	Initialize GPIO_out instance.

GPIO output handling.

Note

Define LOGIC_OUT_IT shared symbol at project level to use GPIO_out from timer interrupts (for more timing precision if required)

When using GPIO_out from interrupts, shared LOGIC_OUT_IT_PER period is defined by default with a period of 1000µs (can be customly defined)

Warning

Logic_out & GPIO_out shares interrupt behavior, thus needs to be implemented the same way (it or loop) if both are used at the same time

Function Documentation

GPIO_out_init()

FctERR GPIO_out_init	(	GPIO_out *const	out,
		GPIO_TypeDef *const	GPIOx,
		const uint16_t	GPIO_Pin,
		const GPIO_PinState	polarity )

Initialize GPIO_out instance.

Parameters

[in,out]	out	- GPIO_out instance to initialize
[in]	GPIOx	- port to write to
[in]	GPIO_Pin	- pin to write to
[in]	polarity	- set to GPIO_PIN_RESET if active state is GND, GPIO_PIN_SET if Vdd

Returns

FctERR - Error code
