mbed_official 87:085cde657901 17 ##### How to use this driver #####
mbed_official 87:085cde657901 18 ==============================================================================
mbed_official 87:085cde657901 19 [..]
mbed_official 87:085cde657901 20 The sequence below describes how to use this driver to capture image
mbed_official 87:085cde657901 21 from a camera module connected to the DCMI Interface.
mbed_official 87:085cde657901 22 This sequence does not take into account the configuration of the
mbed_official 87:085cde657901 23 camera module, which should be made before to configure and enable
mbed_official 87:085cde657901 24 the DCMI to capture images.
mbed_official 87:085cde657901 25
mbed_official 87:085cde657901 26 (#) Program the required configuration through following parameters:
mbed_official 87:085cde657901 27 horizontal and vertical polarity, pixel clock polarity, Capture Rate,
mbed_official 87:085cde657901 28 Synchronization Mode, code of the frame delimiter and data width
mbed_official 87:085cde657901 29 using HAL_DCMI_Init() function.
mbed_official 87:085cde657901 30
mbed_official 87:085cde657901 31 (#) Configure the DMA2_Stream1 channel1 to transfer Data from DCMI DR
mbed_official 87:085cde657901 32 register to the destination memory buffer.
mbed_official 87:085cde657901 33
mbed_official 87:085cde657901 34 (#) Program the required configuration through following parameters:
mbed_official 87:085cde657901 35 DCMI mode, destination memory Buffer address and the data length
mbed_official 87:085cde657901 36 and enable capture using HAL_DCMI_Start_DMA() function.
mbed_official 87:085cde657901 37
mbed_official 87:085cde657901 38 (#) Optionally, configure and Enable the CROP feature to select a rectangular
mbed_official 87:085cde657901 39 window from the received image using HAL_DCMI_ConfigCrop()
mbed_official 87:085cde657901 40 and HAL_DCMI_EnableCROP() functions
mbed_official 87:085cde657901 41
mbed_official 87:085cde657901 42 (#) The capture can be stopped using the following HAL_DCMI_Stop() function.
mbed_official 87:085cde657901 43
mbed_official 87:085cde657901 44 (#) To control DCMI state you can use the following function : HAL_DCMI_GetState()
mbed_official 87:085cde657901 45
