__HAL_I2C_ENABLE: Enable the I2C peripheral + (+) __HAL_I2C_DISABLE: Disable the I2C peripheral + (+) __HAL_I2C_GENERATE_NACK: Generate a Non-Acknowledge I2C peripheral in Slave mode + (+) __HAL_I2C_GET_FLAG: Check whether the specified I2C flag is set or not + (+) __HAL_I2C_CLEAR_FLAG: Clear the specified I2C pending flag + (+) __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

driver ##### + ============================================================================== + [..] + (#) Enable and configure the peripheral to be connected to the MDMA Channel + (except for internal SRAM/FLASH memories: no initialization is + necessary) please refer to Reference manual for connection between peripherals + and MDMA requests. + + (#) + For a given Channel use HAL_MDMA_Init function to program the required configuration through the following parameters: + transfer request , channel priority, data endianness, Source increment, destination increment , + source data size, destination data size, data alignment, source Burst, destination Burst , + buffer Transfer Length, Transfer Trigger Mode (buffer transfer, block transfer, repeated block transfer + or full transfer) source and destination block address offset, mask address and data. + + If using the MDMA in linked list mode then use function HAL_MDMA_LinkedList_CreateNode to fill a transfer node. + Note that parameters given to the function HAL_MDMA_Init corresponds always to the node zero. + Use function HAL_MDMA_LinkedList_AddNode to connect the created node to the linked list at a given position. + User can make a linked list circular using function HAL_MDMA_LinkedList_EnableCircularMode , this function will automatically connect the + last node of the list to the first one in order to make the list circular. + In this case the linked list will loop on node 1 : first node connected after the initial transfer defined by the HAL_MDMA_Init + + -@- The initial transfer itself (node 0 corresponding to the Init). + User can disable the circular mode using function HAL_MDMA_LinkedList_DisableCircularMode, this function will then remove + the connection between last node and first one. + + Function HAL_MDMA_LinkedList_RemoveNode can be used to remove (disconnect) a node from the transfer linked list. + When a linked list is circular (last node connected to first one), if removing node1 (node where the linked list loops), + the linked list remains circular and node 2 becomes the first one. + Note that if the linked list is made circular the transfer will loop infinitely (or until aborted by the user). + + [..] + (+) User can select the transfer trigger mode (parameter TransferTriggerMode) to define the amount of data to be + transfer upon a request : + (++) MDMA_BUFFER_TRANSFER : each request triggers a transfer of BufferTransferLength data + with BufferTransferLength defined within the HAL_MDMA_Init. + (++) MDMA_BLOCK_TRANSFER : each request triggers a transfer of a block + with block size defined within the function HAL_MDMA_Start/HAL_MDMA_Start_IT + or within the current linked list node parameters. + (++) MDMA_REPEAT_BLOCK_TRANSFER : each request triggers a transfer of a number of blocks + with block size and number of blocks defined within the function HAL_MDMA_Start/HAL_MDMA_Start_IT + or within the current linked list node parameters. + (++) MDMA_FULL_TRANSFER : each request triggers a full transfer + all blocks and all nodes(if a linked list has been created using HAL_MDMA_LinkedList_CreateNode \ HAL_MDMA_LinkedList_AddNode). + + *** Polling mode IO operation *** + ================================= + [..] + (+) Use HAL_MDMA_Start() to start MDMA transfer after the configuration of Source + address and destination address and the Length of data to be transferred. + (+) Use HAL_MDMA_PollForTransfer() to poll for the end of current transfer or a transfer level + In this case a fixed Timeout can be configured by User depending from his application. + (+) Use HAL_MDMA_Abort() function to abort the current transfer : blocking method this API returns + when the abort ends or timeout (should not be called from an interrupt service routine). + + *** Interrupt mode IO operation *** + =================================== + [..] + (+) Configure