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 sim-
ulates 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.
The device to test (by default /dev/input/event0).
-u <update rate>
The update rate in Hz (25 by default).
The spring center motion frequency in Hz (0.1 by default).
The spring center motion amplitude, between 0.0 and 1.0 (1.0 by default).
The spring strength factor (1.0 by default).
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.
ffmvforce(1), fftest(1), jstest(1).
