| 4 | Description: |
| 5 | This file is provided by the iio-trig-sysfs stand-alone trigger |
| 6 | driver. Writing this file with any value triggers an event |
| 7 | driven driver, associated with this trigger, to capture data |
| 8 | into an in kernel buffer. This approach can be valuable during |
| 9 | automated testing or in situations, where other trigger methods |
| 10 | are not applicable. For example no RTC or spare GPIOs. |
| 11 | X is the IIO index of the trigger. |
