Function Documentation

HAL_CAN_ActivateNotification()

HAL_StatusTypeDef HAL_CAN_ActivateNotification	(	CAN_HandleTypeDef *	hcan,
		uint32_t	ActiveITs )

#include <stm32f4xx_hal_can.h>

Enable interrupts.

Parameters

hcan	pointer to an CAN_HandleTypeDef structure that contains the configuration information for the specified CAN.
ActiveITs	indicates which interrupts will be enabled. This parameter can be any combination of CAN_Interrupts.
