lypinator | 0:bb348c97df44 | 15 | ##### How to use this driver ##### |
lypinator | 0:bb348c97df44 | 16 | ============================================================================== |
lypinator | 0:bb348c97df44 | 17 | [..] |
lypinator | 0:bb348c97df44 | 18 | The sequence below describes how to use this driver to capture image |
lypinator | 0:bb348c97df44 | 19 | from a camera module connected to the DCMI Interface. |
lypinator | 0:bb348c97df44 | 20 | This sequence does not take into account the configuration of the |
lypinator | 0:bb348c97df44 | 21 | camera module, which should be made before to configure and enable |
lypinator | 0:bb348c97df44 | 22 | the DCMI to capture images. |
lypinator | 0:bb348c97df44 | 23 | |
lypinator | 0:bb348c97df44 | 24 | (#) Program the required configuration through following parameters: |
lypinator | 0:bb348c97df44 | 25 | horizontal and vertical polarity, pixel clock polarity, Capture Rate, |
lypinator | 0:bb348c97df44 | 26 | Synchronization Mode, code of the frame delimiter and data width |
lypinator | 0:bb348c97df44 | 27 | using HAL_DCMI_Init() function. |
lypinator | 0:bb348c97df44 | 28 | |
lypinator | 0:bb348c97df44 | 29 | (#) Configure the DMA2_Stream1 channel1 to transfer Data from DCMI DR |
lypinator | 0:bb348c97df44 | 30 | register to the destination memory buffer. |
lypinator | 0:bb348c97df44 | 31 | |
lypinator | 0:bb348c97df44 | 32 | (#) Program the required configuration through following parameters: |
lypinator | 0:bb348c97df44 | 33 | DCMI mode, destination memory Buffer address and the data length |
lypinator | 0:bb348c97df44 | 34 | and enable capture using HAL_DCMI_Start_DMA() function. |
lypinator | 0:bb348c97df44 | 35 | |
lypinator | 0:bb348c97df44 | 36 | (#) Optionally, configure and Enable the CROP feature to select a rectangular |
lypinator | 0:bb348c97df44 | 37 | window from the received image using HAL_DCMI_ConfigCrop() |
lypinator | 0:bb348c97df44 | 38 | and HAL_DCMI_EnableCROP() functions |
lypinator | 0:bb348c97df44 | 39 | |
lypinator | 0:bb348c97df44 | 40 | (#) The capture can be stopped using HAL_DCMI_Stop() function. |
lypinator | 0:bb348c97df44 | 41 | |
lypinator | 0:bb348c97df44 | 42 | (#) To control DCMI state you can use the function HAL_DCMI_GetState(). |
