使用cy7c68013调试mt9v011 ov7670 摄像头测试 icamera视频采集调试
采集底板选用cp601d，原理图参考icamera设计，使用cy7c68013a芯片设计，固件刷icamera-106.iic（106后的版本均兼容）
注意好管脚顺序
OE接地使能，
复位管脚接高电平，处于正常工作
编写配置文件
iic配置地址为0xba
0x1a, 0x00, 0xBA, // 42 0x5A // sensor slave id
0x1a, 0x01, 0x00, // pwdn low
0x1a, 0x02, 0x01, // wordwide <1:8 bit, else:16 bit>
0x1a, 0x03, 0x01, // register address length 2byte
0x1a, 0x04, 0x02, // register value length 1byte
//0x1a, 0x05, 0x01, // reset pin(PC2)
0x1a, 0x06, 0x01, // IFCLK polarity
0x1a, 0x0D, 0x02, // IFCLK 24

参考芯片手册调整好配置文件，即可出图
视频显示
调整rgb各个通道增益和曝光，可以让图像更柔和，亮度更合适。
这就是所谓的白平衡和曝光调节，可以实时看效果

线序定义
安装效果如下，两类摄像头设计的时候线序有所不同，所以装不同位置区分

拍照效果
启用ov7670的内部自动增益，自动曝光，自动白平衡，采集效果显著比人为手工初步简单配置的效果会好，
