Jerome Coutant 0:146cf26a9bbb 22 User NOTES
Jerome Coutant 0:146cf26a9bbb 23 1. How to use this driver:
Jerome Coutant 0:146cf26a9bbb 24 --------------------------
Jerome Coutant 0:146cf26a9bbb 25 - This driver is used to drive the camera.
Jerome Coutant 0:146cf26a9bbb 26 - The OV9655 component driver MUST be included with this driver.
Jerome Coutant 0:146cf26a9bbb 27
Jerome Coutant 0:146cf26a9bbb 28 2. Driver description:
Jerome Coutant 0:146cf26a9bbb 29 ---------------------
Jerome Coutant 0:146cf26a9bbb 30 + Initialization steps:
Jerome Coutant 0:146cf26a9bbb 31 o Initialize the camera using the BSP_CAMERA_Init() function.
Jerome Coutant 0:146cf26a9bbb 32 o Start the camera capture/snapshot using the CAMERA_Start() function.
Jerome Coutant 0:146cf26a9bbb 33 o Suspend, resume or stop the camera capture using the following functions:
Jerome Coutant 0:146cf26a9bbb 34 - BSP_CAMERA_Suspend()
Jerome Coutant 0:146cf26a9bbb 35 - BSP_CAMERA_Resume()
Jerome Coutant 0:146cf26a9bbb 36 - BSP_CAMERA_Stop()
Jerome Coutant 0:146cf26a9bbb 37
Jerome Coutant 0:146cf26a9bbb 38 + Options
Jerome Coutant 0:146cf26a9bbb 39 o Increase or decrease on the fly the brightness and/or contrast
Jerome Coutant 0:146cf26a9bbb 40 using the following function:
Jerome Coutant 0:146cf26a9bbb 41 - BSP_CAMERA_ContrastBrightnessConfig
Jerome Coutant 0:146cf26a9bbb 42 o Add a special effect on the fly using the following functions:
Jerome Coutant 0:146cf26a9bbb 43 - BSP_CAMERA_BlackWhiteConfig()
Jerome Coutant 0:146cf26a9bbb 44 - BSP_CAMERA_ColorEffectConfig()
