STATIC INLINE void Chip_GPIO_SetPortToggle ( LPC_GPIO_T *  pGPIO,
uint8_t  port,
uint32_t  pins 
)

Toggle selected GPIO output pins to the opposite state.

Parameters:
pGPIO: The base of GPIO peripheral on the chip
port: Port number
pins: pins (0..n) to toggle
Returns:
None
Note:
Any bit set as a '0' will not have it's state changed. This only applies to ports configured as an output.

STATIC INLINE void Chip_GPIO_SetPortValue ( LPC_GPIO_T *  pGPIO,
uint8_t  port,
uint32_t  value 
)

Set all GPIO raw pin states (regardless of masking)

Parameters:
pGPIO: The base of GPIO peripheral on the chip
port: Port number
value: Value to set all GPIO pin states (0..n) to
Returns:
Nothing

void Chip_GPIO_SetupPinInt ( LPC_GPIO_T *  pGPIO,
uint8_t  port,
uint8_t  pin,
GPIO_INT_MODE_T  mode 
)

Composite function for setting up a full interrupt configuration for a single pin.

Parameters:
pGPIO: The base of GPIO peripheral on the chip
port: Port number
pin: Pin number (0..11)
modeFlags: GPIO interrupt mode selection
Returns:
Nothing
STATIC INLINE void Chip_GPIO_SetValue ( LPC_GPIO_T *  pGPIO,
uint8_t  port,
uint32_t  bit 
)

Set a GPIO port/bit to the high state.

Parameters:
pGPIO: The base of GPIO peripheral on the chip
port: Port number
bit: Bit(s) in the port to set high
Returns:
None
Note:
Any bit set as a '0' will not have it's state changed. This only applies to ports configured as an output. It is recommended to use the Chip_GPIO_SetPortOutHigh() function instead.

void Chip_GPIO_WriteDirBit ( LPC_GPIO_T *  pGPIO,
uint32_t  port,
uint8_t  bit,
bool  setting 
)

Seta GPIO direction.

Parameters:
pGPIO: The base of GPIO peripheral on the chip
port: GPIO port to set
bit: GPIO bit to set
setting: true for output, false for input
Returns:
Nothing
Note:
It is recommended to use the Chip_GPIO_SetPinDIROutput(), Chip_GPIO_SetPinDIRInput() or Chip_GPIO_SetPinDIR() functions instead of this function.
STATIC INLINE void Chip_GPIO_WritePortBit ( LPC_GPIO_T *  pGPIO,
uint32_t  port,
uint8_t  bit,
bool  setting 
)

Set a GPIO port/bit state.

Parameters:
pGPIO: The base of GPIO peripheral on the chip
port: GPIO port to set
bit: GPIO bit to set
setting: true for high, false for low
Returns:
Nothing
