As the reading is of the difference 204 between the two inputs, this should not be applied to the _raw 205 reading by userspace (unlike _offset) and unlike calibbias 206 it does not affect the differential value measured because 207 the effect of _zeropoint cancels out across the two inputs 208 that make up the differential pair. It's purpose is to bring 209 the individual signals, before the differential is measured, 210 within the measurement range of the device. The naming is 211 chosen because if the separate inputs that make the 212 differential pair are drawn on a graph in their 213 _raw units, this is the value that the zero point on the 214 measurement axis represents. It is expressed with the 215 same scaling as _raw. 216 217What: /sys/bus/iio/devices/iio:deviceX/in_temp_raw 218What: /sys/bus/iio/devices/iio:deviceX/in_tempY_raw 219What: /sys/bus/iio/devices/iio:deviceX/in_temp_x_raw 220What: /sys/bus/iio/devices/iio:deviceX/in_temp_y_raw 221What: /sys/bus/iio/devices/iio:deviceX/in_temp_ambient_raw 222What: /sys/bus/iio/devices/iio:deviceX/in_temp_object_raw 223KernelVersion: 2.6.35 224Contact: linux-iio@vger.kernel.org 225Description: 226 Raw (unscaled no bias removal etc.) temperature measurement. 227 If an axis is specified it generally means that the temperature 228 sensor is associated with one part of a compound device (e.g. 229 a gyroscope axis).

This is a rotation matrix which 1943 informs userspace about sensor chip's placement relative to the 1944 main hardware it is mounted on. 1945 1946 Main hardware placement is defined according to the local 1947 reference frame related to the physical quantity the sensor 1948 measures. 1949 1950 Given that the rotation matrix is defined in a board specific 1951 way (platform data and / or device-tree), the main hardware 1952 reference frame definition is left to the implementor's choice 1953 (see below for a magnetometer example). 1954 1955 Applications should apply this rotation matrix to samples so 1956 that when main hardware reference frame is aligned onto local 1957 reference frame, then sensor chip reference frame is also 1958 perfectly aligned with it. 1959 1960 Matrix is a 3x3 unitary matrix and typically looks like 1961 [0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix 1962 [1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware 1963 are perfectly aligned with each other. 1964 1965 For example, a mounting matrix for a magnetometer sensor informs 1966 userspace about sensor chip's ORIENTATION relative to the main 1967 hardware. 1968 1969 More specifically, main hardware orientation is defined with 1970 respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where : 1971 1972 * Y is in the ground plane and positive towards magnetic North ; 1973 * X is in the ground plane, perpendicular to the North axis and 1974 positive towards the East ; 1975 * Z is perpendicular to the ground plane and positive upwards. 1976 1977 An implementor might consider that for a hand-held device, a 1978 'natural' orientation would be 'front facing camera at the top'. 1979 The main hardware reference frame could then be described as : 1980 1981 * Y is in the plane of the screen and is positive towards the 1982 top of the screen ; 1983 * X is in the plane of the screen, perpendicular to Y axis, and 1984 positive towards the right hand side of the screen ; 1985 * Z is perpendicular to the screen plane and positive out of the 1986 screen. 1987 1988 Another example for a quadrotor UAV might be : 1989 1990 * Y is in the plane of the propellers and positive towards the 1991 front-view camera; 1992 * X is in the plane of the propellers, perpendicular to Y axis, 1993 and positive towards the starboard side of the UAV ; 1994 * Z is perpendicular to propellers plane and positive upwards. 1995 1996What: /sys/bus/iio/devices/iio:deviceX/in_electricalconductivity_raw 1997KernelVersion: 4.8 1998Contact: linux-iio@vger.kernel.org 1999Description: 2000 Raw (unscaled no offset etc.) electric conductivity reading. 2001 Units after application of scale and offset are siemens per 2002 meter. 2003 2004What: /sys/bus/iio/devices/iio:deviceX/in_countY_raw 2005KernelVersion: 4.10 2006Contact: linux-iio@vger.kernel.org 2007Description: 2008 This interface is deprecated; please use the Counter subsystem. 2009 2010 Raw counter device counts from channel Y.
