ffcfstress stress tests constant non-enveloped forces on a force
10
It simulates a moving spring force by applying a frequently updated
11
constant force effect.
13
.B Beware, the stress test may damage your device!
15
At least one option is required.
17
.BR \-d " <\fIdevice\fP>"
18
The device to test (by default \fI/dev/input/event0\fR).
20
.BR \-u " <\fIupdate rate\fP>"
21
The update rate in Hz (25 by default).
23
.BR \-f " <\fIfrequency\fP>"
24
The spring center motion frequency in Hz (0.1 by default).
26
.BR \-a " <\fIamplitude\fP>"
27
The spring center motion amplitude, between 0.0 and 1.0 (1.0 by
30
.BR \-s " <\fIstrength\fP>"
31
The spring strength factor (1.0 by default).
34
Dummy option, useful when all defaults should be used.
36
\fBffmvforce\fP(1), \fBfftest\fP(1), \fBjstest\fP(1).
