Function Documentation

◆ GPIO_SetPinAltFun()

void GPIO_SetPinAltFun	(	GPIO_TypeDef *	GPIOx,
		uint32_t	Pin,
		uint32_t	AltFun
	)

Set the alternate function of the pin. There are 2 registers to be addressed. It depends on the pin location and it is valid for each GPIO port.

Pins 00-07 are in ARFL
Pins 08-16 are in ARFH
Parameters

[in] GPIOx GPIO Handler

[in] Pin [e.g. pin 8 is 0b 0000 0000 0000 0000 0000 0001 0000 0000]

[in] AltFun [e.g. Alternate Function 9 is 0b 0000 0000 0000 0000 0000 0010 0000 0000]

Here is the caller graph for this function:

◆ GPIO_SetPinMode()

void GPIO_SetPinMode	(	GPIO_TypeDef *	GPIOx,
		uint32_t	Pin,
		uint32_t	Mode
	)

Set the mode of the pin. See GPIOx_MODER.

Parameters

[in]	GPIOx	GPIO Handler
[in]	Pin	[e.g. pin 8 is 0b 0000 0000 0000 0000 0000 0001 0000 0000]
[in]	Mode	[0 - Input, 1 - Output, 2 - Alternate, 3 - Analog]
