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

provided by a separate driver for other hardware (e.g.

periodic timer, GPIO or high resolution timer).

generalize well and hence are not documented in this file.

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
|
|
effects data ready triggers, hardware buffers and the sysfs
|
|
direct access interfaces, it may be found in any of the
|
|
relevant directories. If it effects all of the above
|
|
then it is to be found in the base device directory.

Calibbias is applied internally, offset is applied in userspace

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

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

<type>Y[_name]_thresh[_rising|falling]_en.

If separate attributes exist for the two directions, but

The raw or input element of the name indicates whether the

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.

Non-blocking read will retrieve the available samples from the

the available samples after the timeout expires and thus have a

Description:
|
|
A read-only value indicating the bytes of data available in the
|
|
buffer. In the case of an output buffer, this indicates the
|
|
amount of empty space available to write data to. In the case of
|
|
an input buffer, this indicates the amount of data available for
|
|
reading.

|
|
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:
|
|
A read/write property to provide capability to delay reporting of
|
|
samples till a timeout is reached. This allows host processors to
|
|
sleep, while the sensor is storing samples in its internal fifo.
|
|
The maximum timeout in seconds can be specified by setting
|
|
hwfifo_timeout.The current delay can be read by reading
|
|
hwfifo_timeout. A value of 0 means that there is no timeout.

Description:
|
|
Read-only entry that contains a single integer specifying the
|
|
current watermark level for the hardware fifo. If the device
|
|
does not have a hardware fifo this entry is not present.
|
|
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.

If the user sets buffer/watermark to a value less than this one,

|
|
If the user sets buffer/watermark to a value greater than this

If the user sets buffer/watermark to a value greater than

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.
