NMI_API sint8 m2m_periph_gpio_get_val ( uint8  u8GpioNum,
uint8 pu8GpioVal 
)

Read an WINC15x0 GPIO input level.

Parameters
[in]u8GpioNumGPIO number. Allowed values are defined in tenuGpioNum.
[out]pu8GpioValGPIO 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]u8GpioNumGPIO number. Allowed values are defined in tenuGpioNum.
[in]u8GpioDirGPIO 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]u8GpioNumGPIO number. Allowed values are defined in tenuGpioNum.
[in]u8GpioValGPIO 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]pinmaskWrite operation bitwise-ORed mask for which pads to control. Allowed values are defined in tenuPullupMask.
[in]enableSet 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.
