13 | An event driven driver of data capture to an in kernel buffer. | |
14 | May be provided by a device driver that also has an IIO device | |
15 | based on hardware generated events (e.g. data ready) or | |
16 | provided by a separate driver for other hardware (e.g. | |
f386caa3 | 17 | periodic timer, GPIO or high resolution timer). |
e34d2c5f JC |
18 | Contains trigger type specific elements. These do not |
19 | generalize well and hence are not documented in this file. | |
f386caa3 | 20 | X is the IIO index of the trigger. |

41 | Some devices have internal clocks. This parameter sets the | |
42 | resulting sampling frequency. In many devices this | |
8b417d78 | 43 | parameter has an effect on input filters etc. rather than |
e34d2c5f | 44 | simply controlling when the input is sampled. As this |
8b417d78 | 45 | effects data ready triggers, hardware buffers and the sysfs |

46 | direct access interfaces, it may be found in any of the |
47 | relevant directories. If it effects all of the above | |
15739cd2 | 48 | then it is to be found in the base device directory. |

659 | Description: | |
660 | Specifies the hysteresis of threshold that the device is comparing | |
661 | against for the events enabled by | |
662 | <type>Y[_name]_thresh[_(rising|falling)]_hysteresis. | |
663 | If separate attributes exist for the two directions, but | |
664 | direction is not specified for this attribute, then a single | |
665 | hysteresis value applies to both directions. | |
666 | For falling events the hysteresis is added to the _value attribute for | |
667 | this event to get the upper threshold for when the event goes back to | |
668 | normal, for rising events the hysteresis is subtracted from the _value | |
669 | attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200 | |
670 | and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event | |
671 | will get activated once in_voltage0_raw goes above 1200 and will become | |
672 | deactived again once the value falls below 1150. | |

10ba8ea9 | 934 | Description of the scan element data storage within the buffer |
f386caa3 | 935 | and hence the form in which it is read from user-space. |
15739cd2 JC |
936 | Form is [be|le]:[s|u]bits/storagebits[>>shift]. |
937 | be or le specifies big or little endian. s or u specifies if | |
f386caa3 JC |
938 | signed (2's complement) or unsigned. bits is the number of bits |
939 | of data and storagebits is the space (after padding) that it | |
940 | occupies in the buffer. shift if specified, is the shift that | |
941 | needs to be applied prior to masking out unused bits. Some | |
942 | devices put their data in the middle of the transferred elements | |
943 | with additional information on both sides. Note that some | |
944 | devices will have additional information in the unused bits | |
945 | so to get a clean value, the bits value must be used to mask | |
946 | the buffer output value appropriately. The storagebits value | |
947 | also specifies the data alignment. So s48/64>>2 will be a | |
948 | signed 48 bit integer stored in a 64 bit location aligned to | |
8b417d78 | 949 | a 64 bit boundary. To obtain the clean value, shift right 2 |
f386caa3 | 950 | and apply a mask to zero the top 16 bits of the result. |
10ba8ea9 JC |
951 | For other storage combinations this attribute will be extended |
952 | appropriately. | |
