void LED_Display ( U32 leds )

Sets the state of all LEDs.

Parameters

leds	New state of all LEDs (1 bit per LED).

Note: The pins of all LEDs are set to GPIO output mode.

References LED_Display_Mask().

void LED_Display_Field	(	U32	field,
		U32	leds
	)

Sets as a bit-field the state of the specified LEDs.

Parameters

field	LEDs of which to set the state (1 bit per LED).
leds	New state of the specified LEDs (1 bit per LED, beginning with the first specified LED).

Note: The pins of the specified LEDs are set to GPIO output mode.

References ctz, and LED_Display_Mask().

void LED_Display_Mask	(	U32	mask,
		U32	leds
	)

Sets the state of the specified LEDs.

Parameters

mask	LEDs of which to set the state (1 bit per LED).
leds	New state of the specified LEDs (1 bit per LED).

Note: The pins of the specified LEDs are set to GPIO output mode.

U8 LED_Get_Intensity ( U32 led )

Gets the intensity of the specified LED.

Parameters

led	LED of which to get the intensity (1 bit per LED; only the least significant set bit is used).

Returns: 0, as this is not implemented.

Warning: This function is not implemented. Use the PWMA module instead.

void LED_Off ( U32 leds )

Turns off the specified LEDs.

Parameters

leds	LEDs to turn off (1 bit per LED).

Note: The pins of the specified LEDs are set to GPIO output mode.

void LED_On ( U32 leds )

Turns on the specified LEDs.

Parameters

leds	LEDs to turn on (1 bit per LED).

Note: The pins of the specified LEDs are set to GPIO output mode.

U32 LED_Read_Display ( void )

Gets the last state of all LEDs set through the LED API.

Returns: State of all LEDs (1 bit per LED).

Note: The GPIO pin configuration of all LEDs is left unchanged.

U32 LED_Read_Display_Field ( U32 field )

Gets as a bit-field the last state of the specified LEDs set through the LED API.

Parameters

field LEDs of which to get the state (1 bit per LED).

Returns: State of the specified LEDs (1 bit per LED, beginning with the first specified LED).

Note: The GPIO pin configuration of all LEDs is left unchanged.

void LED_Set_Intensity	(	U32	leds,
		U8	intensity
	)

Sets the intensity of the specified LEDs.

Parameters

leds	LEDs of which to set the intensity (1 bit per LED).
intensity	New intensity of the specified LEDs (0x00 to 0xFF).

Warning: This function is not implemented. Use the PWMA module instead.

bool LED_Test ( U32 leds )

Tests the last state of the specified LEDs set through the LED API.

Parameters

leds	LEDs of which to test the state (1 bit per LED).

Returns: true if at least one of the specified LEDs has a state on, else false.

Note: The GPIO pin configuration of all LEDs is left unchanged.
