Function Documentation

void gpiobtn_configureButtonGpio

(

UINT16

gpioButtonConfig

)

Configure each Button GPIO This configuration is used only for enabling wakeup.

void gpiobtn_flush

(

void

)

Flush any queued button activity in FW or HW and returns the current state of the buttons.

UINT16 gpiobtn_getCurrentState

(

UINT8

port

)

Return the current button state as a bit mapped value.

0 for a button indicates that the button is not pressed, 1 indicates the button is pressed.

Parameters

port	The port ID to read.

Returns

a 16 bit map representing the current state of the buttons.

void gpiobtn_init	(	UINT16	gpioMask[],
		UINT16	gpioConfig
	)

This file defines the gpio based button interface.

Buttons are implemented as keys on this platform. The hardware reports the state of the buttons as keys. This information is translated by the button interface into a byte representing various buttons.

void gpiobtn_wakeupEnable

(

void

)

Enables wakeup from all buttons.

Also clears any pending events. Use config passed in constructor to configure GPIOs for wakeupEnable.