the MDMA interrupt priority using HAL_NVIC_SetPriority() + (+) Enable the MDMA IRQ handler using HAL_NVIC_EnableIRQ() + (+) Use HAL_MDMA_Start_IT() to start MDMA transfer after the configuration of + Source address and destination address and the Length of data to be transferred. In this + case the MDMA interrupt is configured. + (+) Use HAL_MDMA_IRQHandler() called under MDMA_IRQHandler() Interrupt subroutine + (+) At the end of data transfer HAL_MDMA_IRQHandler() function is executed and user can + add his own function by customization of function pointer XferCpltCallback and + XferErrorCallback (i.e a member of MDMA handle structure). + + (+) Use HAL_MDMA_Abort_IT() function to abort the current transfer : non-blocking method. This API will finish the execution immediately + then the callback XferAbortCallback (if specified by the user) is asserted once the MDMA channel has effectively aborted. + (could be called from an interrupt service routine). + + (+) Use functions HAL_MDMA_RegisterCallback and HAL_MDMA_UnRegisterCallback respectevely to register unregister user callbacks + from the following list : + (++) XferCpltCallback : transfer complete callback. + (++) XferBufferCpltCallback : buffer transfer complete callback. + (++) XferBlockCpltCallback : block transfer complete callback. + (++) XferRepeatBlockCpltCallback : repeated block transfer complete callback. + (++) XferErrorCallback : transfer error callback. + (++) XferAbortCallback : transfer abort complete callback. + + [..] + (+) If the transfer Request corresponds to SW request (MDMA_REQUEST_SW) User can use function HAL_MDMA_GenerateSWRequest to + trigger requests manually. Function HAL_MDMA_GenerateSWRequest must be used with the following precautions: + (++) This function returns an error if used while the Transfer has ended or not started. + (++) If used while the current request has not been served yet (current request transfer on going) + this function returns an error and the new request is ignored. + + Generally this function should be used in conjunctions with the MDMA callbacks: + (++) example 1: + (+++) Configure a transfer with request set to MDMA_REQUEST_SW and trigger mode set to MDMA_BUFFER_TRANSFER + (+++) Register a callback for buffer transfer complete (using callback ID set to HAL_MDMA_XFER_BUFFERCPLT_CB_ID) + (+++) After calling HAL_MDMA_Start_IT the MDMA will issue the transfer of a first BufferTransferLength data. + (+++) When the buffer transfer complete callback is asserted first buffer has been transferred and user can ask for a new buffer transfer + request using HAL_MDMA_GenerateSWRequest. + + (++) example 2: + (+++) Configure a transfer with request set to MDMA_REQUEST_SW and trigger mode set to MDMA_BLOCK_TRANSFER + (+++) Register a callback for block transfer complete (using callback ID HAL_MDMA_XFER_BLOCKCPLT_CB_ID) + (+++) After calling HAL_MDMA_Start_IT the MDMA will issue the transfer of a first block of data. + (+++) When the block transfer complete callback is asserted the first block has been transferred and user can ask + for a new block transfer request using HAL_MDMA_GenerateSWRequest. + + [..] Use HAL_MDMA_GetState() function to return the MDMA state and HAL_MDMA_GetError() in case of error detection. + + *** MDMA HAL driver macros list *** + ============================================= + [..] + Below the list of most used macros in MDMA HAL driver. + + (+) __HAL_MDMA_ENABLE: Enable the specified MDMA Channel. + (+) __HAL_MDMA_DISABLE: Disable the specified MDMA Channel. + (+) __HAL_MDMA_GET_FLAG: Get the MDMA Channel pending flags. + (+) __HAL_MDMA_CLEAR_FLAG: Clear the MDMA Channel pending flags. + (+) __HAL_MDMA_ENABLE_IT: Enable the specified MDMA Channel interrupts. + (+) __HAL_MDMA_DISABLE_IT: Disable the specified MDMA Channel interrupts. + (+) __HAL_MDMA_GET_IT_SOURCE: Check whether the specified MDMA Channel interrupt has occurred or not. + + [..] + (@) You can refer to the header file of the MDMA HAL driver for more useful macros. + + [..] + + @endverbatim + */ + +/* Includes ------------------------------------------------------------------*/ +#include "stm32h7xx_hal.h" + +/** @addtogroup STM32H7xx_HAL_Driver + * @{ + */ + +/** @defgroup MDMA