Function Documentation

SPP_HAL_GPIO_configInterrupt()

SPP_RetVal_t SPP_HAL_GPIO_configInterrupt	(	spp_uint32_t	pin,
		spp_uint32_t	intrType,
		spp_uint32_t	pull )

Configure a GPIO pin as an interrupt input.

Parameters

[in]	pin	GPIO pin number.
[in]	intrType	Platform-specific interrupt trigger type value.
[in]	pull	Pull resistor: 0 = none, 1 = pull-up, 2 = pull-down.

Returns

K_SPP_OK on success.

SPP_HAL_GPIO_registerIsr()

SPP_RetVal_t SPP_HAL_GPIO_registerIsr	(	spp_uint32_t	pin,
		void *	p_isrCtx )

Register an ISR handler for a GPIO pin.

The ISR sets *p_isrCtx->p_flag to SPP_TRUE whenever the configured interrupt fires.

Parameters

[in]	pin	GPIO pin number.
[in]	p_isrCtx	Pointer to a SPP_GpioIsrCtx_t for this pin.

Returns

K_SPP_OK on success.
