What: /sys/bus/iio/devices/triggerX/trigger_now |

KernelVersion: 2.6.38 |

|
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. |

Contact: [email protected] |
|
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. |

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.
