- What: /sys/bus/hid/drivers/wiimote/<dev>/led4
- Date: July 2011
- KernelVersion: 3.1
- Contact: David Herrmann <dh.herrmann@googlemail.com>
- Description: Make it possible to set/get current led state. Reading from it
- returns 0 if led is off and 1 if it is on. Writing 0 to it
- disables the led, writing 1 enables it.
- What: /sys/bus/hid/drivers/wiimote/<dev>/extension
- Date: August 2011
- KernelVersion: 3.2
- Contact: David Herrmann <dh.herrmann@gmail.com>
- Description: This file contains the currently connected and initialized
- extensions. It can be one of: none, motionp, nunchuck, classic,
- motionp+nunchuck, motionp+classic
- motionp is the official Nintendo Motion+ extension, nunchuck is
- the official Nintendo Nunchuck extension and classic is the
- Nintendo Classic Controller extension. The motionp extension can
- be combined with the other two.
- Starting with kernel-version 3.11 Motion Plus hotplugging is
- supported and if detected, it's no longer reported as static
- extension. You will get uevent notifications for the motion-plus
- device then.
- What: /sys/bus/hid/drivers/wiimote/<dev>/devtype
- Date: May 2013
- KernelVersion: 3.11
- Contact: David Herrmann <dh.herrmann@gmail.com>
- Description: While a device is initialized by the wiimote driver, we perform
- a device detection and signal a "change" uevent after it is
- done. This file shows the detected device type. "pending" means
- that the detection is still ongoing, "unknown" means, that the
- device couldn't be detected or loaded. "generic" means, that the
- device couldn't be detected but supports basic Wii Remote
- features and can be used.
- Other strings for each device-type are available and may be
- added if new device-specific detections are added.
- Currently supported are:
- gen10: First Wii Remote generation
- gen20: Second Wii Remote Plus generation (builtin MP)
- balanceboard: Wii Balance Board
- What: /sys/bus/hid/drivers/wiimote/<dev>/bboard_calib
- Date: May 2013
- KernelVersion: 3.11
- Contact: David Herrmann <dh.herrmann@gmail.com>
- Description: This attribute is only provided if the device was detected as a
- balance board. It provides a single line with 3 calibration
- values for all 4 sensors. The values are separated by colons and
- are each 2 bytes long (encoded as 4 digit hexadecimal value).
- First, 0kg values for all 4 sensors are written, followed by the
- 17kg values for all 4 sensors and last the 34kg values for all 4
- sensors.
- Calibration data is already applied by the kernel to all input
- values but may be used by user-space to perform other
- transformations.
- What: /sys/bus/hid/drivers/wiimote/<dev>/pro_calib
- Date: October 2013
- KernelVersion: 3.13
- Contact: David Herrmann <dh.herrmann@gmail.com>
- Description: This attribute is only provided if the device was detected as a
- pro-controller. It provides a single line with 4 calibration
- values for all 4 analog sticks. Format is: "x1:y1 x2:y2". Data
- is prefixed with a +/-. Each value is a signed 16bit number.
- Data is encoded as decimal numbers and specifies the offsets of
- the analog sticks of the pro-controller.
- Calibration data is already applied by the kernel to all input
- values but may be used by user-space to perform other
- transformations.
- Calibration data is detected by the kernel during device setup.
- You can write "scan\n" into this file to re-trigger calibration.
- You can also write data directly in the form "x1:y1 x2:y2" to
- set the calibration values manually.
