sahilmgandhi 18:6a4db94011d3 17 ##### How to use this driver #####
sahilmgandhi 18:6a4db94011d3 18 ==============================================================================
sahilmgandhi 18:6a4db94011d3 19 [..]
sahilmgandhi 18:6a4db94011d3 20 The sequence below describes how to use this driver to capture image
sahilmgandhi 18:6a4db94011d3 21 from a camera module connected to the DCMI Interface.
sahilmgandhi 18:6a4db94011d3 22 This sequence does not take into account the configuration of the
sahilmgandhi 18:6a4db94011d3 23 camera module, which should be made before to configure and enable
sahilmgandhi 18:6a4db94011d3 24 the DCMI to capture images.
sahilmgandhi 18:6a4db94011d3 25
sahilmgandhi 18:6a4db94011d3 26 (#) Program the required configuration through following parameters:
sahilmgandhi 18:6a4db94011d3 27 horizontal and vertical polarity, pixel clock polarity, Capture Rate,
sahilmgandhi 18:6a4db94011d3 28 Synchronization Mode, code of the frame delimiter and data width
sahilmgandhi 18:6a4db94011d3 29 using HAL_DCMI_Init() function.
sahilmgandhi 18:6a4db94011d3 30
sahilmgandhi 18:6a4db94011d3 31 (#) Configure the DMA2_Stream1 channel1 to transfer Data from DCMI DR
sahilmgandhi 18:6a4db94011d3 32 register to the destination memory buffer.
sahilmgandhi 18:6a4db94011d3 33
sahilmgandhi 18:6a4db94011d3 34 (#) Program the required configuration through following parameters:
sahilmgandhi 18:6a4db94011d3 35 DCMI mode, destination memory Buffer address and the data length
sahilmgandhi 18:6a4db94011d3 36 and enable capture using HAL_DCMI_Start_DMA() function.
sahilmgandhi 18:6a4db94011d3 37
sahilmgandhi 18:6a4db94011d3 38 (#) Optionally, configure and Enable the CROP feature to select a rectangular
sahilmgandhi 18:6a4db94011d3 39 window from the received image using HAL_DCMI_ConfigCrop()
sahilmgandhi 18:6a4db94011d3 40 and HAL_DCMI_EnableCROP() functions
sahilmgandhi 18:6a4db94011d3 41
sahilmgandhi 18:6a4db94011d3 42 (#) The capture can be stopped using HAL_DCMI_Stop() function.
sahilmgandhi 18:6a4db94011d3 43
sahilmgandhi 18:6a4db94011d3 44 (#) To control DCMI state you can use the function HAL_DCMI_GetState().