MDMA + * @brief MDMA HAL module driver + * @{ + */ + +#ifdef HAL_MDMA_MODULE_ENABLED + +/* Private typedef -----------------------------------------------------------*/ +/* Private constants ---------------------------------------------------------*/ +/** @addtogroup MDMA_Private_Constants + * @{ + */ +#define HAL_TIMEOUT_MDMA_ABORT 5U /* 5 ms */ +#define HAL_MDMA_CHANNEL_SIZE 0x40U /* an MDMA instance channel size is 64 byte */ +/** + * @} + */ +/* Private macro -------------------------------------------------------------*/ +/* Private variables ---------------------------------------------------------*/ +/* Private function prototypes -----------------------------------------------*/ +/** @addtogroup MDMA_Private_Functions_Prototypes + * @{ + */ +static void MDMA_SetConfig(MDMA_HandleTypeDef *hmdma, uint32_t SrcAddress, uint32_t DstAddress, uint32_t BlockDataLength, uint32_t BlockCount);

It uses the FMC layer functions to interface + with NOR devices. This driver is used as follows: + + (+) NOR flash memory configuration sequence using the function HAL_NOR_Init() + with control and timing parameters for both normal and extended mode. + + (+) Read NOR flash memory manufacturer code and device IDs using the function + HAL_NOR_Read_ID(). The read information is stored in the NOR_ID_TypeDef + structure declared by the function caller. + + (+) Access NOR flash memory by read/write data unit operations using the functions + HAL_NOR_Read(), HAL_NOR_Program(). + + (+) Perform NOR flash erase block/chip operations using the functions + HAL_NOR_Erase_Block() and HAL_NOR_Erase_Chip(). + + (+) Read the NOR flash CFI (common flash interface) IDs using the function + HAL_NOR_Read_CFI(). The read information is stored in the NOR_CFI_TypeDef + structure declared by the function caller. + + (+) You can also control the NOR device by calling the control APIs HAL_NOR_WriteOperation_Enable()/ + HAL_NOR_WriteOperation_Disable() to respectively enable/disable the NOR write operation + + (+) You can monitor the NOR device HAL state by calling the function + HAL_NOR_GetState() + [..] + (@) This driver is a set of generic APIs which handle standard NOR flash operations. + If a NOR flash device contains different operations and/or implementations, + it should be implemented separately. + + *** NOR HAL driver macros list *** + ============================================= + [..] + Below the list of most used macros in NOR HAL driver. + + (+) NOR_WRITE : NOR memory write data to specified address + + *** Callback registration *** + ============================================= + [..] + The compilation define USE_HAL_NOR_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + + Use Functions HAL_NOR_RegisterCallback() to register a user callback, + it allows to register following callbacks: + (+) MspInitCallback : NOR MspInit. + (+) MspDeInitCallback : NOR MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + Use function HAL_NOR_UnRegisterCallback() to reset a callback to the default + weak (overridden) function. It allows to reset following callbacks: + (+) MspInitCallback : NOR MspInit. + (+) MspDeInitCallback : NOR MspDeInit. + This function) takes as parameters the HAL peripheral handle and the Callback ID. + + By default, after the HAL_NOR_Init and if the state is HAL_NOR_STATE_RESET + all callbacks are reset to the corresponding legacy weak (overridden) functions. + Exception done for MspInit and MspDeInit callbacks that are respectively + reset to the legacy weak (overridden) functions in the HAL_NOR_Init + and HAL_NOR_DeInit only when these callbacks are null (not registered beforehand). + If not, MspInit or MspDeInit are not null, the HAL_NOR_Init and HAL_NOR_DeInit + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) + + Callbacks can be registered/unregistered in READY state only. + Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered + in READY or 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_NOR_RegisterCallback before calling HAL_NOR_DeInit + or HAL_NOR_Init function. + + When The compilation define USE_HAL_NOR_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registering feature is not available + and weak (overridden) callbacks are used. + + @endverbatim +
