<> 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 34 (#) Program the required configuration through following parameters:

<> 144:ef7eb2e8f9f7 36 and enable capture using HAL_DCMI_Start_DMA() function.
