ffcfstress − constant force stress test for force-feedback devices
ffcfstress [−d <device>] [−u <update rate>] [−f <frequency>] [−a <amplitude>] [−s <strength>] [−x <axis>] [−A] [−o]
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!
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]
