Function Documentation

nrfx_gpiote_channel_alloc()

nrfx_err_t nrfx_gpiote_channel_alloc	(	nrfx_gpiote_t const *	p_instance,

	)

Function for allocating a GPIOTE channel.

This function allocates the first unused GPIOTE channel from pool defined in NRFX_GPIOTE_APP_CHANNELS_MASK.

Note

Function is thread safe as it uses nrfx_flag32_alloc.

Routines that allocate and free the GPIOTE channels are independent from the rest of the driver. In particular, the driver does not need to be initialized when this function is called.

Parameters

[in]	p_instance	Pointer to the driver instance structure.
[out]	p_channel	Pointer to the GPIOTE channel that has been allocated.

Return values

NRFX_SUCCESS	The channel was successfully allocated.

	)

Function for freeing a GPIOTE channel.

This function frees a GPIOTE channel that was allocated using nrfx_gpiote_channel_alloc.

Note

Function is thread safe as it uses nrfx_flag32_free.

Routines that allocate and free the GPIOTE channels are independent from the rest of the driver. In particular, the driver does not need to be initialized when this function is called.

Parameters

[in]	p_instance	Pointer to the driver instance structure.

Function for configuring the specified input pin and input event/interrupt.

Prior to calling this function pin can be uninitialized or configured as input or output. However, following transitions and configurations are invalid and result in error returned by the function:

void nrfx_gpiote_set_task_trigger	(	nrfx_gpiote_t const *	p_instance,
		nrfx_gpiote_pin_t	pin
	)

Function for triggering the task SET manually.

Parameters

[in]	p_instance	Pointer to the driver instance structure.
[in]	pin	Pin number.

nrfx_gpiote_trigger_disable()

void nrfx_gpiote_trigger_disable	(	nrfx_gpiote_t const *	p_instance,
		nrfx_gpiote_pin_t	pin
	)

Function for disabling trigger for the given pin.

Parameters

[in]	p_instance	Pointer to the driver instance structure.
[in]	pin	Absolute pin number.

nrfx_gpiote_trigger_enable()

void nrfx_gpiote_trigger_enable	(	nrfx_gpiote_t const *	p_instance,
		nrfx_gpiote_pin_t	pin,
		bool	int_enable
	)

Function for enabling trigger for the given pin.

When GPIOTE event is used trigger can be enabled without enabling interrupt, e.g. for PPI.

Parameters

[in]	p_instance	Pointer to the driver instance structure.
[in]	pin	Absolute pin number.
[in]	int_enable	True to enable the interrupt. Must be true when sensing is used.

nrfx_gpiote_uninit()

void nrfx_gpiote_uninit

(

nrfx_gpiote_t const *

p_instance

)

Function for uninitializing the GPIOTE driver instance.

Parameters

[in]

p_instance

Pointer to the driver instance structure.
