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 |
e34d2c5f JC |
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. |

610 | Note the driver will assume the last p events requested are | |
611 | to be enabled where p is however many it supports (which may | |
612 | vary depending on the exact set requested. So if you want to be | |
613 | sure you have set what you think you have, check the contents of | |
614 | these attributes after everything is configured. Drivers may | |
615 | have to buffer any parameters so that they are consistent when | |
616 | a given event type is enabled a future point (and not those for | |
617 | whatever event was previously enabled). | |

748 | For falling events the hysteresis is added to the _value attribute for | |

752 | and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event | |
753 | will get activated once in_voltage0_raw goes above 1200 and will become | |
754 | deactived again once the value falls below 1150. | |

10ba8ea9 | 1045 | Description of the scan element data storage within the buffer |
f386caa3 | 1046 | and hence the form in which it is read from user-space. |
15739cd2 JC |
1047 | Form is [be|le]:[s|u]bits/storagebits[>>shift]. |
1048 | be or le specifies big or little endian. s or u specifies if | |
f386caa3 JC |
1049 | signed (2's complement) or unsigned. bits is the number of bits |
1050 | of data and storagebits is the space (after padding) that it | |
1051 | occupies in the buffer. shift if specified, is the shift that | |
1052 | needs to be applied prior to masking out unused bits. Some | |
1053 | devices put their data in the middle of the transferred elements | |
1054 | with additional information on both sides. Note that some | |
1055 | devices will have additional information in the unused bits | |
1056 | so to get a clean value, the bits value must be used to mask | |
1057 | the buffer output value appropriately. The storagebits value | |
1058 | also specifies the data alignment. So s48/64>>2 will be a | |
1059 | signed 48 bit integer stored in a 64 bit location aligned to | |
8b417d78 | 1060 | a 64 bit boundary. To obtain the clean value, shift right 2 |
f386caa3 | 1061 | and apply a mask to zero the top 16 bits of the result. |
10ba8ea9 JC |
1062 | For other storage combinations this attribute will be extended |
1063 | appropriately. | |

1285 | KernelVersion: 4.2 | |

1287 | Description: | |
1288 | A single positive integer specifying the maximum number of scan | |
1289 | elements to wait for. | |
1290 | Poll will block until the watermark is reached. | |
1291 | Blocking read will wait until the minimum between the requested | |
1292 | read amount or the low water mark is available. | |
1293 | Non-blocking read will retrieve the available samples from the | |
1294 | buffer even if there are less samples then watermark level. This | |
1295 | allows the application to block on poll with a timeout and read | |
1296 | the available samples after the timeout expires and thus have a | |
1297 | maximum delay guarantee. | |

1300 | KernelVersion: 4.2 | |
1301 | Contact: linux-iio@vger.kernel.org | |
1302 | Description: | |
1303 | A read-only boolean value that indicates if the hardware fifo is | |
1304 | currently enabled or disabled. If the device does not have a | |
1305 | hardware fifo this entry is not present. | |
1306 | The hardware fifo is enabled when the buffer is enabled if the | |
1307 | current hardware fifo watermark level is set and other current | |
1308 | device settings allows it (e.g. if a trigger is set that samples | |
1309 | data differently that the hardware fifo does then hardware fifo | |
1310 | will not enabled). | |
1311 | If the hardware fifo is enabled and the level of the hardware | |
1312 | fifo reaches the hardware fifo watermark level the device will | |
1313 | flush its hardware fifo to the device buffer. Doing a non | |
1314 | blocking read on the device when no samples are present in the | |
1315 | device buffer will also force a flush. | |
1316 | When the hardware fifo is enabled there is no need to use a | |
1317 | trigger to use buffer mode since the watermark settings | |
1318 | guarantees that the hardware fifo is flushed to the device | |
1319 | buffer. | |

1326 | current watermark level for the hardware fifo. If the device | |
1327 | does not have a hardware fifo this entry is not present. | |
1328 | The watermark level for the hardware fifo is set by the driver | |
1329 | based on the value set by the user in buffer/watermark but | |
1330 | taking into account hardware limitations (e.g. most hardware | |
1331 | buffers are limited to 32-64 samples, some hardware buffers | |
1332 | watermarks are fixed or have minimum levels). A value of 0 | |
1333 | means that the hardware watermark is unset. | |

1340 | for the hardware fifo of this device. If the device does not | |
1341 | have a hardware fifo this entry is not present. | |
1342 | If the user sets buffer/watermark to a value less than this one, | |

1351 | have a hardware fifo this entry is not present. | |
1352 | If the user sets buffer/watermark to a value greater than this | |
1353 | one, then the hardware watermark will be capped at this value. | |

1358 | Description: | |
1359 | A list of positive integers specifying the available watermark | |
1360 | levels for the hardware fifo. This entry is optional and if it | |
1361 | is not present it means that all the values between | |
1362 | hwfifo_watermark_min and hwfifo_watermark_max are supported. | |
1363 | If the user sets buffer/watermark to a value greater than | |
1364 | hwfifo_watermak_min but not equal to any of the values in this | |
1365 | list, the driver will chose an appropriate value for the | |
