NAME

6       ffcfstress - constant force stress test for force-feedback devices
7

SYNOPSIS

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

DESCRIPTION

13       ffcfstress stress tests constant non-enveloped forces on a force  feed‐
14       back  device.   It  simulates  a moving spring force by applying a fre‐
15       quently updated constant force effect.
16
17       Beware, the stress test may damage your device!

OPTIONS

20       At least one option is required.
21
22       -d <device>
23              The device to test (by default /dev/input/event0).
24
25       -u <update rate>
26              The update rate in Hz (25 by default).
27
28       -f <frequency>
29              The spring center motion frequency in Hz (0.1 by default).
30
31       -a <amplitude>
32              The spring center motion amplitude, between 0.0 and 1.0 (1.0  by
33              default).
34
35       -s <strength>
36              The spring strength factor (1.0 by default).
37
38       -x <axis>
39              absolute axis to test (default: 0)
40              [0 = X, 1 = Y, 2 = Z, 3 = RX, 4 = RY, 5 = RZ, 6 = WHEEL]
41
42       -A     switch off auto-centering
43
44       -o     Dummy option, useful when all defaults should be used.
