(+) __HAL_I2C_ENABLE_IT: Enable the specified I2C interrupt - (+) __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 HAL_I2C_RegisterCallback() or HAL_I2C_RegisterAddrCallback() - to register an interrupt callback. - [..] - Function 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 : HAL_I2C_RegisterAddrCallback(). - [..] - Use function HAL_I2C_UnRegisterCallback to reset a callback to the default - weak function. - 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 : HAL_I2C_UnRegisterAddrCallback(). - [..] - By default, after the HAL_I2C_Init() and when the state is HAL_I2C_STATE_RESET - all callbacks are set to the corresponding weak functions: - examples HAL_I2C_MasterTxCpltCallback(), HAL_I2C_MasterRxCpltCallback(). - Exception done for MspInit and MspDeInit functions that are - reset to the legacy weak functions in the HAL_I2C_Init()/ HAL_I2C_DeInit() only when - these callbacks are null (not registered beforehand). - If MspInit or MspDeInit are not null, the HAL_I2C_Init()/ HAL_I2C_DeInit() - keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state. - [..] - Callbacks can be registered/unregistered in HAL_I2C_STATE_READY state only. - Exception done MspInit/MspDeInit functions that can be registered/unregistered - in HAL_I2C_STATE_READY or 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 HAL_I2C_RegisterCallback() before calling HAL_I2C_DeInit() - or 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 -

[..] - This subsection provides a set of functions allowing to manage the I2C data - transfers. - - (#) There are two modes of transfer: - (++) Blocking mode : The communication is performed in the polling mode. - The status of all data processing is returned by the same function - after finishing transfer. - (++) No-Blocking mode : The communication is performed using Interrupts - or DMA. These functions return the status of the transfer startup. - The end of the data processing will be indicated through the - dedicated I2C IRQ when using Interrupt mode or the DMA IRQ when - using DMA mode. - - (#) Blocking mode functions are : - (++) HAL_I2C_Master_Transmit() - (++) HAL_I2C_Master_Receive() - (++) HAL_I2C_Slave_Transmit() - (++) HAL_I2C_Slave_Receive() - (++) HAL_I2C_Mem_Write() - (++) HAL_I2C_Mem_Read() - (++) HAL_I2C_IsDeviceReady() - - (#) No-Blocking mode functions with Interrupt are : - (++) HAL_I2C_Master_Transmit_IT() - (++) HAL_I2C_Master_Receive_IT() - (++) HAL_I2C_Slave_Transmit_IT() - (++) HAL_I2C_Slave_Receive_IT() - (++) HAL_I2C_Mem_Write_IT() - (++) HAL_I2C_Mem_Read_IT() - (++) HAL_I2C_Master_Seq_Transmit_IT() - (++) HAL_I2C_Master_Seq_Receive_IT() - (++) HAL_I2C_Slave_Seq_Transmit_IT() - (++) HAL_I2C_Slave_Seq_Receive_IT() - (++) HAL_I2C_EnableListen_IT() - (++) HAL_I2C_DisableListen_IT() - (++) HAL_I2C_Master_Abort_IT() - - (#) No-Blocking mode functions with DMA are : - (++) HAL_I2C_Master_Transmit_DMA() - (++) HAL_I2C_Master_Receive_DMA() - (++) HAL_I2C_Slave_Transmit_DMA() - (++) HAL_I2C_Slave_Receive_DMA() - (++) HAL_I2C_Mem_Write_DMA() - (++) HAL_I2C_Mem_Read_DMA() - (++) HAL_I2C_Master_Seq_Transmit_DMA() - (++) HAL_I2C_Master_Seq_Receive_DMA() - (++) HAL_I2C_Slave_Seq_Transmit_DMA() - (++) HAL_I2C_Slave_Seq_Receive_DMA() - - (#) A set of Transfer Complete Callbacks are provided in non Blocking mode: - (++) HAL_I2C_MasterTxCpltCallback() - (++) HAL_I2C_MasterRxCpltCallback() - (++) HAL_I2C_SlaveTxCpltCallback() - (++) HAL_I2C_SlaveRxCpltCallback() - (++) HAL_I2C_MemTxCpltCallback() - (++) HAL_I2C_MemRxCpltCallback() - (++) HAL_I2C_AddrCallback() - (++) HAL_I2C_ListenCpltCallback() - (++) HAL_I2C_ErrorCallback() - (++) HAL_I2C_AbortCpltCallback() - -@endverbatim - * @{ - */ - -/** - * @brief Transmits in master mode an amount of data in blocking mode. - * @param hi2c Pointer to a I2C_HandleTypeDef structure that contains - * the configuration information for the specified I2C. - * @param DevAddress Target device address: The device 7 bits address value - * in datasheet must be shifted to the left before calling the interface - * @param pData Pointer to data buffer - * @param Size Amount of data to be sent - * @param Timeout Timeout duration - * @retval HAL status - */ -HAL_StatusTypeDef HAL_I2C_Master_Transmit(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint8_t *pData, - uint16_t Size, uint32_t Timeout) -{ - uint32_t tickstart;
