As the reading is of the difference 216 between the two inputs, this should not be applied to the _raw 217 reading by userspace (unlike _offset) and unlike calibbias 218 it does not affect the differential value measured because 219 the effect of _zeropoint cancels out across the two inputs 220 that make up the differential pair. It's purpose is to bring 221 the individual signals, before the differential is measured, 222 within the measurement range of the device. The naming is 223 chosen because if the separate inputs that make the 224 differential pair are drawn on a graph in their 225 _raw units, this is the value that the zero point on the 226 measurement axis represents.

This is a rotation matrix which 1944 informs userspace about sensor chip's placement relative to the 1945 main hardware it is mounted on. 1946 1947 Main hardware placement is defined according to the local 1948 reference frame related to the physical quantity the sensor 1949 measures. 1950 1951 Given that the rotation matrix is defined in a board specific 1952 way (platform data and / or device-tree), the main hardware 1953 reference frame definition is left to the implementor's choice 1954 (see below for a magnetometer example). 1955 1956 Applications should apply this rotation matrix to samples so 1957 that when main hardware reference frame is aligned onto local 1958 reference frame, then sensor chip reference frame is also 1959 perfectly aligned with it. 1960 1961 Matrix is a 3x3 unitary matrix and typically looks like 1962 [0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix 1963 [1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware 1964 are perfectly aligned with each other. 1965 1966 For example, a mounting matrix for a magnetometer sensor informs 1967 userspace about sensor chip's ORIENTATION relative to the main 1968 hardware. 1969 1970 More specifically, main hardware orientation is defined with 1971 respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where : 1972 1973 * Y is in the ground plane and positive towards magnetic North ; 1974 * X is in the ground plane, perpendicular to the North axis and 1975 positive towards the East ; 1976 * Z is perpendicular to the ground plane and positive upwards. 1977 1978 An implementor might consider that for a hand-held device, a 1979 'natural' orientation would be 'front facing camera at the top'. 1980 The main hardware reference frame could then be described as : 1981 1982 * Y is in the plane of the screen and is positive towards the 1983 top of the screen ; 1984 * X is in the plane of the screen, perpendicular to Y axis, and 1985 positive towards the right hand side of the screen ; 1986 * Z is perpendicular to the screen plane and positive out of the 1987 screen. 1988 1989 Another example for a quadrotor UAV might be : 1990 1991 * Y is in the plane of the propellers and positive towards the 1992 front-view camera; 1993 * X is in the plane of the propellers, perpendicular to Y axis, 1994 and positive towards the starboard side of the UAV ; 1995 * Z is perpendicular to propellers plane and positive upwards. 1996 1997What: /sys/bus/iio/devices/iio:deviceX/in_electricalconductivity_raw 1998KernelVersion: 4.8 1999Contact: linux-iio@vger.kernel.org 2000Description: 2001 Raw (unscaled no offset etc.) electric conductivity reading. 2002 Units after application of scale and offset are siemens per 2003 meter. 2004 2005What: /sys/bus/iio/devices/iio:deviceX/in_countY_raw 2006KernelVersion: 4.10 2007Contact: linux-iio@vger.kernel.org 2008Description: 2009 This interface is deprecated; please use the Counter subsystem. 2010 2011 Raw counter device counts from channel Y.
