What: /sys/bus/iio/devices/triggerX/trigger_now
KernelVersion: 2.6.38
Contact: [email protected]
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.
What: /sys/bus/iio/devices/iio_sysfs_trigger/add_trigger
KernelVersion: 2.6.39
Contact: [email protected]
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.
What: /sys/bus/iio/devices/iio_sysfs_trigger/remove_trigger
KernelVersion: 2.6.39
Contact: [email protected]
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.
