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. |
