Hmm. Seems I tried wrong device. But no vibrations with the right
device, either:
root@duo:/sys/class/leds/0003:054C:03D5.0002:global# echo 4 | fftest
/dev/input/event8
Force feedback test program.
HOLD FIRMLY YOUR WHEEL OR JOYSTICK TO PREVENT DAMAGES
Device /dev/input/event8 opened
Features:
* Absolute axes: X, Y, Z, RZ, Misc ,
[27 00 00 00 00 FF FF 7F ]
* Relative axes:
[00 00 ]
* Force feedback effects types: Periodic, Rumble, Gain,
Force feedback periodic effects: Square, Triangle,
Sine,
[00 00 00 00 00 00 00 00 00 00 03 07 01 00 00 00
]
* Number of simultaneous effects: 16
Setting master gain to 75% ... OK
Uploading effect #0 (Periodic sinusoidal) ... OK (id 0)
Uploading effect #1 (Constant) ... Error: Invalid argument
Uploading effect #2 (Spring) ... Error: Invalid argument
Uploading effect #3 (Damper) ... Error: Invalid argument
Uploading effect #4 (Strong rumble, with heavy motor) ... OK (id 1)
Uploading effect #5 (Weak rumble, with light motor) ... OK (id 2)
Enter effect number, -1 to exit
Now Playing: Strong Rumble
Enter effect number, -1 to exit
Read error
Stopping effects
root@duo:/sys/class/leds/0003:054C:03D5.0002:global#
If it has just one motor, should it say so in the description? Not
advertising both heavy and light motor.
If I do this, I can control vibrations using the "red" led. Value of
70 is lowest that produces anything...
Best regards,
Pavel
