+ * This file provides firmware functions to manage the following

+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral Control functions
+ * + Peripheral State and Error functions

+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The sequence below describes how to use this driver to capture image
+ from a camera module connected to the DCMI Interface.
+ This sequence does not take into account the configuration of the
+ camera module, which should be made before to configure and enable
+ the DCMI to capture images.
+
+ (#) Program the required configuration through following parameters:
+ horizontal and vertical polarity, pixel clock polarity, Capture Rate,
+ Synchronization Mode, code of the frame delimiter and data width
+ using HAL_DCMI_Init() function.
+
+ (#) Configure the selected DMA stream to transfer Data from DCMI DR
+ register to the destination memory buffer.
+
+ (#) Program the required configuration through following parameters:
+ DCMI mode, destination memory Buffer address and the data length
+ and enable capture using HAL_DCMI_Start_DMA() function.
+
+ (#) Optionally, configure and Enable the CROP feature to select a rectangular
+ window from the received image using HAL_DCMI_ConfigCrop()
+ and HAL_DCMI_EnableCrop() functions
+
+ (#) The capture can be stopped using HAL_DCMI_Stop() function.
+
+ (#) To control DCMI state you can use the function HAL_DCMI_GetState().
+
+ *** Callback registration ***
+ =============================================
+
+ The compilation flag USE_HAL_DCMI_REGISTER_CALLBACKS when set to 1
+ allows the user to configure dynamically the driver callbacks.
+ Use Functions HAL_DCMI_RegisterCallback() to register an interrupt callback.
+
+ Function HAL_DCMI_RegisterCallback() allows to register following callbacks:
+ (+) LineEventCallback : callback for DCMI line event.
+ (+) FrameEventCallback : callback for DCMI Frame event.
+ (+) VsyncEventCallback : callback for DCMI Vsync event.
+ (+) ErrorCallback : callback for error detection.
+ (+) 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.
+
+ Use function HAL_DCMI_UnRegisterCallback to reset a callback to the default weak function.
+ HAL_DCMI_UnRegisterCallback takes as parameters the HAL peripheral handle and the Callback ID.
+ This function allows to reset following callbacks:
+ (+) LineEventCallback : callback for DCMI line event.
+ (+) FrameEventCallback : callback for DCMI Frame event.
+ (+) VsyncEventCallback : callback for DCMI Vsync event.
+ (+) ErrorCallback : callback for error detection.
+ (+) MspInitCallback : callback for Msp Init.
+ (+) MspDeInitCallback : callback for Msp DeInit.
+
+ By default, after the HAL_DCMI_Init() and when the state is HAL_DCMI_STATE_RESET
+ all callbacks are set to the corresponding weak functions:
+ examples HAL_DCMI_LineEventCallback(), HAL_DCMI_FrameEventCallback().
+ Exception done for MspInit and MspDeInit functions that are
+ reset to the legacy weak functions in the HAL_DCMI_Init()/ HAL_DCMI_DeInit() only when
+ these callbacks are null (not registered beforehand).
+ If MspInit or MspDeInit are not null, the HAL_DCMI_Init()/ HAL_DCMI_DeInit()
+ keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
+
+ Callbacks can be registered/unregistered in HAL_DCMI_STATE_READY state only.
+ Exception done MspInit/MspDeInit functions that can be registered/unregistered
+ in HAL_DCMI_STATE_READY or HAL_DCMI_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 HAL_DCMI_RegisterCallback() before calling HAL_DCMI_DeInit() or HAL_DCMI_Init() function.
+
+ When the compilation flag USE_HAL_DCMI_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.
+
+ *** DCMI HAL driver macros list ***
+ =============================================
+ [..]
+ Below the list of most used macros in DCMI HAL driver.
+
+ (+) __HAL_DCMI_ENABLE: Enable the DCMI peripheral.
+ (+) __HAL_DCMI_DISABLE: Disable the DCMI peripheral.
+ (+) __HAL_DCMI_GET_FLAG: Get the DCMI pending flags.
+ (+) __HAL_DCMI_CLEAR_FLAG: Clear the DCMI pending flags.
+ (+) __HAL_DCMI_ENABLE_IT: Enable the specified DCMI interrupts.
+ (+) __HAL_DCMI_DISABLE_IT: Disable the specified DCMI interrupts.
+ (+) __HAL_DCMI_GET_IT_SOURCE: Check whether the specified DCMI interrupt has occurred or not.
+
+ [..]
+ (@) You can refer to the DCMI HAL driver header file for more useful macros
