HAL GPIO mode constants

HAL1

HAL2

The GPIO mode is configured through predefined constants.

The GPIO mode and output type are specified independently using separate enumerations: hal_gpio_mode_t and hal_gpio_output_t, respectively. 



#define  GPIO_MODE_INPUT
#define  GPIO_MODE_OUTPUT_PP
#define  GPIO_MODE_OUTPUT_OD
#define  GPIO_MODE_AF_PP
#define  GPIO_MODE_AF_OD
#define  GPIO_MODE_ANALOG

typedef enum
{
  HAL_GPIO_MODE_INPUT,
  HAL_GPIO_MODE_OUTPUT,

  HAL_GPIO_MODE_ALTERNATE,

  HAL_GPIO_MODE_ANALOG
} hal_gpio_mode_t;

typedef enum
{
  HAL_GPIO_OUTPUT_PUSHPULL,
  HAL_GPIO_OUTPUT_OPENDRAIN
} hal_gpio_output_t;

HAL GPIO trigger mode constants

HAL1

HAL2

The GPIO trigger mode is configured through predefined constants.

The EXTI mode and trigger are defined separately using distinct enumerations hal_exti_mode_t and hal_exti_trigger_t in HAL EXTI driver. 



#define  GPIO_MODE_IT_RISING
#define  GPIO_MODE_EVT_RISING
#define  GPIO_MODE_IT_FALLING
#define  GPIO_MODE_EVT_FALLING
#define  GPIO_MODE_IT_RISING_FALLING
#define  GPIO_MODE_EVT_RISING_FALLING

typedef enum
{
  HAL_EXTI_TRIGGER_NONE,
  HAL_EXTI_TRIGGER_RISING,

  HAL_EXTI_TRIGGER_FALLING,

  HAL_EXTI_TRIGGER_RISING_FALLING

} hal_exti_trigger_t;

typedef enum
{
  HAL_EXTI_MODE_INTERRUPT,
  HAL_EXTI_MODE_EVENT
  HAL_EXTI_MODE_INTERRUPT_EVENT
} hal_exti_mode_t;
