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 fre- quently 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] -A switch off auto-centering -o Dummy option, useful when all defaults should be used.
ffmvforce(1), fftest(1), jstest(1).
