|
Description: |
|
An event driven driver of data capture to an in kernel buffer. |
|
May be provided by a device driver that also has an IIO device |
|
based on hardware generated events (e.g. data ready) or |
|
provided by a separate driver for other hardware (e.g. |
|
periodic timer, GPIO or high resolution timer). |
|
|
|
Contains trigger type specific elements. These do not |
|
generalize well and hence are not documented in this file. |
|
X is the IIO index of the trigger. |

What: /sys/bus/iio/devices/iio:deviceX/label |
|
KernelVersion: 5.8 |
|
Contact: [email protected] |
|
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" |

Contact: [email protected] |
|
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. |

Description: |
|
When the internal sampling clock can only take a specific set of |
|
frequencies, we can specify the available values with: |
|
|
|
- a small discrete set of values like "0 2 4 6 8" |
|
- a range with minimum, step and maximum frequencies like |
|
"[min step max]" |

Description: |
|
Raw (unscaled no bias removal etc.) voltage measurement from |
|
channel Y. In special cases where the channel does not |
|
correspond to externally available input one of the named |
|
versions may be used. The number must always be specified and |

application of scale and offset are millivolts. |
|
|
|
Channels with 'i' and 'q' modifiers always exist in pairs and both |
|
channels refer to the same signal. The 'i' channel contains the in-phase |
|
component of the signal while the 'q' channel contains the quadrature |
|
component. |

Description: |

If known for a device, offset to be added to <type>[Y]_raw prior |

to scaling by <type>[Y]_scale in order to obtain value in the |

<type> units as specified in <type>[Y]_raw documentation. |
|
Not present if the offset is always 0 or unknown. If Y or |
|
axis <x|y|z> is not present, then the offset applies to all |
|
in channels of <type>. |
|
May be writable if a variable offset can be applied on the |
|
device. Note that this is different to calibbias which |
|
is for devices (or drivers) that apply offsets to compensate |
|
for variation between different instances of the part, typically |
|
adjusted by using some hardware supported calibration procedure. |
|
Calibbias is applied internally, offset is applied in userspace |
|
to the _raw output. |

|
|

A divide by 1, 2, 4, 8, 16, 32 or circuit generates |
|
frequencies from 62500000 Hz to 8000000000 Hz. |
|
out_altvoltage1_frequency: |
|
This channel duplicates the channel 0 frequency |
|
out_altvoltage2_frequency: |
|
A frequency doubler generates frequencies from |
|
8000000000 Hz to 16000000000 Hz. |
|
out_altvoltage3_frequency: |
|
A frequency quadrupler generates frequencies from |

|
Note: writes to one of the channels will affect the frequency of |

Event generated when channel passes a threshold in the specified |

then either the device will report an event which ever direction |

|
<type>[Y][_name]_<raw|input>_thresh_rising_value and |

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. |

|
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 |
|
against for the events enabled by |
|
<type>Y[_name]_thresh[_(rising|falling)]_hysteresis. |
|
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. |

|
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. |

The watermark level for the hardware fifo is set by the driver |
|
based on the value set by the user in buffer/watermark but |
|
taking into account hardware limitations (e.g. most hardware |
|
buffers are limited to 32-64 samples, some hardware buffers |
|
watermarks are fixed or have minimum levels). A value of 0 |
|
means that the hardware watermark is unset. |

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. |
