* Button support.
|
||
|
|
*
|
||
|
|
* Description:
|
||
|
|
* up_buttoninit() must be called to initialize button resources. After
|
||
|
|
* that, up_buttons() may be called to collect the current state of all
|
||
|
|
* buttons or up_irqbutton() may be called to register button interrupt
|
||
|
|
* handlers.
|
||
|
|
*
|
||
|
|
* After up_buttoninit() has been called, up_buttons() may be called to
|
||
|
|
* collect the state of all buttons. up_buttons() returns an 8-bit bit set
|
||
|
|
* with each bit associated with a button. See the BUTTON_*_BIT and JOYSTICK_*_BIT
|
||
|
|
* definitions in board.h for the meaning of each bit.
|
||
|
|
*
|
||
|
|
* up_irqbutton() may be called to register an interrupt handler that will
|
||
|
|
* be called when a button is depressed or released. The ID value is a
|
||
|
|
* button enumeration value that uniquely identifies a button resource. See the
|
||
|
|
* BUTTON_* and JOYSTICK_* definitions in board.h for the meaning of enumeration
|
||
|
|
* value. The previous interrupt handler address is returned (so that it may
|
||
|
|
* restored, if so desired).
