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 1941 informs userspace about sensor chip's placement relative to the 1942 main hardware it is mounted on. 1943 1944 Main hardware placement is defined according to the local 1945 reference frame related to the physical quantity the sensor 1946 measures. 1947 1948 Given that the rotation matrix is defined in a board specific 1949 way (platform data and / or device-tree), the main hardware 1950 reference frame definition is left to the implementor's choice 1951 (see below for a magnetometer example). 1952 1953 Applications should apply this rotation matrix to samples so 1954 that when main hardware reference frame is aligned onto local 1955 reference frame, then sensor chip reference frame is also 1956 perfectly aligned with it. 1957 1958 Matrix is a 3x3 unitary matrix and typically looks like 1959 [0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix 1960 [1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware 1961 are perfectly aligned with each other. 1962 1963 For example, a mounting matrix for a magnetometer sensor informs 1964 userspace about sensor chip's ORIENTATION relative to the main 1965 hardware. 1966 1967 More specifically, main hardware orientation is defined with 1968 respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where : 1969 1970 * Y is in the ground plane and positive towards magnetic North ; 1971 * X is in the ground plane, perpendicular to the North axis and 1972 positive towards the East ; 1973 * Z is perpendicular to the ground plane and positive upwards. 1974 1975 An implementor might consider that for a hand-held device, a 1976 'natural' orientation would be 'front facing camera at the top'. 1977 The main hardware reference frame could then be described as : 1978 1979 * Y is in the plane of the screen and is positive towards the 1980 top of the screen ; 1981 * X is in the plane of the screen, perpendicular to Y axis, and 1982 positive towards the right hand side of the screen ; 1983 * Z is perpendicular to the screen plane and positive out of the 1984 screen. 1985 1986 Another example for a quadrotor UAV might be : 1987 1988 * Y is in the plane of the propellers and positive towards the 1989 front-view camera; 1990 * X is in the plane of the propellers, perpendicular to Y axis, 1991 and positive towards the starboard side of the UAV ; 1992 * Z is perpendicular to propellers plane and positive upwards. 1993 1994What: /sys/bus/iio/devices/iio:deviceX/in_electricalconductivity_raw 1995KernelVersion: 4.8 1996Contact: linux-iio@vger.kernel.org 1997Description: 1998 Raw (unscaled no offset etc.) electric conductivity reading. 1999 Units after application of scale and offset are siemens per 2000 meter. 2001 2002What: /sys/bus/iio/devices/iio:deviceX/in_countY_raw 2003KernelVersion: 4.10 2004Contact: linux-iio@vger.kernel.org 2005Description: 2006 This interface is deprecated; please use the Counter subsystem. 2007 2008 Raw counter device counts from channel Y.
