Z, 3 = RX, 4 = RY, 5 = RZ, 6 = WHEEL]
-
-A -
switch off auto-centering
-
-o -
Dummy option, useful when all defaults should be used.
