Kionis KXTIK-series accelerometer driver
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
|
||
|
|
- compatible : Should be "kionix,kxtj9".
|
||
|
|
- reg : i2c slave address of the device.
|
||
|
|
- interrupt-parent : Parent of interrupt.
|
||
|
|
- interrupts : Accelerometer sample interrupt to indicate new data ready.
|
||
|
|
- vdd-supply : Analog power supply needed to power device.
|
||
|
|
- vio-supply : Digital IO power supply needed for IO and I2C.
|
||
|
|
- kionix,min-interval : Minimal data polling interval in millisecond.
|
||
|
|
- kionix,init-interval : Initial data polling interval in millisecond.
|
||
|
|
- kionix,axis-map-x : Select which data will be X-axis of reading.
|
||
|
|
The sensor measures and reports three axis of
|
||
|
|
data, this property selset which data will be
|
||
|
|
interpretd as X-axis gravity data of phone.
|
||
|
|
e.g. Give "0" to this property means the first
|
||
|
|
measurement data will be used as X-axis data
|
||
|
|
- kionix,axis-map-y : Select which data will be Y-axis of reading.
|
||
|
|
Similar to property above, this property selet
|
||
|
|
Y-axis data.
|
||
|
|
- kionix,axis-map-z : Select which data will be Z-axis of reading.
|
||
|
|
Similar to property above, this property selet
|
||
|
|
Z-axis data.
|
||
|
|
- kionix,g-range : Select initial range of measurement. This define
|
||
|
|
the initial configuration of maxinum
|
||
|
|
measurement range of the sensor.Where 2 is 2G,
|
||
|
|
4 is 4G, 8 is 8G, 2G will be used for any other
|
||
|
|
values.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
|
||
|
|
- kionix,negate-x : Boolean to select negate of X-axis data is
|
||
|
|
required, if this property is defined, X-axis
|
||
|
|
data will be negated.
|
||
|
|
- kionix,negate-y : Boolean to select negate of Y-axis data is
|
||
|
|
required, if this property is defined, Y-axis
|
||
|
|
data will be negated.
|
||
|
|
- kionix,negate-z : Boolean to select negate of Z-axis data is
|
||
|
|
required, if this property is defined, Z-axis
|
||
|
|
data will be negated.
|
||
|
|
- kionix,res-12bit; : Boolean to select output data resolution, if this
|
||
|
|
property is defined, sensor will be configured
|
||
|
|
to output 12 bits of data, otherwise sensor will
|
||
|
|
be configured to output 8 bits data.
