MV Series MIPI Camera Register Map/zh
MV系列和RAW系列MIPI摄像机模组寄存器列表
1 概述
1.1 寄存器特征
寄存器地址的长度为2字节，值的长度为4字节。
寄存器读写属性分为RW，RO，WO三种。只有RW属性的可以保存到摄像机flash中。
寄存器值包括几种类型：int，bool，enum，ascii。
1.2 i2c通信协议
模组支持通过i2c协议进行参数配置。摄像机默认的i2c从地址是0x3b,这个地址是可以修改的。
i2c读写寄存器时采用大端字节序，即高字节在前的顺序。
为了方便客户使用，我们提供了linux下开源的shell脚本，帮助进行每个寄存器的读写。
下表中script function一列表示此寄存器对应的shell脚本的功能函数。
1.3 Update timing
摄像机有两种状态，standby和running。上电后进入standby状态，开始图像采集后进入running状态。
下表中，Update timing的类型有：
A：任何时刻都可以读写。
S: running状态下可读不可写。
-：任何时刻都只读。
1.4 Raw series Support
RAW系列摄像机的功能是MV系列摄像机的子集。
它包含一个MCU，用于sensor模式的配置和外触发的延迟。
特别的，它支持Sensor Direct Access模式。在此模式下，MCU放弃对sensor的控制和操作，开放sensor的i2c给客户直接控制。MCU只保留极少必要的寄存器功能。
N：不支持。
S：普通模式下支持。
SDA：Sensor Direct Access模式下支持。
