haptics devices linux driver support

[Trilok Soni]

Hi,

Does anyone know example Linux drivers for haptics devices?

Yup, drivers/misc/phantom.c for Sensable Phantom (the old one over PCI).
The rest needed (esp. floating point computation) is done in userspace.

Then, all force-feedack drivers under drivers/input and drivers/hid.

What exactly do you want to know?

Hi,

There's three types as I know,

1) just GPIO enable motor
2) GPIO & PWM motor.
3) I2C based GPIO & PWM motor.

Frankly we made a motor framework at kernel. but I 'm not sure motor
is right naming or not.
I think we need new framework. since it's not input device.

Thank you,
Kyungmin Park

I am looking at 3rd type, and evaulating that for embedded systems
devices having haptics chips can be programmed under drivers/input or
not. It is kind of early discussion and gathering inputs on what could
be lacking part in input subsystem for support such category of
devices.

Is it possible for you to submit your version of code and drivers? It
will be good starting point for discussion.

Hi,

I am interested to know real examples of haptic devices you speak about.
It would be nice if you send some links or pics.

I remember there was the same problem categorizing other input devices
like accelerometers.

Thanks

Hi, I will post the haptic framework soon(maybe tomorrow) instead of
Kyungmin because he leaves a office for days.

FYI: I already finished the i2c based pwm & gpio devices. but I'm not
sure can release it at this time since we need to review it
internally.

Do you hear any patent issue? Since just one vendor (V company) has
almost patents related with vibrators.

Please find out the these.

Thank you,
Kyungmin Park

Please keep patent talk off lkml.
