- * @brief DCMI HAL module driver\r
- * This file provides firmware functions to manage the following \r
- * functionalities of the Digital Camera Interface (DCMI) peripheral:\r
- * + Initialization and de-initialization functions\r
- * + IO operation functions\r
- * + Peripheral Control functions \r
- * + Peripheral State and Error functions \r

- ##### How to use this driver #####\r
- ==============================================================================\r
- [..]\r
- The sequence below describes how to use this driver to capture image\r
- from a camera module connected to the DCMI Interface.\r
- This sequence does not take into account the configuration of the\r
- camera module, which should be made before to configure and enable\r
- the DCMI to capture images.\r
-\r
- (#) Program the required configuration through following parameters:\r
- horizontal and vertical polarity, pixel clock polarity, Capture Rate,\r
- Synchronization Mode, code of the frame delimiter and data width \r
- using HAL_DCMI_Init() function.\r
-\r
- (#) Configure the DMA2_Stream1 channel1 to transfer Data from DCMI DR\r
- register to the destination memory buffer.\r
-\r
- (#) Program the required configuration through following parameters:\r
- DCMI mode, destination memory Buffer address and the data length \r
- and enable capture using HAL_DCMI_Start_DMA() function.\r
-\r
- (#) Optionally, configure and Enable the CROP feature to select a rectangular\r
- window from the received image using HAL_DCMI_ConfigCrop() \r
- and HAL_DCMI_EnableCROP() functions\r
-\r
- (#) The capture can be stopped using HAL_DCMI_Stop() function.\r
-\r
- (#) To control DCMI state you can use the function HAL_DCMI_GetState().\r
-\r
- *** DCMI HAL driver macros list ***\r
- ============================================= \r
- [..]\r
- Below the list of most used macros in DCMI HAL driver.\r
- \r
- (+) __HAL_DCMI_ENABLE: Enable the DCMI peripheral.\r
- (+) __HAL_DCMI_DISABLE: Disable the DCMI peripheral.\r
- (+) __HAL_DCMI_GET_FLAG: Get the DCMI pending flags.\r
- (+) __HAL_DCMI_CLEAR_FLAG: Clear the DCMI pending flags.\r
- (+) __HAL_DCMI_ENABLE_IT: Enable the specified DCMI interrupts.\r
- (+) __HAL_DCMI_DISABLE_IT: Disable the specified DCMI interrupts.\r
- (+) __HAL_DCMI_GET_IT_SOURCE: Check whether the specified DCMI interrupt has occurred or not.\r
- \r
- [..] \r
- (@) You can refer to the DCMI HAL driver header file for more useful macros\r
