As this 106 affects data ready triggers, hardware buffers and the sysfs 107 direct access interfaces, it may be found in any of the 108 relevant directories. If it affects all of the above 109 then it is to be found in the base device directory. 110 111 The stm32-timer-trigger has the additional characteristic that 112 a sampling_frequency of 0 is defined to stop sampling. 113 114What: /sys/bus/iio/devices/iio:deviceX/sampling_frequency_available 115What: /sys/bus/iio/devices/iio:deviceX/in_intensity_sampling_frequency_available 116What: /sys/bus/iio/devices/iio:deviceX/in_proximity_sampling_frequency_available 117What: /sys/.../iio:deviceX/buffer/sampling_frequency_available 118What: /sys/bus/iio/devices/triggerX/sampling_frequency_available 119KernelVersion: 2.6.35 120Contact: linux-iio@vger.kernel.org 121Description: 122 When the internal sampling clock can only take a specific set of 123 frequencies, we can specify the available values with: 124 125 - a small discrete set of values like "0 2 4 6 8" 126 - a range with minimum, step and maximum frequencies like 127 "[min step max]" 128 129What: /sys/bus/iio/devices/iio:deviceX/oversampling_ratio 130KernelVersion: 2.6.38 131Contact: linux-iio@vger.kernel.org 132Description: 133 Hardware dependent ADC oversampling.

As the reading is of the difference 203 between the two inputs, this should not be applied to the _raw 204 reading by userspace (unlike _offset) and unlike calibbias 205 it does not affect the differential value measured because 206 the effect of _zeropoint cancels out across the two inputs 207 that make up the differential pair. It's purpose is to bring 208 the individual signals, before the differential is measured, 209 within the measurement range of the device. The naming is 210 chosen because if the separate inputs that make the 211 differential pair are drawn on a graph in their 212 _raw units, this is the value that the zero point on the 213 measurement axis represents. It is expressed with the 214 same scaling as _raw. 215 216What: /sys/bus/iio/devices/iio:deviceX/in_temp_raw 217What: /sys/bus/iio/devices/iio:deviceX/in_tempY_raw 218What: /sys/bus/iio/devices/iio:deviceX/in_temp_x_raw 219What: /sys/bus/iio/devices/iio:deviceX/in_temp_y_raw 220What: /sys/bus/iio/devices/iio:deviceX/in_temp_ambient_raw 221What: /sys/bus/iio/devices/iio:deviceX/in_temp_object_raw 222KernelVersion: 2.6.35 223Contact: linux-iio@vger.kernel.org 224Description: 225 Raw (unscaled no bias removal etc.) temperature measurement. 226 If an axis is specified it generally means that the temperature 227 sensor is associated with one part of a compound device (e.g. 228 a gyroscope axis).

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.
