NMI_API sint8 m2m_periph_gpio_get_val	(	uint8	u8GpioNum,
		uint8 *	pu8GpioVal
	)

Read an WINC15x0 GPIO input level.

Parameters

[in]	u8GpioNum	GPIO number. Allowed values are defined in tenuGpioNum.
[out]	pu8GpioVal	GPIO input value. Zero = low, non-zero = high.

Returns

The function returns M2M_SUCCESS for success and a negative value otherwise.

NMI_API sint8 m2m_periph_gpio_set_dir	(	uint8	u8GpioNum,
		uint8	u8GpioDir
	)

Configure a specific WINC15x0 pad as a GPIO and sets its direction (input or output).

Parameters

[in]	u8GpioNum	GPIO number. Allowed values are defined in tenuGpioNum.
[in]	u8GpioDir	GPIO direction: Zero = input. Non-zero = output.

Returns

The function returns M2M_SUCCESS for success and a negative value otherwise.

NMI_API sint8 m2m_periph_gpio_set_val	(	uint8	u8GpioNum,
		uint8	u8GpioVal
	)

Set an WINC15x0 GPIO output level high or low.

Parameters

[in]	u8GpioNum	GPIO number. Allowed values are defined in tenuGpioNum.
[in]	u8GpioVal	GPIO output value. Zero = low, non-zero = high.

Returns

The function SHALL return 0 for success and a negative value otherwise.

NMI_API sint8 m2m_periph_pullup_ctrl	(	uint32	pinmask,
		uint8	enable
	)

Control the programmable pull-up resistor on the chip pads .

Parameters

[in]	pinmask	Write operation bitwise-ORed mask for which pads to control. Allowed values are defined in tenuPullupMask.
[in]	enable	Set to 0 to disable pull-up resistor. Non-zero will enable the pull-up.

Returns

The function returns M2M_SUCCESS for success and a negative value otherwise.
