As the reading is of the difference 221 between the two inputs, this should not be applied to the _raw 222 reading by userspace (unlike _offset) and unlike calibbias 223 it does not affect the differential value measured because 224 the effect of _zeropoint cancels out across the two inputs 225 that make up the differential pair. It's purpose is to bring 226 the individual signals, before the differential is measured, 227 within the measurement range of the device. The naming is 228 chosen because if the separate inputs that make the 229 differential pair are drawn on a graph in their 230 _raw units, this is the value that the zero point on the 231 measurement axis represents.

Some devices put their data in the middle 1523 of the transferred elements with additional information on both 1524 sides. Note that some devices will have additional information in 1525 the unused bits, so to get a clean value the bits value must be 1526 used to mask the buffer output value appropriately. The storagebits 1527 value also specifies the data alignment. So s48/64>>2 will be a 1528 signed 48 bit integer stored in a 64 bit location aligned to a 64 1529 bit boundary.

This is a rotation matrix which 1992 informs userspace about sensor chip's placement relative to the 1993 main hardware it is mounted on. 1994 1995 Main hardware placement is defined according to the local 1996 reference frame related to the physical quantity the sensor 1997 measures. 1998 1999 Given that the rotation matrix is defined in a board specific 2000 way (platform data and / or device-tree), the main hardware 2001 reference frame definition is left to the implementor's choice 2002 (see below for a magnetometer example). 2003 2004 Applications should apply this rotation matrix to samples so 2005 that when main hardware reference frame is aligned onto local 2006 reference frame, then sensor chip reference frame is also 2007 perfectly aligned with it. 2008 2009 Matrix is a 3x3 unitary matrix and typically looks like 2010 [0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix 2011 [1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware 2012 are perfectly aligned with each other. 2013 2014 For example, a mounting matrix for a magnetometer sensor informs 2015 userspace about sensor chip's ORIENTATION relative to the main 2016 hardware. 2017 2018 More specifically, main hardware orientation is defined with 2019 respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where : 2020 2021 * Y is in the ground plane and positive towards magnetic North ; 2022 * X is in the ground plane, perpendicular to the North axis and 2023 positive towards the East ; 2024 * Z is perpendicular to the ground plane and positive upwards. 2025 2026 An implementor might consider that for a hand-held device, a 2027 'natural' orientation would be 'front facing camera at the top'. 2028 The main hardware reference frame could then be described as : 2029 2030 * Y is in the plane of the screen and is positive towards the 2031 top of the screen ; 2032 * X is in the plane of the screen, perpendicular to Y axis, and 2033 positive towards the right hand side of the screen ; 2034 * Z is perpendicular to the screen plane and positive out of the 2035 screen. 2036 2037 Another example for a quadrotor UAV might be : 2038 2039 * Y is in the plane of the propellers and positive towards the 2040 front-view camera; 2041 * X is in the plane of the propellers, perpendicular to Y axis, 2042 and positive towards the starboard side of the UAV ; 2043 * Z is perpendicular to propellers plane and positive upwards. 2044 2045What: /sys/bus/iio/devices/iio:deviceX/in_electricalconductivity_raw 2046KernelVersion: 4.8 2047Contact: linux-iio@vger.kernel.org 2048Description: 2049 Raw (unscaled no offset etc.) electric conductivity reading. 2050 Units after application of scale and offset are siemens per 2051 meter. 2052 2053What: /sys/bus/iio/devices/iio:deviceX/in_countY_raw 2054KernelVersion: 4.10 2055Contact: linux-iio@vger.kernel.org 2056Description: 2057 This interface is deprecated; please use the Counter subsystem. 2058 2059 Raw counter device counts from channel Y.
