| KernelVersion: 5.8 |
| Contact: linux-iio@vger.kernel.org |
| Description: |
| Optional symbolic label for a device. |
| This is useful for userspace to be able to better identify an |
| individual device. |
| |
| The contents of the label are free-form, but there are some |
| standardized uses: |
| |
| For proximity sensors which give the proximity (of a person) to |
| a certain wlan or wwan antenna the following standardized labels |
| are used: |
| |
| * "proximity-wifi" |
| * "proximity-lte" |
| * "proximity-wifi-lte" |
| * "proximity-wifi-left" |
| * "proximity-wifi-right" |
| |
| These are used to indicate to userspace that these proximity |
| sensors may be used to tune transmit power to ensure that |
| Specific Absorption Rate (SAR) limits are honored. |
| The "-left" and "-right" labels are for devices with multiple |
| antennas. |
| |
| In some laptops/tablets the standardized proximity sensor labels |
| instead indicate proximity to a specific part of the device: |
| |
| * "proximity-palmrest" indicates proximity to the keyboard's palmrest |
| * "proximity-palmrest-left" indicates proximity to the left part of the palmrest |
| * "proximity-palmrest-right" indicates proximity to the right part of the palmrest |
| * "proximity-lap" indicates the device is being used on someone's lap |
| |
| Note "proximity-lap" is special in that its value may be |
| calculated by firmware from other sensor readings, rather then |
| being a raw sensor reading. |
| |
| For accelerometers used in 2-in-1s with 360° (yoga-style) hinges, |
| which have an accelerometer in both their base and their display, |
| the following standardized labels are used: |
| |
| * "accel-base" |
| * "accel-display" |
| |
| For devices where an accelerometer is housed in the swivel camera subassembly |
| (for AR application), the following standardized label is used: |
| |
| * "accel-camera" |

| Description: |
| Some devices have internal clocks. This parameter sets the |
| resulting sampling frequency. In many devices this |
| parameter has an effect on input filters etc. rather than |
| simply controlling when the input is sampled. As this |
| affects data ready triggers, hardware buffers and the sysfs |
| direct access interfaces, it may be found in any of the |
| relevant directories. If it affects all of the above |
| then it is to be found in the base device directory. |
| |
| The stm32-timer-trigger has the additional characteristic that |
| a sampling_frequency of 0 is defined to stop sampling. |

| What: /sys/.../iio:deviceX/in_capacitanceY-capacitanceZ_zeropoint |
| KernelVersion: 6.1 |
| Contact: linux-iio@vger.kernel.org |
| Description: |
| For differential channels, this an offset that is applied |
| equally to both inputs. As the reading is of the difference |
| between the two inputs, this should not be applied to the _raw |
| reading by userspace (unlike _offset) and unlike calibbias |
| it does not affect the differential value measured because |
| the effect of _zeropoint cancels out across the two inputs |
| that make up the differential pair. It's purpose is to bring |
| the individual signals, before the differential is measured, |
| within the measurement range of the device. The naming is |
| chosen because if the separate inputs that make the |
| differential pair are drawn on a graph in their |
| _raw units, this is the value that the zero point on the |
| measurement axis represents. It is expressed with the |
| same scaling as _raw. |

| Description: |
| Event generated when channel passes a threshold in the specified |

| a single threshold value is passed in (e.g. |

| <type>[Y][_name]_<raw|input>_thresh_rising_value and |
| <type>[Y][_name]_<raw|input>_thresh_falling_value may take |
| different values, but the device can only enable both thresholds |
| or neither. |
| |
| Note the driver will assume the last p events requested are |
| to be enabled where p is how many it supports (which may vary |
| depending on the exact set requested. So if you want to be |
| sure you have set what you think you have, check the contents of |
| these attributes after everything is configured. Drivers may |
| have to buffer any parameters so that they are consistent when |
| a given event type is enabled at a future point (and not those for |
| whatever event was previously enabled). |

| Description: |
| Event generated when channel passes a threshold on the rate of |
| change (1st differential) in the specified (_rising|_falling) |
| direction. If the direction is not specified, then either the |
| device will report an event which ever direction a single |
| threshold value is passed in (e.g. |
| <type>[Y][_name]_<raw|input>_roc_value) or |
| <type>[Y][_name]_<raw|input>_roc_rising_value and |
| <type>[Y][_name]_<raw|input>_roc_falling_value may take |
| different values, but the device can only enable both rate of |
| change thresholds or neither. |
| |
| Note the driver will assume the last p events requested are |
| to be enabled where p is however many it supports (which may |
| vary depending on the exact set requested. So if you want to be |
| sure you have set what you think you have, check the contents of |
| these attributes after everything is configured. Drivers may |
| have to buffer any parameters so that they are consistent when |
| a given event type is enabled a future point (and not those for |
| whatever event was previously enabled). |

| Description: |
| Adaptive thresholds are similar to normal fixed thresholds |
| but the value is expressed as an offset from a value which |
| provides a low frequency approximation of the channel itself. |
| Thus these detect if a rapid change occurs in the specified |
| direction which crosses tracking value + offset. |
| Tracking value calculation is devices specific. |

