|
|
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.

|
|
Description:
|
|
The name attribute holds a description string for the current
|
|
trigger. In order to associate the trigger with an IIO device
|
|
one should write this name string to
|
|
/sys/bus/iio/devices/iio:deviceY/trigger/current_trigger.

|
|
Description:
|
|
This attribute is provided by the iio-trig-sysfs stand-alone
|
|
driver and it is used to activate the creation of a new trigger.
|
|
In order to achieve this, one should write a positive integer
|
|
into the associated file, which will serve as the id of the
|
|
trigger. If the trigger with the specified id is already present
|
|
in the system, an invalid argument message will be returned.

|
|
Description:
|
|
This attribute is used to unregister and delete a previously
|
|
created trigger from the list of available triggers. In order to
|
|
achieve this, one should write a positive integer into the
|
|
associated file, representing the id of the trigger that needs
|
|
to be removed. If the trigger can't be found, an invalid
|
|
argument message will be returned to the user.
