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.