| Contact: linux-iio@vger.kernel.org |
| Description: |
| When adaptive thresholds are used, the tracking signal |
| may adjust too slowly to step changes in the raw signal. |
| Thus these specify the time in seconds for which the |
| difference between the slow tracking signal and the raw |
| signal is allowed to remain out-of-range before a reset |
| event occurs in which the tracking signal is made equal |
| to the raw signal, allowing slow tracking to resume and the |
| adaptive threshold event detection to function as expected. |

| Description: |
| Specifies the hysteresis of threshold that the device is comparing |

| If separate attributes exist for the two directions, but |
| direction is not specified for this attribute, then a single |
| hysteresis value applies to both directions. |
| |
| For falling events the hysteresis is added to the _value attribute for |
| this event to get the upper threshold for when the event goes back to |
| normal, for rising events the hysteresis is subtracted from the _value |
| attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200 |
| and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event |
| will get activated once in_voltage0_raw goes above 1200 and will become |
| deactivated again once the value falls below 1150. |

| Description: |
| Description of the scan element data storage within the buffer |
| and hence the form in which it is read from user-space. |
| Form is [be|le]:[s|u]bits/storagebits[>>shift]. |
| be or le specifies big or little endian. s or u specifies if |
| signed (2's complement) or unsigned. bits is the number of bits |
| of data and storagebits is the space (after padding) that it |
| occupies in the buffer. shift if specified, is the shift that |
| needs to be applied prior to masking out unused bits. Some |
| devices put their data in the middle of the transferred elements |
| with additional information on both sides. Note that some |
| devices will have additional information in the unused bits |
| so to get a clean value, the bits value must be used to mask |
| the buffer output value appropriately. The storagebits value |
| also specifies the data alignment. So s48/64>>2 will be a |
| signed 48 bit integer stored in a 64 bit location aligned to |
| a 64 bit boundary. To obtain the clean value, shift right 2 |
| and apply a mask to zero the top 16 bits of the result. |
| For other storage combinations this attribute will be extended |
| appropriately. |

| What: /sys/bus/iio/devices/iio:deviceX/buffer/hwfifo_enabled |
| KernelVersion: 4.2 |
| Contact: linux-iio@vger.kernel.org |
| Description: |
| A read-only boolean value that indicates if the hardware fifo is |
| currently enabled or disabled. If the device does not have a |
| hardware fifo this entry is not present. |
| The hardware fifo is enabled when the buffer is enabled if the |
| current hardware fifo watermark level is set and other current |
| device settings allows it (e.g. if a trigger is set that samples |
| data differently that the hardware fifo does then hardware fifo |
| will not enabled). |
| |
| If the hardware fifo is enabled and the level of the hardware |
| fifo reaches the hardware fifo watermark level the device will |
| flush its hardware fifo to the device buffer. Doing a non |
| blocking read on the device when no samples are present in the |
| device buffer will also force a flush. |
| |
| When the hardware fifo is enabled there is no need to use a |
| trigger to use buffer mode since the watermark settings |
| guarantees that the hardware fifo is flushed to the device |
| buffer. |

| Description: |
| Mounting matrix for IIO sensors. This is a rotation matrix which |
| informs userspace about sensor chip's placement relative to the |
| main hardware it is mounted on. |
| |
| Main hardware placement is defined according to the local |
| reference frame related to the physical quantity the sensor |
| measures. |
| |
| Given that the rotation matrix is defined in a board specific |
| way (platform data and / or device-tree), the main hardware |
| reference frame definition is left to the implementor's choice |
| (see below for a magnetometer example). |
| |
| Applications should apply this rotation matrix to samples so |
| that when main hardware reference frame is aligned onto local |
| reference frame, then sensor chip reference frame is also |
| perfectly aligned with it. |
| |
| Matrix is a 3x3 unitary matrix and typically looks like |
| [0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix |
| [1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware |
| are perfectly aligned with each other. |
| |
| For example, a mounting matrix for a magnetometer sensor informs |
| userspace about sensor chip's ORIENTATION relative to the main |
| hardware. |
| |
| More specifically, main hardware orientation is defined with |
| respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where : |
| |
| * Y is in the ground plane and positive towards magnetic North ; |
| * X is in the ground plane, perpendicular to the North axis and |
| positive towards the East ; |
| * Z is perpendicular to the ground plane and positive upwards. |
| |
| An implementor might consider that for a hand-held device, a |
| 'natural' orientation would be 'front facing camera at the top'. |
| The main hardware reference frame could then be described as : |
| |
| * Y is in the plane of the screen and is positive towards the |
| top of the screen ; |
| * X is in the plane of the screen, perpendicular to Y axis, and |
| positive towards the right hand side of the screen ; |
| * Z is perpendicular to the screen plane and positive out of the |
| screen. |
| |
| Another example for a quadrotor UAV might be : |
| |
| * Y is in the plane of the propellers and positive towards the |
| front-view camera; |
| * X is in the plane of the propellers, perpendicular to Y axis, |
| and positive towards the starboard side of the UAV ; |
| * Z is perpendicular to propellers plane and positive upwards. |
