Data Structure Documentation

struct gpio_pin_config_t

Each pin can only be configured as either an output pin or an input pin at a time. If configured as an input pin, leave the outputConfig unused. Note that in some use cases, the corresponding port property should be configured in advance with the PORT_SetPinConfig().

Data Fields
gpio_pin_direction_t	pinDirection
	GPIO direction, input or output.
uint8_t	outputLogic
	Set a default output logic, which has no use in input.
