What: /sys/bus/iio/devices/triggerX/trigger_now
KernelVersion: 2.6.38
This file is provided by the iio-trig-sysfs stand-alone trigger
driver. Writing this file with any value triggers an event
driven driver, associated with this trigger, to capture data
into an in kernel buffer. This approach can be valuable during
automated testing or in situations, where other trigger methods
are not applicable. For example no RTC or spare GPIOs.
X is the IIO index of the trigger.
