Reading from it 9 returns 0 if led is off and 1 if it is on. Writing 0 to it 10 disables the led, writing 1 enables it. 11 12What: /sys/bus/hid/drivers/wiimote/<dev>/extension 13Date: August 2011 14KernelVersion: 3.2 15Contact: David Herrmann <dh.herrmann@gmail.com> 16Description: This file contains the currently connected and initialized 17 extensions. It can be one of: none, motionp, nunchuck, classic, 18 motionp+nunchuck, motionp+classic 19 motionp is the official Nintendo Motion+ extension, nunchuck is 20 the official Nintendo Nunchuck extension and classic is the 21 Nintendo Classic Controller extension. The motionp extension can 22 be combined with the other two. 23 24 Starting with kernel-version 3.11 Motion Plus hotplugging is 25 supported and if detected, it's no longer reported as static 26 extension. You will get uevent notifications for the motion-plus 27 device then. 28 29What: /sys/bus/hid/drivers/wiimote/<dev>/devtype 30Date: May 2013 31KernelVersion: 3.11 32Contact: David Herrmann <dh.herrmann@gmail.com> 33Description: While a device is initialized by the wiimote driver, we perform 34 a device detection and signal a "change" uevent after it is 35 done. This file shows the detected device type. "pending" means 36 that the detection is still ongoing, "unknown" means, that the 37 device couldn't be detected or loaded. "generic" means, that the 38 device couldn't be detected but supports basic Wii Remote 39 features and can be used. 40 Other strings for each device-type are available and may be 41 added if new device-specific detections are added. 42 Currently supported are: 43 44 ============= ======================================= 45 gen10: First Wii Remote generation 46 gen20: Second Wii Remote Plus generation 47 (builtin MP) 48 balanceboard: Wii Balance Board 49 ============= ======================================= 50 51What: /sys/bus/hid/drivers/wiimote/<dev>/bboard_calib 52Date: May 2013 53KernelVersion: 3.11 54Contact: David Herrmann <dh.herrmann@gmail.com> 55Description: This attribute is only provided if the device was detected as a 56 balance board. It provides a single line with 3 calibration 57 values for all 4 sensors. The values are separated by colons and 58 are each 2 bytes long (encoded as 4 digit hexadecimal value). 59 First, 0kg values for all 4 sensors are written, followed by the 60 17kg values for all 4 sensors and last the 34kg values for all 4 61 sensors. 62 63 Calibration data is already applied by the kernel to all input 64 values but may be used by user-space to perform other 65 transformations. 66 67What: /sys/bus/hid/drivers/wiimote/<dev>/pro_calib 68Date: October 2013 69KernelVersion: 3.13 70Contact: David Herrmann <dh.herrmann@gmail.com> 71Description: This attribute is only provided if the device was detected as a 72 pro-controller. It provides a single line with 4 calibration 73 values for all 4 analog sticks. Format is: "x1:y1 x2:y2". Data 74 is prefixed with a +/-. Each value is a signed 16bit number. 75 Data is encoded as decimal numbers and specifies the offsets of 76 the analog sticks of the pro-controller. 77 78 Calibration data is already applied by the kernel to all input 79 values but may be used by user-space to perform other 80 transformations. 81 82 Calibration data is detected by the kernel during device setup. 83 You can write "scan\n" into this file to re-trigger calibration. 84 You can also write data directly in the form "x1:y1 x2:y2" to 85 set the calibration values manually. 86
