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.

2010-11-22 23:31:16 +00:00
|
|
|
periodic timer, GPIO or high resolution timer).
|
2010-05-04 14:43:05 +01:00
|
|
|
Contains trigger type specific elements. These do not

generalize well and hence are not documented in this file.
|
2010-11-22 23:31:16 +00:00

resulting sampling frequency. In many devices this

simply controlling when the input is sampled. As this

effects data ready triggers, hardware buffers and the sysfs

relevant directories. If it effects all of the above

2011-09-21 11:15:51 +01:00

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 15:31:27 +02:00
|
|
|
<type> units as specified in <type>[Y]_raw documentation.
|
2011-09-21 11:15:51 +01:00
|
|
|
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>.
|
2010-11-22 23:31:16 +00:00
|
|
|
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 11:15:51 +01:00
|
|
|
Calibbias is applied internally, offset is applied in userspace
|
|
|
|
|
to the _raw output.

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>_thresh_rising_value and

sure you have set what you think you have, check the contents of

have to buffer any parameters so that they are consistent when

Description of the scan element data storage within the buffer

2010-11-22 23:31:16 +00:00
|
|
|
and hence the form in which it is read from user-space.
|
2011-09-21 11:15:51 +01:00
|
|
|
Form is [be|le]:[s|u]bits/storagebits[>>shift].
|
|
|
|
|
be or le specifies big or little endian. s or u specifies if
|
2010-11-22 23:31:16 +00:00
|
|
|
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 15:31:27 +02:00
|
|
|
a 64 bit boundary. To obtain the clean value, shift right 2
|
2010-11-22 23:31:16 +00:00
|
|
|
and apply a mask to zero the top 16 bits of the result.
|
2010-09-21 14:41:08 +01:00
|
|
|
For other storage combinations this attribute will be extended
|
|
|
|
|
appropriately.
