bogdanm 0:9b334a45a8ff 17 ##### How to use this driver #####
bogdanm 0:9b334a45a8ff 18 ==============================================================================
bogdanm 0:9b334a45a8ff 19 [..]
bogdanm 0:9b334a45a8ff 20 The sequence below describes how to use this driver to capture image
bogdanm 0:9b334a45a8ff 21 from a camera module connected to the DCMI Interface.
bogdanm 0:9b334a45a8ff 22 This sequence does not take into account the configuration of the
bogdanm 0:9b334a45a8ff 23 camera module, which should be made before to configure and enable
bogdanm 0:9b334a45a8ff 24 the DCMI to capture images.
bogdanm 0:9b334a45a8ff 25
bogdanm 0:9b334a45a8ff 26 (#) Program the required configuration through following parameters:
bogdanm 0:9b334a45a8ff 27 horizontal and vertical polarity, pixel clock polarity, Capture Rate,
bogdanm 0:9b334a45a8ff 28 Synchronization Mode, code of the frame delimiter and data width
bogdanm 0:9b334a45a8ff 29 using HAL_DCMI_Init() function.
bogdanm 0:9b334a45a8ff 30
bogdanm 0:9b334a45a8ff 31 (#) Configure the DMA2_Stream1 channel1 to transfer Data from DCMI DR
bogdanm 0:9b334a45a8ff 32 register to the destination memory buffer.
bogdanm 0:9b334a45a8ff 33
bogdanm 0:9b334a45a8ff 34 (#) Program the required configuration through following parameters:
bogdanm 0:9b334a45a8ff 35 DCMI mode, destination memory Buffer address and the data length
bogdanm 0:9b334a45a8ff 36 and enable capture using HAL_DCMI_Start_DMA() function.
bogdanm 0:9b334a45a8ff 37
bogdanm 0:9b334a45a8ff 38 (#) Optionally, configure and Enable the CROP feature to select a rectangular
bogdanm 0:9b334a45a8ff 39 window from the received image using HAL_DCMI_ConfigCrop()
bogdanm 0:9b334a45a8ff 40 and HAL_DCMI_EnableCROP() functions
bogdanm 0:9b334a45a8ff 41
bogdanm 0:9b334a45a8ff 42 (#) The capture can be stopped using HAL_DCMI_Stop() function.
bogdanm 0:9b334a45a8ff 43
bogdanm 0:9b334a45a8ff 44 (#) To control DCMI state you can use the function HAL_DCMI_GetState().

bogdanm 0:9b334a45a8ff 49 Below the list of most used macros in DCMI HAL driver.
bogdanm 0:9b334a45a8ff 50

bogdanm 0:9b334a45a8ff 53 (+) __HAL_DCMI_GET_FLAG: Get the DCMI pending flags.
bogdanm 0:9b334a45a8ff 54 (+) __HAL_DCMI_CLEAR_FLAG: Clear the DCMI pending flags.
bogdanm 0:9b334a45a8ff 55 (+) __HAL_DCMI_ENABLE_IT: Enable the specified DCMI interrupts.
bogdanm 0:9b334a45a8ff 56 (+) __HAL_DCMI_DISABLE_IT: Disable the specified DCMI interrupts.
bogdanm 0:9b334a45a8ff 57 (+) __HAL_DCMI_GET_IT_SOURCE: Check whether the specified DCMI interrupt has occurred or not.
bogdanm 0:9b334a45a8ff 58
