* 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). |
