Enumeration Type Documentation

gpio_int_level_en

enum gpio_int_level_en

Interrupt level or edge selection.

Enumerator
GPIO_INT_LEVEL_LOW	Low level or falling edge
GPIO_INT_LEVEL_HIGH	High level or rising edge

gpio_status_en

enum gpio_status_en

Return status for GPIO driver.

This enumeration defines various return and error codes used by the GPIO driver to indicate success, failure, and specific error conditions.

Enumerator
GPIO_OK	Operation succeeded
GPIO_ERROR	Unspecified error
GPIO_ERROR_BUSY	Driver is busy
GPIO_ERROR_TIMEOUT	Timeout occurred
GPIO_ERROR_UNSUPPORTED	Operation not supported
GPIO_ERROR_PARAMETER	Parameter error
GPIO_ERROR_INVALID_CONFIG	Invalid Configuration
GPIO_ERROR_INITIALIZED	GPIO device was previously initialized
GPIO_ERROR_ALL_PINS_UNAVAILABLE	All pins are unavailable
GPIO_ERROR_PIN_NOT_IN_USE	Write/read to pin that isn't in use
GPIO_ERROR_PINS_MUX_NOT_GPIO	Pin/pins current mux-function isn't GPIO
GPIO_ERROR_ILLEGAL_DIRECTION	Pin/pins current mux-function allows pin to be in one direction - GPI/GPO
GPIO_ERROR_PIN_NOT_IN_PORT	Pin not in particular port
GPIO_ERROR_NOT_OUTPUT	Pin is not an output pin
