pointer @ref HAL_I2C_ErrorCallback() + + + *** I2C HAL driver macros list *** + ================================== + [..] + Below the list of most used macros in I2C HAL driver. + + (+) @ref __HAL_I2C_ENABLE: Enable the I2C peripheral + (+) @ref __HAL_I2C_DISABLE: Disable the I2C peripheral + (+) @ref __HAL_I2C_GENERATE_NACK: Generate a Non-Acknowledge I2C peripheral in Slave mode + (+) @ref __HAL_I2C_GET_FLAG: Check whether the specified I2C flag is set or not + (+) @ref __HAL_I2C_CLEAR_FLAG: Clear the specified I2C pending flag + (+) @ref __HAL_I2C_ENABLE_IT: Enable the specified I2C interrupt + (+) @ref __HAL_I2C_DISABLE_IT: Disable the specified I2C interrupt + + *** Callback registration *** + ============================================= + [..] + The compilation flag USE_HAL_I2C_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use Functions @ref HAL_I2C_RegisterCallback() or @ref HAL_I2C_RegisterAddrCallback() + to register an interrupt callback. + [..] + Function @ref HAL_I2C_RegisterCallback() allows to register following callbacks: + (+) MasterTxCpltCallback : callback for Master transmission end of transfer. + (+) MasterRxCpltCallback : callback for Master reception end of transfer. + (+) SlaveTxCpltCallback : callback for Slave transmission end of transfer. + (+) SlaveRxCpltCallback : callback for Slave reception end of transfer. + (+) ListenCpltCallback : callback for end of listen mode. + (+) MemTxCpltCallback : callback for Memory transmission end of transfer. + (+) MemRxCpltCallback : callback for Memory reception end of transfer. + (+) ErrorCallback : callback for error detection. + (+) AbortCpltCallback : callback for abort completion process. + (+) MspInitCallback : callback for Msp Init. + (+) MspDeInitCallback : callback for Msp DeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + [..] + For specific callback AddrCallback use dedicated register callbacks : @ref HAL_I2C_RegisterAddrCallback(). + [..] + Use function @ref HAL_I2C_UnRegisterCallback to reset a callback to the default + weak function. + @ref HAL_I2C_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) MasterTxCpltCallback : callback for Master transmission end of transfer. + (+) MasterRxCpltCallback : callback for Master reception end of transfer. + (+) SlaveTxCpltCallback : callback for Slave transmission end of transfer. + (+) SlaveRxCpltCallback : callback for Slave reception end of transfer. + (+) ListenCpltCallback : callback for end of listen mode. + (+) MemTxCpltCallback : callback for Memory transmission end of transfer. + (+) MemRxCpltCallback : callback for Memory reception end of transfer. + (+) ErrorCallback : callback for error detection. + (+) AbortCpltCallback : callback for abort completion process. + (+) MspInitCallback : callback for Msp Init. + (+) MspDeInitCallback : callback for Msp DeInit. + [..] + For callback AddrCallback use dedicated register callbacks : @ref HAL_I2C_UnRegisterAddrCallback(). + [..] + By default, after the @ref HAL_I2C_Init() and when the state is @ref HAL_I2C_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples @ref HAL_I2C_MasterTxCpltCallback(), @ref HAL_I2C_MasterRxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak functions in the @ref HAL_I2C_Init()/ @ref HAL_I2C_DeInit() only when + these callbacks are null (not registered beforehand). + If MspInit or MspDeInit are not null, the @ref HAL_I2C_Init()/ @ref HAL_I2C_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state. + [..] + Callbacks can be registered/unregistered in @ref HAL_I2C_STATE_READY state only. + Exception done MspInit/MspDeInit functions that can be registered/unregistered + in @ref HAL_I2C_STATE_READY or @ref HAL_I2C_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + Then, the user first registers the MspInit/MspDeInit user callbacks + using @ref HAL_I2C_RegisterCallback() before calling @ref HAL_I2C_DeInit() + or @ref HAL_I2C_Init() function. + [..] + When the compilation flag USE_HAL_I2C_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. + + [..] + (@) You can refer to the I2C HAL driver header file for more useful macros + + @endverbatim + ****************************************************************************** + *
