#if (CONFIG_SENSOR_IIC_ADDR_1 != 0x00)

#endif
#if (PMEM_CAM_SIZE > 0)

这里面包括图片尺寸大小，分辨率等设置。
4.具体摄像头的寄存器配置：
首先：make menuconfig
Device Drivers------>
Multimedia support ----->
Video capture adapters ----->
选择相应的Camera驱动，比如GC0309
然后根据具体的需求到gc0309.c里面去按照手册配置寄存器。
主要是修改1.1里面前置和后置摄像头的引脚，地址，名字，以及一些参数。
及2和3里面初始化的配置
