Sets the pin location of the debug pins (Serial Wire interface).

Note
Changing the pins used for debugging uncontrolled, may result in a lockout.
Parameters
[in]locationThe debug pin location to use (0-3).

__STATIC_INLINE void GPIO_DbgSWDClkEnable ( bool  enable)

Enable/disable serial wire clock pin.

Note
Disabling SWDClk will disable the debug interface, which may result in a lockout if done early in startup (before debugger is able to halt core).
Parameters
[in]enable
  • false - disable serial wire clock.
  • true - enable serial wire clock (default after reset).

__STATIC_INLINE void GPIO_DbgSWDIOEnable ( bool  enable)

void GPIO_ExtIntConfig ( GPIO_Port_TypeDef  port,
unsigned int  pin,
unsigned int  intNo,
bool  risingEdge,
bool  fallingEdge,
bool  enable 
)

Configure the GPIO external pin interrupt.

It is recommended to disable interrupts before configuring the GPIO pin interrupt. See GPIO_IntDisable() for more information.

The GPIO interrupt handler must be in place before enabling the interrupt.

Notice that any pending interrupt for the selected interrupt is cleared by this function.

Note
On series 0 devices, the pin number parameter is not used. The pin number used on these devices is hardwired to the interrupt with the same number.
On series 1 devices, the pin number can be selected freely within a group. Interrupt numbers are divided into 4 groups (intNo / 4) and valid pin number within the interrupt groups are: 0: pins 0-3 (interrupt number 0-3) 1: pins 4-7 (interrupt number 4-7) 2: pins 8-11 (interrupt number 8-11) 3: pins 12-15 (interrupt number 12-15)
Parameters
[in]portThe port to associate with the pin.
[in]pinThe pin number on the port.
[in]intNoThe interrupt number to trigger.
[in]risingEdgeSet to true if the interrupt will be enabled on the rising edge. Otherwise, false.
[in]fallingEdgeSet to true if the interrupt will be enabled on the falling edge. Otherwise, false.
[in]enableSet to true if the interrupt will be enabled after the configuration is complete. False to leave disabled. See GPIO_IntDisable() and GPIO_IntEnable().

__STATIC_INLINE void GPIO_InputSenseSet ( uint32_t  val,
uint32_t  mask 
)

Enable/disable input sensing.

Disabling input sensing if not used, can save some energy consumption.

Parameters
[in]valBitwise logic OR of one or more of:
  • GPIO_INSENSE_INT - interrupt input sensing.
  • GPIO_INSENSE_PRS - peripheral reflex system input sensing.
[in]maskMask containing bitwise logic OR of bits similar as for val used to indicate which input sense options to disable/enable.

__STATIC_INLINE void GPIO_IntClear ( uint32_t  flags)

__STATIC_INLINE void GPIO_IntConfig ( GPIO_Port_TypeDef  port,
unsigned int  pin,
bool  risingEdge,
bool  fallingEdge,
bool  enable 
)

Configure GPIO interrupt.

If reconfiguring a GPIO interrupt that is already enabled, it is generally recommended to disable it first, see GPIO_Disable().

The actual GPIO interrupt handler must be in place before enabling the interrupt.

Notice that any pending interrupt for the selected pin is cleared by this function.

Deprecated:
Deprecated function. New code should use GPIO_ExtIntConfig().
Note
A certain pin number can only be associated with one port; i.e., if GPIO interrupt 1 is assigned to port A/pin 1, then it is not possible to use pin 1 from any other ports for interrupts. Refer to the reference manual. On devices which implement GPIO_EXTIPINSEL registers a more flexible approach is possible, refer to GPIO_ExtIntConfig().
Parameters
[in]portThe port to associate with pin.
[in]pinThe pin number on the port ( == GPIO EXTI interrupt number).
[in]risingEdgeSet to true if interrupts will be enabled on rising edge, otherwise false.
[in]fallingEdgeSet to true if interrupts will be enabled on falling edge, otherwise false.
[in]enableSet to true if interrupt will be enabled after configuration completed, false to leave disabled. See GPIO_IntDisable() and GPIO_IntEnable().
