| Description: |
| An event driven driver of data capture to an in kernel buffer. |

| Contains trigger type specific elements. These do not |
| 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 |
| 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. |

| is for devices (or drivers) that apply offsets to compensate |
| for variation between different instances of the part, typically |

| Calibbias is applied internally, offset is applied in userspace |

| Description: |
| Event generated when channel passes a threshold in the specified |
| (_rising|_falling) direction. If the direction is not specified, |
| 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_value) or |
| <type>[Y][_name]_<raw|input>_thresh_rising_value and |
| <type>[Y][_name]_<raw|input>_thresh_falling_value may take |
| different values, but the device can only enable both thresholds |
| or neither. |
| Note the driver will assume the last p events requested are |
| to be enabled where p is how many it supports (which may vary |
| depending on the exact set requested. So if you want to be |
| sure you have set what you think you have, check the contents of |
| these attributes after everything is configured. Drivers may |
| have to buffer any parameters so that they are consistent when |
| a given event type is enabled at a future point (and not those for |

| 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. |

| Poll will block until the watermark is reached. |
| Blocking read will wait until the minimum between the requested |
| read amount or the low water mark is available. |
| Non-blocking read will retrieve the available samples from the |

| allows the application to block on poll with a timeout and read |

| What: /sys/bus/iio/devices/iio:deviceX/buffer/hwfifo_enabled |

| Contact: linux-iio@vger.kernel.org |
| 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. |

| 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 |

| 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. |
