What: /sys/bus/iio/devices/triggerX/trigger_now KernelVersion: 2.6.38 Contact: linux-iio@vger.kernel.org Description: 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.
