(+) @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. - - - *** I2C Workarounds linked to Silicon Limitation *** - ==================================================== - [..] - Below the list of all silicon limitations implemented for HAL on STM32F1xx product. - (@) See ErrataSheet to know full silicon limitation list of your product. - - (+) Workarounds Implemented inside I2C HAL Driver - (++) Wrong data read into data register (Polling and Interrupt mode) - (++) Start cannot be generated after a misplaced Stop - (++) Some software events must be managed before the current byte is being transferred: - Workaround: Use DMA in general, except when the Master is receiving a single byte. - For Interupt mode, I2C should have the highest priority in the application. - (++) Mismatch on the "Setup time for a repeated Start condition" timing parameter: - Workaround: Reduce the frequency down to 88 kHz or use the I2C Fast-mode if - supported by the slave. - (++) Data valid time (tVD;DAT) violated without the OVR flag being set: - Workaround: If the slave device allows it, use the clock stretching mechanism - by programming NoStretchMode = I2C_NOSTRETCH_DISABLE in @ref HAL_I2C_Init. - - [..] - (@) You can refer to the I2C HAL driver header file for more useful macros - - @endverbatim - ****************************************************************************** -
