.SH NAME
ffcfstress \- constant force stress test for force-feedback devices
.SH SYNOPSIS
.B ffcfstress
.RB "[" \-d " <\fIdevice\fP>] [" \-u " <\fIupdate rate\fP>] [" \-f " <\fIfrequency\fP>] [" \-a " <\fIamplitude\fP>] [" \-s " <\fIstrength\fP>] [" \-x " <\fIaxis\fP>] [" \-A "] [" \-o "]"
.SH "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.
.PP
.B Beware, the stress test may damage your device!
.SH OPTIONS
At least one option is required.
.TP
.BR \-d " <\fIdevice\fP>"
The device to test (by default \fI/dev/input/event0\fR).
.TP
.BR \-u " <\fIupdate rate\fP>"
The update rate in Hz (25 by default).
.TP
.BR \-f " <\fIfrequency\fP>"
The spring center motion frequency in Hz (0.1 by default).
.TP
.BR \-a " <\fIamplitude\fP>"
The spring center motion amplitude, between 0.0 and 1.0 (1.0 by
default).
.TP
.BR \-s " <\fIstrength\fP>"
The spring strength factor (1.0 by default).
.TP
.BR \-x " <\fIaxis\fP>"
absolute axis to test (default: 0)
.br
[0 = X, 1 = Y, 2 = Z, 3 = RX, 4 = RY, 5 = RZ, 6 = WHEEL]
.TP
.B \-A
switch off auto-centering
.TP
.B \-o
Dummy option, useful when all defaults should be used.
