Function Documentation

static void config_buttons ( int  type, int  c, uint32_t  key  )

static

Configuration function for the button sensor for all buttons.

Parameters

type	This function does nothing unless type == SENSORS_ACTIVE
c	0: disable the button, non-zero: enable
key	One of BOARD_KEY_LEFT, BOARD_KEY_RIGHT etc

Definition at line 131 of file button-sensor.c.

static int config_left ( int  type, int  value  )

static

Configuration function for the left button.

Parameters are passed onto config_buttons, which does the actual configuration Parameters are ignored. They have been included because the prototype is dictated by the core sensor API. The return value is also required by the API but otherwise ignored.

Parameters

type	passed to config_buttons as-is
value	passed to config_buttons as-is

Returns

ignored

static int config_right ( int  type, int  value  )

static

Configuration function for the right button.

Parameters are passed onto config_buttons, which does the actual configuration Parameters are ignored. They have been included because the prototype is dictated by the core sensor api. The return value is also required by the API but otherwise ignored.

Parameters

type	passed to config_buttons as-is
value	passed to config_buttons as-is

Returns

ignored

static int status ( int  type, uint32_t  key_io_id  )

static

Status function for all buttons.

Parameters

type	SENSORS_ACTIVE or SENSORS_READY
key_io_id	BOARD_IOID_KEY_LEFT, BOARD_IOID_KEY_RIGHT etc

Returns

1 if the button's port interrupt is enabled (edge detect)

This function will only be called by status_left, status_right and the called will pass the correct key_io_id

static int status_left ( int  type )

static

Status function for the left button.

Parameters

type	SENSORS_ACTIVE or SENSORS_READY

Returns

1 if the button's port interrupt is enabled (edge detect)

This function will call status. It will pass type verbatim and it will also pass the correct key_io_id

static int status_right ( int  type )

static

Status function for the right button.

Parameters

type	SENSORS_ACTIVE or SENSORS_READY

Returns

1 if the button's port interrupt is enabled (edge detect)

This function will call status. It will pass type verbatim and it will also pass the correct key_io_id
