Once the Rx message have been - read, the notification can be activated again. - - - *** Sleep mode *** - ================== - [..] - (#) The CAN peripheral can be put in sleep mode (low power), using - HAL_CAN_RequestSleep(). The sleep mode will be entered as soon as the - current CAN activity (transmission or reception of a CAN frame) will - be completed. - - (#) A notification can be activated to be informed when the sleep mode - will be entered. - - (#) It can be checked if the sleep mode is entered using - HAL_CAN_IsSleepActive(). - Note that the CAN state (accessible from the API HAL_CAN_GetState()) - is HAL_CAN_STATE_SLEEP_PENDING as soon as the sleep mode request is - submitted (the sleep mode is not yet entered), and become - HAL_CAN_STATE_SLEEP_ACTIVE when the sleep mode is effective. - - (#) The wake-up from sleep mode can be triggered by two ways: - (++) Using HAL_CAN_WakeUp(). When returning from this function, - the sleep mode is exited (if return status is HAL_OK). - (++) When a start of Rx CAN frame is detected by the CAN peripheral, - if automatic wake up mode is enabled. - - *** Callback registration *** - ============================================= - - The compilation define USE_HAL_CAN_REGISTER_CALLBACKS when set to 1 - allows the user to configure dynamically the driver callbacks. - Use Function HAL_CAN_RegisterCallback() to register an interrupt callback. - - Function HAL_CAN_RegisterCallback() allows to register following callbacks: - (+) TxMailbox0CompleteCallback : Tx Mailbox 0 Complete Callback. - (+) TxMailbox1CompleteCallback : Tx Mailbox 1 Complete Callback. - (+) TxMailbox2CompleteCallback : Tx Mailbox 2 Complete Callback. - (+) TxMailbox0AbortCallback : Tx Mailbox 0 Abort Callback. - (+) TxMailbox1AbortCallback : Tx Mailbox 1 Abort Callback. - (+) TxMailbox2AbortCallback : Tx Mailbox 2 Abort Callback. - (+) RxFifo0MsgPendingCallback : Rx Fifo 0 Message Pending Callback. - (+) RxFifo0FullCallback : Rx Fifo 0 Full Callback. - (+) RxFifo1MsgPendingCallback : Rx Fifo 1 Message Pending Callback. - (+) RxFifo1FullCallback : Rx Fifo 1 Full Callback. - (+) SleepCallback : Sleep Callback. - (+) WakeUpFromRxMsgCallback : Wake Up From Rx Message Callback. - (+) ErrorCallback : Error Callback. - (+) MspInitCallback : CAN MspInit. - (+) MspDeInitCallback : CAN MspDeInit. - This function takes as parameters the HAL peripheral handle, the Callback ID - and a pointer to the user callback function. - - Use function HAL_CAN_UnRegisterCallback() to reset a callback to the default - weak function. - HAL_CAN_UnRegisterCallback takes as parameters the HAL peripheral handle, - and the Callback ID. - This function allows to reset following callbacks: - (+) TxMailbox0CompleteCallback : Tx Mailbox 0 Complete Callback. - (+) TxMailbox1CompleteCallback : Tx Mailbox 1 Complete Callback. - (+) TxMailbox2CompleteCallback : Tx Mailbox 2 Complete Callback. - (+) TxMailbox0AbortCallback : Tx Mailbox 0 Abort Callback. - (+) TxMailbox1AbortCallback : Tx Mailbox 1 Abort Callback. - (+) TxMailbox2AbortCallback : Tx Mailbox 2 Abort Callback. - (+) RxFifo0MsgPendingCallback : Rx Fifo 0 Message Pending Callback. - (+) RxFifo0FullCallback : Rx Fifo 0 Full Callback. - (+) RxFifo1MsgPendingCallback : Rx Fifo 1 Message Pending Callback. - (+) RxFifo1FullCallback : Rx Fifo 1 Full Callback. - (+) SleepCallback : Sleep Callback. - (+) WakeUpFromRxMsgCallback : Wake Up From Rx Message Callback. - (+) ErrorCallback : Error Callback. - (+) MspInitCallback : CAN MspInit. - (+) MspDeInitCallback : CAN MspDeInit. - - By default, after the HAL_CAN_Init() and when the state is HAL_CAN_STATE_RESET, - all callbacks are set to the corresponding weak functions: - example HAL_CAN_ErrorCallback(). - Exception done for MspInit and MspDeInit functions that are - reset to the legacy weak function in the HAL_CAN_Init()/ HAL_CAN_DeInit() only when - these callbacks are null (not registered beforehand). - if not, MspInit or MspDeInit are not null, the HAL_CAN_Init()/ HAL_CAN_DeInit() - keep and use the user MspInit/MspDeInit callbacks (registered beforehand) - - Callbacks can be registered/unregistered in HAL_CAN_STATE_READY state only. - Exception done MspInit/MspDeInit that can be registered/unregistered - in HAL_CAN_STATE_READY or HAL_CAN_STATE_RESET state, - thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. - In that case first register the MspInit/MspDeInit user callbacks - using HAL_CAN_RegisterCallback() before calling HAL_CAN_DeInit() - or HAL_CAN_Init() function. - - When The compilation define USE_HAL_CAN_REGISTER_CALLBACKS is set to 0 or - not defined, the callback registration feature is not available and all callbacks - are set to the corresponding weak functions. - - @endverbatim -
