As the reading is of the difference 205 between the two inputs, this should not be applied to the _raw 206 reading by userspace (unlike _offset) and unlike calibbias 207 it does not affect the differential value measured because 208 the effect of _zeropoint cancels out across the two inputs 209 that make up the differential pair. It's purpose is to bring 210 the individual signals, before the differential is measured, 211 within the measurement range of the device. The naming is 212 chosen because if the separate inputs that make the 213 differential pair are drawn on a graph in their 214 _raw units, this is the value that the zero point on the 215 measurement axis represents. It is expressed with the 216 same scaling as _raw. 217 218What: /sys/bus/iio/devices/iio:deviceX/in_temp_raw 219What: /sys/bus/iio/devices/iio:deviceX/in_tempY_raw 220What: /sys/bus/iio/devices/iio:deviceX/in_temp_x_raw 221What: /sys/bus/iio/devices/iio:deviceX/in_temp_y_raw 222What: /sys/bus/iio/devices/iio:deviceX/in_temp_ambient_raw 223What: /sys/bus/iio/devices/iio:deviceX/in_temp_object_raw 224KernelVersion: 2.6.35 225Contact: linux-iio@vger.kernel.org 226Description: 227 Raw (unscaled no bias removal etc.) temperature measurement. 228 If an axis is specified it generally means that the temperature 229 sensor is associated with one part of a compound device (e.g. 230 a gyroscope axis).

This is a rotation matrix which 1946 informs userspace about sensor chip's placement relative to the 1947 main hardware it is mounted on. 1948 1949 Main hardware placement is defined according to the local 1950 reference frame related to the physical quantity the sensor 1951 measures. 1952 1953 Given that the rotation matrix is defined in a board specific 1954 way (platform data and / or device-tree), the main hardware 1955 reference frame definition is left to the implementor's choice 1956 (see below for a magnetometer example). 1957 1958 Applications should apply this rotation matrix to samples so 1959 that when main hardware reference frame is aligned onto local 1960 reference frame, then sensor chip reference frame is also 1961 perfectly aligned with it. 1962 1963 Matrix is a 3x3 unitary matrix and typically looks like 1964 [0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix 1965 [1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware 1966 are perfectly aligned with each other. 1967 1968 For example, a mounting matrix for a magnetometer sensor informs 1969 userspace about sensor chip's ORIENTATION relative to the main 1970 hardware. 1971 1972 More specifically, main hardware orientation is defined with 1973 respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where : 1974 1975 * Y is in the ground plane and positive towards magnetic North ; 1976 * X is in the ground plane, perpendicular to the North axis and 1977 positive towards the East ; 1978 * Z is perpendicular to the ground plane and positive upwards. 1979 1980 An implementor might consider that for a hand-held device, a 1981 'natural' orientation would be 'front facing camera at the top'. 1982 The main hardware reference frame could then be described as : 1983 1984 * Y is in the plane of the screen and is positive towards the 1985 top of the screen ; 1986 * X is in the plane of the screen, perpendicular to Y axis, and 1987 positive towards the right hand side of the screen ; 1988 * Z is perpendicular to the screen plane and positive out of the 1989 screen. 1990 1991 Another example for a quadrotor UAV might be : 1992 1993 * Y is in the plane of the propellers and positive towards the 1994 front-view camera; 1995 * X is in the plane of the propellers, perpendicular to Y axis, 1996 and positive towards the starboard side of the UAV ; 1997 * Z is perpendicular to propellers plane and positive upwards. 1998 1999What: /sys/bus/iio/devices/iio:deviceX/in_electricalconductivity_raw 2000KernelVersion: 4.8 2001Contact: linux-iio@vger.kernel.org 2002Description: 2003 Raw (unscaled no offset etc.) electric conductivity reading. 2004 Units after application of scale and offset are siemens per 2005 meter. 2006 2007What: /sys/bus/iio/devices/iio:deviceX/in_countY_raw 2008KernelVersion: 4.10 2009Contact: linux-iio@vger.kernel.org 2010Description: 2011 This interface is deprecated; please use the Counter subsystem. 2012 2013 Raw counter device counts from channel Y.
