- ##### Callback registration ##### - ================================== - - [..] - The compilation define USE_HAL_IRDA_REGISTER_CALLBACKS when set to 1 - allows the user to configure dynamically the driver callbacks. - - [..] - Use Function @ref HAL_IRDA_RegisterCallback() to register a user callback. - Function @ref HAL_IRDA_RegisterCallback() allows to register following callbacks: - (+) TxHalfCpltCallback : Tx Half Complete Callback. - (+) TxCpltCallback : Tx Complete Callback. - (+) RxHalfCpltCallback : Rx Half Complete Callback. - (+) RxCpltCallback : Rx Complete Callback. - (+) ErrorCallback : Error Callback. - (+) AbortCpltCallback : Abort Complete Callback. - (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. - (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. - (+) MspInitCallback : IRDA MspInit. - (+) MspDeInitCallback : IRDA MspDeInit. - This function takes as parameters the HAL peripheral handle, the Callback ID - and a pointer to the user callback function. - - [..] - Use function @ref HAL_IRDA_UnRegisterCallback() to reset a callback to the default - weak (surcharged) function. - @ref HAL_IRDA_UnRegisterCallback() takes as parameters the HAL peripheral handle, - and the Callback ID. - This function allows to reset following callbacks: - (+) TxHalfCpltCallback : Tx Half Complete Callback. - (+) TxCpltCallback : Tx Complete Callback. - (+) RxHalfCpltCallback : Rx Half Complete Callback. - (+) RxCpltCallback : Rx Complete Callback. - (+) ErrorCallback : Error Callback. - (+) AbortCpltCallback : Abort Complete Callback. - (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. - (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. - (+) MspInitCallback : IRDA MspInit. - (+) MspDeInitCallback : IRDA MspDeInit. - - [..] - By default, after the @ref HAL_IRDA_Init() and when the state is HAL_IRDA_STATE_RESET - all callbacks are set to the corresponding weak (surcharged) functions: - examples @ref HAL_IRDA_TxCpltCallback(), @ref HAL_IRDA_RxHalfCpltCallback(). - Exception done for MspInit and MspDeInit functions that are respectively - reset to the legacy weak (surcharged) functions in the @ref HAL_IRDA_Init() - and @ref HAL_IRDA_DeInit() only when these callbacks are null (not registered beforehand). - If not, MspInit or MspDeInit are not null, the @ref HAL_IRDA_Init() and @ref HAL_IRDA_DeInit() - keep and use the user MspInit/MspDeInit callbacks (registered beforehand). - - [..] - Callbacks can be registered/unregistered in HAL_IRDA_STATE_READY state only. - Exception done MspInit/MspDeInit that can be registered/unregistered - in HAL_IRDA_STATE_READY or HAL_IRDA_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 @ref HAL_IRDA_RegisterCallback() before calling @ref HAL_IRDA_DeInit() - or @ref HAL_IRDA_Init() function. - - [..] - When The compilation define USE_HAL_IRDA_REGISTER_CALLBACKS is set to 0 or - not defined, the callback registration feature is not available - and weak (surcharged) callbacks are used. - - @endverbatim - ****************************************************************************** -
