7.1 相关代码位置：

mediatek\config\XXXX（红色字为具体的项目名）

文件：ProjectConfig.mk

CUSTOM_KERNEL_IMGSENSOR = …… gc2235_raw

CUSTOM_KERNEL_MAIN_IMGSENSOR = …… gc2235_raw

CUSTOM_HAL_IMGSENSOR = …… gc2235_raw

CUSTOM_HAL_MAIN_IMGSENSOR = …… gc2235_raw

kernel:

\mediatek\custom\common\kernel\imgsensor\gc2235_raw

mediatek\custom\common\kernel\imgsensor\src

文件：kd_sensorlist.h

添加内容：

UINT32 GC2235SensorInit(PSENSOR_FUNCTION_STRUCT *pfFunc);

ACDK_KD_SENSOR_INIT_FUNCTION_STRUCT

kdSensorList[MAX_NUM_OF_SUPPORT_SENSOR+1] =

{

#if defined(GC2235_RAW)

    {GC2235_SENSOR_ID, SENSOR_DRVNAME_GC2235_RAW, GC2235SensorInit}, 

#endif

};

mediatek\custom\common\kernel\imgsensor\inc

文件：kd_imgsensor.h

添加内容：

#define GC2235_SENSOR_ID                 0x2235

#define SENSOR_DRVNAME_GC2235_RAW    "gc2235"

hal

\mediatek\custom\common\hal\imgsensor\gc2235_raw

mediatek\custom\common\hal\imgsensor\src

文件：sensorlist.cpp

添加内容：

MSDK_SENSOR_INIT_FUNCTION_STRUCT SensorList[] =

{

…………

#if defined(GC2235_RAW)

RAW_INFO(GC2235_SENSOR_ID, SENSOR_DRVNAME_GC2235_RAW, NULL), 

#endif

…………

};

注意：在 kd_SensorList.h 和 SensorList.cpp 里面添加驱动的时候要注意，Sensor 添加的位置要一样。否则驱动会跑乱，轻则 ISP 参数不对，重则 Sensor 无法启动。

7.2 拍照图片尺寸设置：

..\mediatek\custom\\hal\camera\camera\cfg_ftbl_$prj$_raw_main.h

//Capture Size

CONFIG_FEATURE(FID_CAP_SIZE, 

    BY_DEFAULT(CAPTURE_SIZE_1600_1200), 

    /*BY_DEFAULT(CAPTURE_SIZE_2560_1920),  modify*/

    CAPTURE_SIZE_640_480,

    CAPTURE_SIZE_1280_960, CAPTURE_SIZE_1600_1200,

)

7.3 Camera物理角度旋转

90度：

\alps\mediatek\custom\$prj$\hal\imgsensor\src\cfg_setting_imgsensor.cpp

    static SensorOrientation_T const inst = {

        u4Degree_0  : 180,//90,   //  main sensor in degree (0, 90, 180, 270)

        u4Degree_1  : 0,//90,    //  sub  sensor in degree (0, 90, 180, 270)

180度：

Sensor FAE提供修改方法。

7.4 Camera 相同sensor id兼容方式（前后sensor id 一致）：

//配置区分：

CUSTOM_KERNEL_IMGSENSOR = gc0308_yuv # gc0308_sub_yuv

CUSTOM_KERNEL_MAIN_IMGSENSOR = gc0308_yuv # gc0308_sub_yuv

CUSTOM_HAL_IMGSENSOR = gc0308_yuv # gc0308_sub_yuv

CUSTOM_HAL_MAIN_IMGSENSOR = gc0308_yuv # gc0308_sub_yuv

//kernel:函数名也要区分

\alps\mediatek\custom\common\kernel\imgsensor\gc0308_sub_yuv

\alps\mediatek\custom\common\kernel\imgsensor\gc0308_yuv

//hal: 函数名也要区分

\alps\mediatek\custom\common\hal\imgsensor\gc0308_sub_yuv

\alps\mediatek\custom\common\hal\imgsensor\gc0308_yuv

//kdSensorList 和 SensorList 里面添加驱动也要区分，sensor id不要区分，写成一致，根据前后摄像头开关代码区分。
