| mbed_official | 235:685d5f11838f | 20 | The sequence below describes how to use this driver to capture image |
| mbed_official | 235:685d5f11838f | 21 | from a camera module connected to the DCMI Interface. |
| mbed_official | 235:685d5f11838f | 22 | This sequence does not take into account the configuration of the |
| mbed_official | 235:685d5f11838f | 23 | camera module, which should be made before to configure and enable |
| mbed_official | 235:685d5f11838f | 24 | the DCMI to capture images. |
| mbed_official | 235:685d5f11838f | 25 | |
| mbed_official | 235:685d5f11838f | 26 | (#) Program the required configuration through following parameters: |
| mbed_official | 235:685d5f11838f | 27 | horizontal and vertical polarity, pixel clock polarity, Capture Rate, |
| mbed_official | 235:685d5f11838f | 28 | Synchronization Mode, code of the frame delimiter and data width |
| mbed_official | 235:685d5f11838f | 29 | using HAL_DCMI_Init() function. |
| mbed_official | 235:685d5f11838f | 30 | |
| mbed_official | 235:685d5f11838f | 31 | (#) Configure the DMA2_Stream1 channel1 to transfer Data from DCMI DR |
| mbed_official | 235:685d5f11838f | 32 | register to the destination memory buffer. |
| mbed_official | 235:685d5f11838f | 33 | |
| mbed_official | 235:685d5f11838f | 34 | (#) Program the required configuration through following parameters: |
| mbed_official | 235:685d5f11838f | 35 | DCMI mode, destination memory Buffer address and the data length |
| mbed_official | 235:685d5f11838f | 36 | and enable capture using HAL_DCMI_Start_DMA() function. |
| mbed_official | 235:685d5f11838f | 37 | |
| mbed_official | 235:685d5f11838f | 38 | (#) Optionally, configure and Enable the CROP feature to select a rectangular |
| mbed_official | 235:685d5f11838f | 39 | window from the received image using HAL_DCMI_ConfigCrop() |
| mbed_official | 235:685d5f11838f | 40 | and HAL_DCMI_EnableCROP() functions |
| mbed_official | 235:685d5f11838f | 41 | |
| mbed_official | 235:685d5f11838f | 42 | (#) The capture can be stopped using HAL_DCMI_Stop() function. |
| mbed_official | 235:685d5f11838f | 43 | |
| mbed_official | 235:685d5f11838f | 44 | (#) To control DCMI state you can use the function HAL_DCMI_GetState(). |
