Function Documentation

GPIO_in_init()

void GPIO_in_init	(	GPIO_in *const	in,
		GPIO_TypeDef *const	GPIOx,
		const uint16_t	GPIO_Pin,
		const GPIO_PinState	polarity,
		const uint16_t	filter,
		void(*	onSet )(const GPIO_in *const),
		void(*	onReset )(const GPIO_in *const),
		const bool	repeat )

Initialize GPIO_in instance.

Parameters

[in,out]	in	- GPIO_in instance to initialize
[in]	GPIOx	- port to read from
[in]	GPIO_Pin	- pin to read from
[in]	polarity	- set to GPIO_PIN_RESET if active state is GND, GPIO_PIN_SET if Vdd
[in]	filter	- input filtering time
[in]	onSet	- Pointer to callback ON function
[in]	onReset	- Pointer to callback OFF function
[in]	repeat	- To repeat callback ON as long as input is set
