As the reading is of the difference 222 between the two inputs, this should not be applied to the _raw 223 reading by userspace (unlike _offset) and unlike calibbias 224 it does not affect the differential value measured because 225 the effect of _zeropoint cancels out across the two inputs 226 that make up the differential pair. It's purpose is to bring 227 the individual signals, before the differential is measured, 228 within the measurement range of the device. The naming is 229 chosen because if the separate inputs that make the 230 differential pair are drawn on a graph in their 231 _raw units, this is the value that the zero point on the 232 measurement axis represents.

Some devices put their data in the middle 1528 of the transferred elements with additional information on both 1529 sides. Note that some devices will have additional information in 1530 the unused bits, so to get a clean value the bits value must be 1531 used to mask the buffer output value appropriately. The storagebits 1532 value also specifies the data alignment. So s48/64>>2 will be a 1533 signed 48-bit integer stored in a 64-bit location aligned to a 1534 64-bit boundary.

This is a rotation matrix which 2029 informs userspace about sensor chip's placement relative to the 2030 main hardware it is mounted on. 2031 2032 Main hardware placement is defined according to the local 2033 reference frame related to the physical quantity the sensor 2034 measures. 2035 2036 Given that the rotation matrix is defined in a board specific 2037 way (platform data and / or device-tree), the main hardware 2038 reference frame definition is left to the implementor's choice 2039 (see below for a magnetometer example). 2040 2041 Applications should apply this rotation matrix to samples so 2042 that when main hardware reference frame is aligned onto local 2043 reference frame, then sensor chip reference frame is also 2044 perfectly aligned with it. 2045 2046 Matrix is a 3x3 unitary matrix and typically looks like 2047 [0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix 2048 [1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware 2049 are perfectly aligned with each other. 2050 2051 For example, a mounting matrix for a magnetometer sensor informs 2052 userspace about sensor chip's ORIENTATION relative to the main 2053 hardware. 2054 2055 More specifically, main hardware orientation is defined with 2056 respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where : 2057 2058 * Y is in the ground plane and positive towards magnetic North ; 2059 * X is in the ground plane, perpendicular to the North axis and 2060 positive towards the East ; 2061 * Z is perpendicular to the ground plane and positive upwards. 2062 2063 An implementor might consider that for a hand-held device, a 2064 'natural' orientation would be 'front facing camera at the top'. 2065 The main hardware reference frame could then be described as : 2066 2067 * Y is in the plane of the screen and is positive towards the 2068 top of the screen ; 2069 * X is in the plane of the screen, perpendicular to Y axis, and 2070 positive towards the right hand side of the screen ; 2071 * Z is perpendicular to the screen plane and positive out of the 2072 screen. 2073 2074 Another example for a quadrotor UAV might be : 2075 2076 * Y is in the plane of the propellers and positive towards the 2077 front-view camera; 2078 * X is in the plane of the propellers, perpendicular to Y axis, 2079 and positive towards the starboard side of the UAV ; 2080 * Z is perpendicular to propellers plane and positive upwards. 2081 2082What: /sys/bus/iio/devices/iio:deviceX/in_electricalconductivity_raw 2083KernelVersion: 4.8 2084Contact: linux-iio@vger.kernel.org 2085Description: 2086 Raw (unscaled no offset etc.) electric conductivity reading. 2087 Units after application of scale and offset are siemens per 2088 meter. 2089 2090What: /sys/bus/iio/devices/iio:deviceX/in_countY_raw 2091KernelVersion: 4.10 2092Contact: linux-iio@vger.kernel.org 2093Description: 2094 This interface is deprecated; please use the Counter subsystem. 2095 2096 Raw counter device counts from channel Y.
