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.
