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.

2010-11-23 08:31:16 +09:00
|
|
|
periodic timer, GPIO or high resolution timer).
|
2010-05-04 22:43:05 +09:00

Contains trigger type specific elements. These do not

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 datardy 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 as here.

(_rising|_falling) direction. If the direction is not specified,

these attributes after everything is configured. Drivers may

have to buffer any parameters so that they are consistent when

Description of the scan element data storage within the buffer
|
2010-11-23 08:31:16 +09:00
|
|
|
and hence the form in which it is read from user-space.
|
|
|
|
Form is [s|u]bits/storagebits[>>shift]. 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 a64 bit boundary. To obtain the clean value, shift right 2
|
|
|
|
and apply a mask to zero the top 16 bits of the result.

appropriately.
