NAMEffcfstress - constant force stress test for force-feedback devices
SYNOPSISffcfstress [-d <device>] [-u <update rate>] [-f <frequency>] [-a <amplitude>] [-s <strength>] [-x <axis>] [-A] [-o]
DESCRIPTIONffcfstress 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!
OPTIONSAt 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]
- switch off auto-centering
- Dummy option, useful when all defaults should be used.
