resulting sampling frequency. In many devices this

simply controlling when the input is sampled. As this

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]"

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
|
2012-06-12 21:31:27 +08:00

<type> units as specified in <type>[Y]_raw documentation.
|
2011-09-21 18:15:51 +08:00
|
|
|
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.
|
2011-09-21 18:15:51 +08:00
|
|
|
Calibbias is applied internally, offset is applied in userspace
|
|
|
|
|
to the _raw output.

iio:ad5064: Add support for ltc2617 and similar devices
The Linear Technology LTC2606, LTC2607, LTC2609, LTC2616, LTC2617,
LTC2619, LTC2626, LTC2627 and LTC2629 devices are very similar
to the AD5064 device.
This patch adds support for those devices.

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
|
2016-12-29 01:40:23 +08:00
|
|
|
deactivated again once the value falls below 1150.

Specifies the value of rate of change threshold that the

If separate attributes exist for the two directions,

but direction is not specified for this attribute,

then a single threshold value applies to both directions.

The raw or input element of the name indicates whether the

|
|
|
|
value is in raw device units or in processed units (as _raw
|
|
|
|
|
and _input do on sysfs direct channel read attributes).

Confidence value (in units as percentage) to be used
|
|
|
|

for deciding when an event should be generated. E.g for

|
|

|
running: If the confidence value reported by the sensor
|
|
|
|
|
is greater than in_activity_running_thresh_rising_value
|
|
|
|
|
then the sensor ENTERS running state. Conversely, if the

|
|
confidence value reported by the sensor is lower than
|
|
|
|
|
in_activity_running_thresh_falling_value then the sensor
|
|

Description of the scan element data storage within the buffer
|
2010-11-23 07:31:16 +08:00
|
|
|
and hence the form in which it is read from user-space.
|
2011-09-21 18:15:51 +08:00
|
|
|
Form is [be|le]:[s|u]bits/storagebits[>>shift].
|
|
|
|
|
be or le specifies big or little endian. s or u specifies if
|
2010-11-23 07:31:16 +08:00
|
|
|
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
|
2012-06-12 21:31:27 +08:00
|
|
|
a 64 bit boundary. To obtain the clean value, shift right 2
|
2010-11-23 07:31:16 +08:00
|
|
|
and apply a mask to zero the top 16 bits of the result.
|
2010-09-21 21:41:08 +08:00

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.

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.
