<> 144:ef7eb2e8f9f7 19 [..]
<> 144:ef7eb2e8f9f7 20 The sequence below describes how to use this driver to capture image
<> 144:ef7eb2e8f9f7 21 from a camera module connected to the DCMI Interface.
<> 144:ef7eb2e8f9f7 22 This sequence does not take into account the configuration of the
<> 144:ef7eb2e8f9f7 23 camera module, which should be made before to configure and enable
<> 144:ef7eb2e8f9f7 24 the DCMI to capture images.
<> 144:ef7eb2e8f9f7 25
<> 144:ef7eb2e8f9f7 26 (#) Program the required configuration through following parameters:
<> 144:ef7eb2e8f9f7 27 horizontal and vertical polarity, pixel clock polarity, Capture Rate,
<> 144:ef7eb2e8f9f7 28 Synchronization Mode, code of the frame delimiter and data width
<> 144:ef7eb2e8f9f7 29 using HAL_DCMI_Init() function.
<> 144:ef7eb2e8f9f7 30
<> 144:ef7eb2e8f9f7 31 (#) Configure the DMA2_Stream1 channel1 to transfer Data from DCMI DR
<> 144:ef7eb2e8f9f7 32 register to the destination memory buffer.
<> 144:ef7eb2e8f9f7 33
<> 144:ef7eb2e8f9f7 34 (#) Program the required configuration through following parameters:
<> 144:ef7eb2e8f9f7 35 DCMI mode, destination memory Buffer address and the data length
<> 144:ef7eb2e8f9f7 36 and enable capture using HAL_DCMI_Start_DMA() function.
<> 144:ef7eb2e8f9f7 37
<> 144:ef7eb2e8f9f7 38 (#) Optionally, configure and Enable the CROP feature to select a rectangular
<> 144:ef7eb2e8f9f7 39 window from the received image using HAL_DCMI_ConfigCrop()
<> 144:ef7eb2e8f9f7 40 and HAL_DCMI_EnableCROP() functions
<> 144:ef7eb2e8f9f7 41
<> 144:ef7eb2e8f9f7 42 (#) The capture can be stopped using HAL_DCMI_Stop() function.
<> 144:ef7eb2e8f9f7 43
<> 144:ef7eb2e8f9f7 44 (#) To control DCMI state you can use the function HAL_DCMI_GetState().
