HAL EXTI types migration ¶

This section provides information about the HAL EXTI types migration .

HAL EXTI callback ID type definition ¶

HAL1	HAL2
typedef enum { HAL_EXTI_COMMON_CB_ID, HAL_EXTI_RISING_CB_ID, HAL_EXTI_FALLING_CB_ID, } EXTI_CallbackIDTypeDef;	Removed; the callback registration in HAL2 is managed by `HAL_EXTI_RegisterTriggerCallback` function

HAL EXTI handle type definition ¶

HAL1	HAL2
EXTI_HandleTypeDef;	hal_exti_handle_t;

HAL EXTI configuration type definition ¶

In HAL2, the line is directly passed as a parameter to the HAL_EXTI_Init() function, and the mode is specified separately as the second parameter in the HAL_EXTI_Enable() function.

HAL1	HAL2
typedef struct { uint32_t Line; uint32_t Mode; uint32_t Trigger; uint32_t GPIOSel; } EXTI_ConfigTypeDef;	typedef struct { /Moved to hal_exti_line_t enum/ /Moved to hal_exti_mode_t enum/ hal_exti_trigger_t trigger; hal_exti_gpio_port_t gpio_port; } hal_exti_config_t;

HAL1

HAL2

                typedef struct
 {
 uint32_t Line;
 uint32_t Mode;
 uint32_t Trigger;
 uint32_t GPIOSel;

                typedef struct

 /*Moved to hal_exti_line_t enum*/
 /*Moved to hal_exti_mode_t enum*/
