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.
