Driver for tilt-switches connected via GPIOs
|
||||
============================================
|
||||
|
||||
Generic driver to read data from tilt switches connected via gpios.
|
||||
Orientation can be provided by one or more than one tilt switches,
|
||||
i.e. each tilt switch providing one axis, and the number of axes
|
||||
is also not limited.
|
||||
|
||||
|
||||
Data structures
|
||||
---------------
|
||||
|
||||
The array of struct gpio in the gpios field is used to list the gpios
|
||||
that represent the current tilt state.
|
||||
|
||||
The array of struct gpio_tilt_axis describes the axes that are reported
|
||||
to the input system. The values set therein are used for the
|
||||
input_set_abs_params calls needed to init the axes.
|
||||
|
||||
The array of struct gpio_tilt_state maps gpio states to the corresponding
|
||||
values to report. The gpio state is represented as a bitfield where the
|
||||
bit-index corresponds to the index of the gpio in the struct gpio array.
|
||||
In the same manner the values stored in the axes array correspond to
|
||||
the elements of the gpio_tilt_axis-array.
|
||||
|
||||
|
||||
