海思Hi3519AV100sensor移植之一-- imx307

1. 驱动修改， 基于imx291的驱动(imx291_sensor_ctl.c )进行修改， 遵循imx307数据手册修改寄存器即可。（因为imx307与imx291型号差距不大，初始化序列可以参考imx291）

};

2. 按照《sensor调试指南》修改文件，主要集中在sample_comm_vi.c , sample_comm_isp.c

• 下面为驱动程序分析

原文件为sample_comm_isp.c

HI_S32 SAMPLE_COMM_ISP_Sensor_Regiter_callback(ISP_DEV IspDev, HI_U32 u32SnsId)
{
    ALG_LIB_S stAeLib;
    ALG_LIB_S stAwbLib;
    const ISP_SNS_OBJ_S* pstSnsObj;
    HI_S32    s32Ret = -1;

    if (MAX_SENSOR_NUM <= u32SnsId)
    {
        SAMPLE_PRT("invalid sensor id: %d\n", u32SnsId);
        return HI_FAILURE;
    }

    pstSnsObj = SAMPLE_COMM_ISP_GetSnsObj(u32SnsId);

    if (HI_NULL == pstSnsObj)
    {
        SAMPLE_PRT("sensor %d not exist!\n", u32SnsId);
        return HI_FAILURE;
    }

 

跳入SAMPLE_COMM_ISP_GetSnsObj，发现原来是缺少了stSnsImx307Obj;所以我在这里添加了相应的代码

    switch (enSnsType)
    {

        
        case SONY_IMX290_MIPI_2M_30FPS_12BIT:
        case SONY_IMX290_MIPI_2M_30FPS_12BIT_WDR2TO1:
            return &stSnsImx290Obj;
       /*添加的代码*/
        case SONY_IMX307_MIPI_2M_30FPS_12BIT:            
            return &stSnsImx307Obj;
        ...
    }

该结构体定义在

imx290_cmos.c ； 添加stSnsImx307Obj

ISP_SNS_OBJ_S stSnsImx307Obj =
{
    .pfnRegisterCallback    = sensor_register_callback,
    .pfnUnRegisterCallback  = sensor_unregister_callback,
    .pfnStandby             = imx291_standby,
    .pfnRestart             = imx291_restart,
    .pfnMirrorFlip          = HI_NULL,
    .pfnWriteReg            = imx291_write_register,
    .pfnReadReg             = imx291_read_register,
    .pfnSetBusInfo          = imx291_set_bus_info,
    .pfnSetInit             = sensor_set_init
};

定义在.c文件所有肯定是外部引用，extern , 位置

hi_sns_ctrl.h ； 同理添加 extern ISP_SNS_OBJ_S stSnsImx307Obj

extern ISP_SNS_OBJ_S stSnsMn34220Obj;
extern ISP_SNS_OBJ_S stSnsImx377Obj;
extern ISP_SNS_OBJ_S stSnsImx299Obj;
extern ISP_SNS_OBJ_S stSnsImx477Obj;
extern ISP_SNS_OBJ_S stSnsImx299SlvsObj;
extern ISP_SNS_OBJ_S stSnsImx290Obj;
extern ISP_SNS_OBJ_S stSnsImx327Obj;

extern ISP_SNS_OBJ_S stSnsImx335Obj;

/*添加的代码*/
extern ISP_SNS_OBJ_S stSnsImx307Obj;
