Introduction

************

|
|
|
Currently, most analog and digital devices have a Infrared input for
|
|
remote controllers. Each manufacturer has their own type of control. It
|
|
is not rare for the same manufacturer to ship different types of
|
|
controls, depending on the device.
|
|
|
|
A Remote Controller interface is mapped as a normal evdev/input
|
|
interface, just like a keyboard or a mouse. So, it uses all ioctls
|
|
already defined for any other input devices.
|
|
|
|
However, remove controllers are more flexible than a normal input
|
|
device, as the IR receiver (and/or transmitter) can be used in
|
|
conjunction with a wide variety of different IR remotes.
|
|
|
|
In order to allow flexibility, the Remote Controller subsystem allows
|
|
controlling the RC-specific attributes via
|
|
:ref:`the sysfs class nodes <remote_controllers_sysfs_nodes>`.
