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 1526 of the transferred elements with additional information on both 1527 sides. Note that some devices will have additional information in 1528 the unused bits, so to get a clean value the bits value must be 1529 used to mask the buffer output value appropriately. The storagebits 1530 value also specifies the data alignment. So s48/64>>2 will be a 1531 signed 48 bit integer stored in a 64 bit location aligned to a 64 1532 bit boundary.

This is a rotation matrix which 2027 informs userspace about sensor chip's placement relative to the 2028 main hardware it is mounted on. 2029 2030 Main hardware placement is defined according to the local 2031 reference frame related to the physical quantity the sensor 2032 measures. 2033 2034 Given that the rotation matrix is defined in a board specific 2035 way (platform data and / or device-tree), the main hardware 2036 reference frame definition is left to the implementor's choice 2037 (see below for a magnetometer example). 2038 2039 Applications should apply this rotation matrix to samples so 2040 that when main hardware reference frame is aligned onto local 2041 reference frame, then sensor chip reference frame is also 2042 perfectly aligned with it. 2043 2044 Matrix is a 3x3 unitary matrix and typically looks like 2045 [0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix 2046 [1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware 2047 are perfectly aligned with each other. 2048 2049 For example, a mounting matrix for a magnetometer sensor informs 2050 userspace about sensor chip's ORIENTATION relative to the main 2051 hardware. 2052 2053 More specifically, main hardware orientation is defined with 2054 respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where : 2055 2056 * Y is in the ground plane and positive towards magnetic North ; 2057 * X is in the ground plane, perpendicular to the North axis and 2058 positive towards the East ; 2059 * Z is perpendicular to the ground plane and positive upwards. 2060 2061 An implementor might consider that for a hand-held device, a 2062 'natural' orientation would be 'front facing camera at the top'. 2063 The main hardware reference frame could then be described as : 2064 2065 * Y is in the plane of the screen and is positive towards the 2066 top of the screen ; 2067 * X is in the plane of the screen, perpendicular to Y axis, and 2068 positive towards the right hand side of the screen ; 2069 * Z is perpendicular to the screen plane and positive out of the 2070 screen. 2071 2072 Another example for a quadrotor UAV might be : 2073 2074 * Y is in the plane of the propellers and positive towards the 2075 front-view camera; 2076 * X is in the plane of the propellers, perpendicular to Y axis, 2077 and positive towards the starboard side of the UAV ; 2078 * Z is perpendicular to propellers plane and positive upwards. 2079 2080What: /sys/bus/iio/devices/iio:deviceX/in_electricalconductivity_raw 2081KernelVersion: 4.8 2082Contact: linux-iio@vger.kernel.org 2083Description: 2084 Raw (unscaled no offset etc.) electric conductivity reading. 2085 Units after application of scale and offset are siemens per 2086 meter. 2087 2088What: /sys/bus/iio/devices/iio:deviceX/in_countY_raw 2089KernelVersion: 4.10 2090Contact: linux-iio@vger.kernel.org 2091Description: 2092 This interface is deprecated; please use the Counter subsystem. 2093 2094 Raw counter device counts from channel Y.
