void GPIO_EventOutputConfig	(	uint8_t	GPIO_PortSource,
		uint8_t	GPIO_PinSource
	)

Selects the GPIO pin used as Event output.

Parameters:

GPIO_PortSource,:	selects the GPIO port to be used as source for Event output. This parameter can be GPIO_PortSourceGPIOx where x can be (A..E).
GPIO_PinSource,:	specifies the pin for the Event output. This parameter can be GPIO_PinSourcex where x can be (0..15).

Return values:

None

void GPIO_EventOutputCmd

(

FunctionalState

NewState

)

Enables or disables the Event Output.

Parameters:

NewState,:

new state of the Event output. This parameter can be: ENABLE or DISABLE.

Return values:

None

void GPIO_PinRemapConfig	(	uint32_t	GPIO_Remap,
		FunctionalState	NewState
	)

Changes the mapping of the specified pin.

Parameters:

GPIO_Remap,:

selects the pin to remap. This parameter can be one of the following values: GPIO_Remap_SPI1 GPIO_Remap_I2C1 GPIO_Remap_USART1 GPIO_Remap_USART2 GPIO_PartialRemap_USART3 GPIO_FullRemap_USART3 GPIO_PartialRemap_TIM1 GPIO_FullRemap_TIM1 GPIO_PartialRemap1_TIM2 GPIO_PartialRemap2_TIM2 GPIO_FullRemap_TIM2 GPIO_PartialRemap_TIM3 GPIO_FullRemap_TIM3 GPIO_Remap_TIM4 GPIO_Remap1_CAN1 GPIO_Remap2_CAN1 GPIO_Remap_PD01 GPIO_Remap_TIM5CH4_LSI GPIO_Remap_ADC1_ETRGINJ GPIO_Remap_ADC1_ETRGREG GPIO_Remap_ADC2_ETRGINJ GPIO_Remap_ADC2_ETRGREG GPIO_Remap_ETH GPIO_Remap_CAN2 GPIO_Remap_SWJ_NoJTRST GPIO_Remap_SWJ_JTAGDisable GPIO_Remap_SWJ_Disable GPIO_Remap_SPI3 GPIO_Remap_TIM2ITR1_PTP_SOF GPIO_Remap_PTP_PPS GPIO_Remap_TIM15 GPIO_Remap_TIM16 GPIO_Remap_TIM17 GPIO_Remap_CEC GPIO_Remap_TIM1_DMA GPIO_Remap_TIM9 GPIO_Remap_TIM10 GPIO_Remap_TIM11 GPIO_Remap_TIM13 GPIO_Remap_TIM14 GPIO_Remap_FSMC_NADV

Note:

If the GPIO_Remap_TIM2ITR1_PTP_SOF is enabled the TIM2 ITR1 is connected to Ethernet PTP output. When Reset TIM2 ITR1 is connected to USB OTG SOF output.

Parameters:
