static uint32_t GPIODirModeGet ( uint32_t ui32Pin )

inlinestatic

Gets the direction of a pin.

This function gets the direction and control mode for a specified pin on the selected GPIO port. The pin can be configured as either an input or output under software control.

Parameters

ui32Pin

is the pin number.

Returns

Returns one of the enumerated data types:

GPIO_DIR_MODE_IN : Software controlled input.
GPIO_DIR_MODE_OUT : Software controlled output.

Definition at line 196 of file gpio.h.

static void GPIODirModeSet	(	uint32_t	ui32Pins,
		uint32_t	ui32Dir
	)

inlinestatic

Sets the direction of the specified pin(s).

This function will set the specified pin(s) on the GPIO port as either an input or output under software control.

Parameters

ui32Pins	is the bit-packed representation of the pin(s) The parameter must be a bitwise OR'ed combination of the following: GPIO_PIN_0 ... GPIO_PIN_31
ui32Dir	is the direction of the pin(s): GPIO_DIR_MODE_IN : Software controlled input. GPIO_DIR_MODE_OUT : Software controlled output.

Returns: None

static void GPIOEventClear ( uint32_t ui32Pins )

inlinestatic

Clear an IO event on a pin.

Parameters

ui32Pins

specifies the pins to clear the events on. The parameter must be a bitwise OR'ed combination of the following:

Returns: None

static uint32_t GPIOEventGet ( uint32_t ui32Pin )

inlinestatic

Get the event status of a specific pin.

Parameters

ui32Pin

is the pins to toggle. The parameter must be one of:

Returns: Returns the current event status on a specific GPIO

Definition at line 353 of file gpio.h.

Referenced by IOCIntStatus().

static void GPIOPinClear ( uint32_t ui32Pins )

inlinestatic

Clear specific pin(s).

Parameters

ui32Pins

are the pins to clear The parameter must be a bitwise OR'ed combination of the following:

Returns: None

Definition at line 299 of file gpio.h.

static uint32_t GPIOPinRead ( uint32_t ui32Pins )

inlinestatic

Read the value of specific pin(s).

Note: The value of the GPIO can always be read even if GPIO is configured as output. However, input enable must be set in the IOC module.

Parameters

ui32Pins

is the bit-packed representation of the pin(s) to read. The parameter must be a bitwise OR'ed combination of the following:

Returns: Returns the value of the specified pin(s).

Definition at line 272 of file gpio.h.

static void GPIOPinToggle ( uint32_t ui32Pins )

inlinestatic

Toggle specific pin(s).

Parameters

ui32Pins

is the pins to toggle. The parameter must be a bitwise OR'ed combination of the following:

Returns: None

Definition at line 326 of file gpio.h.

static void GPIOPinWrite	(	uint32_t	ui32Pins,
		uint32_t	ui32Val
	)

inlinestatic

Write to pin(s).

All the specified pins will be set to the same value, either '0' or '1'.

Parameters

ui32Pins	is the bit-packed representation of the GPIO(s) to set. The parameter must be a bitwise OR'ed combination of the following: GPIO_PIN_0 ... GPIO_PIN_31
ui32Val	is the value to write on the specified GPIO(s): 0 : Set the GPIO(s) to 0 (low). 1 : Set the GPIO(s) to 1 (high).

Returns: None
