ffcfstress: constant force stress test for force-feedback devices

NAME

ffcfstress - constant force stress test for force-feedback devices

SYNOPSIS

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

DESCRIPTION

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.
