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. |

48 | Some devices have internal clocks. This parameter sets the | |

10ba8ea9 | 1119 | Description of the scan element data storage within the buffer |
f386caa3 | 1120 | and hence the form in which it is read from user-space. |
15739cd2 JC |
1121 | Form is [be|le]:[s|u]bits/storagebits[>>shift]. |
1122 | be or le specifies big or little endian. s or u specifies if | |
f386caa3 JC |
1123 | signed (2's complement) or unsigned. bits is the number of bits |
1124 | of data and storagebits is the space (after padding) that it | |
1125 | occupies in the buffer. shift if specified, is the shift that | |
1126 | needs to be applied prior to masking out unused bits. Some | |
1127 | devices put their data in the middle of the transferred elements | |
1128 | with additional information on both sides. Note that some | |
1129 | devices will have additional information in the unused bits | |
1130 | so to get a clean value, the bits value must be used to mask | |
1131 | the buffer output value appropriately. The storagebits value | |
1132 | also specifies the data alignment. So s48/64>>2 will be a | |
1133 | signed 48 bit integer stored in a 64 bit location aligned to | |
8b417d78 | 1134 | a 64 bit boundary. To obtain the clean value, shift right 2 |
f386caa3 | 1135 | and apply a mask to zero the top 16 bits of the result. |
10ba8ea9 JC |
1136 | For other storage combinations this attribute will be extended |
1137 | appropriately. | |

1396 | Description: | |
1397 | A read-only boolean value that indicates if the hardware fifo is | |
1398 | currently enabled or disabled. If the device does not have a | |
1399 | hardware fifo this entry is not present. | |
1400 | The hardware fifo is enabled when the buffer is enabled if the | |
1401 | current hardware fifo watermark level is set and other current | |
1402 | device settings allows it (e.g. if a trigger is set that samples | |
1403 | data differently that the hardware fifo does then hardware fifo | |
1404 | will not enabled). | |
1405 | If the hardware fifo is enabled and the level of the hardware | |
1406 | fifo reaches the hardware fifo watermark level the device will | |
1407 | flush its hardware fifo to the device buffer. Doing a non | |
1408 | blocking read on the device when no samples are present in the | |
1409 | device buffer will also force a flush. | |
1410 | When the hardware fifo is enabled there is no need to use a | |
1411 | trigger to use buffer mode since the watermark settings | |
1412 | guarantees that the hardware fifo is flushed to the device | |
1413 | buffer. | |

1533 | main hardware it is mounted on. | |
1534 | Main hardware placement is defined according to the local | |
1535 | reference frame related to the physical quantity the sensor | |
1536 | measures. | |
1537 | Given that the rotation matrix is defined in a board specific | |
1538 | way (platform data and / or device-tree), the main hardware | |
1539 | reference frame definition is left to the implementor's choice | |
1540 | (see below for a magnetometer example). | |
1541 | Applications should apply this rotation matrix to samples so | |
1542 | that when main hardware reference frame is aligned onto local | |
1543 | reference frame, then sensor chip reference frame is also | |
1544 | perfectly aligned with it. | |
1545 | Matrix is a 3x3 unitary matrix and typically looks like | |
1546 | [0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix | |
1547 | [1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware | |
1548 | are perfectly aligned with each other. | |
1549 | ||
1550 | For example, a mounting matrix for a magnetometer sensor informs | |
1551 | userspace about sensor chip's ORIENTATION relative to the main | |
1552 | hardware. | |
1553 | More specifically, main hardware orientation is defined with | |
1554 | respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where : | |
1555 | * Y is in the ground plane and positive towards magnetic North ; | |
1556 | * X is in the ground plane, perpendicular to the North axis and | |
1557 | positive towards the East ; | |
1558 | * Z is perpendicular to the ground plane and positive upwards. | |
1559 | ||
1560 | An implementor might consider that for a hand-held device, a | |
1561 | 'natural' orientation would be 'front facing camera at the top'. | |
1562 | The main hardware reference frame could then be described as : | |
1563 | * Y is in the plane of the screen and is positive towards the | |
1564 | top of the screen ; | |
1565 | * X is in the plane of the screen, perpendicular to Y axis, and | |
1566 | positive towards the right hand side of the screen ; | |
1567 | * Z is perpendicular to the screen plane and positive out of the | |
1568 | screen. | |
1569 | Another example for a quadrotor UAV might be : | |
1570 | * Y is in the plane of the propellers and positive towards the | |
1571 | front-view camera; | |
1572 | * X is in the plane of the propellers, perpendicular to Y axis, | |
1573 | and positive towards the starboard side of the UAV ; | |
1574 | * Z is perpendicular to propellers plane and positive upwards. | |
