Without definitions for BSP_CAMERA_IRQHandler and BSP_CAMERA_DMA_IRQHandler methods, DCMI IRQs were not being serviced by HAL_DCMI_IRQHandler. This broke the IRQ-based DCMI API.

| bcostm | 6:e1d9da7fe856 | 7 | * @brief This file includes the driver for Camera modules mounted on |
| bcostm | 6:e1d9da7fe856 | 8 | * STM32746G-Discovery board. |
| bcostm | 6:e1d9da7fe856 | 9 | @verbatim |
| bcostm | 6:e1d9da7fe856 | 10 | How to use this driver: |
| bcostm | 6:e1d9da7fe856 | 11 | ------------------------ |
| bcostm | 6:e1d9da7fe856 | 12 | - This driver is used to drive the camera. |
| bcostm | 6:e1d9da7fe856 | 13 | - The OV9655 component driver MUST be included with this driver. |
| bcostm | 6:e1d9da7fe856 | 14 | |
| bcostm | 6:e1d9da7fe856 | 15 | Driver description: |
| bcostm | 6:e1d9da7fe856 | 16 | ------------------- |
| bcostm | 6:e1d9da7fe856 | 17 | + Initialization steps: |
| bcostm | 6:e1d9da7fe856 | 18 | o Initialize the camera using the BSP_CAMERA_Init() function. |
| bcostm | 6:e1d9da7fe856 | 19 | o Start the camera capture/snapshot using the CAMERA_Start() function. |
| bcostm | 6:e1d9da7fe856 | 20 | o Suspend, resume or stop the camera capture using the following functions: |
| bcostm | 6:e1d9da7fe856 | 21 | - BSP_CAMERA_Suspend() |
| bcostm | 6:e1d9da7fe856 | 22 | - BSP_CAMERA_Resume() |
| bcostm | 6:e1d9da7fe856 | 23 | - BSP_CAMERA_Stop() |
| bcostm | 6:e1d9da7fe856 | 24 | |
| bcostm | 6:e1d9da7fe856 | 25 | + Options |
| bcostm | 6:e1d9da7fe856 | 26 | o Increase or decrease on the fly the brightness and/or contrast |
| bcostm | 6:e1d9da7fe856 | 27 | using the following function: |
| bcostm | 6:e1d9da7fe856 | 28 | - BSP_CAMERA_ContrastBrightnessConfig |
| bcostm | 6:e1d9da7fe856 | 29 | o Add a special effect on the fly using the following functions: |
| bcostm | 6:e1d9da7fe856 | 30 | - BSP_CAMERA_BlackWhiteConfig() |
| bcostm | 6:e1d9da7fe856 | 31 | - BSP_CAMERA_ColorEffectConfig() |
