Function Documentation

hal_gpio_deinit()

void hal_gpio_deinit	(	gpio_regs_t *	GPIOx,
		uint32_t	gpio_pin
	)

De-initialize the GPIOx peripheral registers to their default reset values.

Parameters

[in]	GPIOx	Where x can be (0, 1) to select the GPIO peripheral port for GR55xx device
[in]	gpio_pin	Specifies the port bit to be written. This parameter can be a combiantion of the following values: GPIO_PIN_0 GPIO_PIN_1 GPIO_PIN_2 GPIO_PIN_3 GPIO_PIN_4 GPIO_PIN_5 GPIO_PIN_6 GPIO_PIN_7 GPIO_PIN_8 GPIO_PIN_9 GPIO_PIN_10 GPIO_PIN_11 GPIO_PIN_12 GPIO_PIN_13 GPIO_PIN_14 GPIO_PIN_15 GPIO_PIN_ALL

hal_gpio_init()

void hal_gpio_init	(	gpio_regs_t *	GPIOx,
		gpio_init_t *	p_gpio_init
	)

Initialize the GPIOx peripheral according to the specified parameters in the p_gpio_init.

Parameters

[in]	GPIOx	Where x can be (0, 1) to select the GPIO peripheral port
[in]	p_gpio_init	Pointer to a gpio_init_t structure that contains the configuration information for the specified GPIO peripheral port.
