MV系列MIPI摄像机模组寄存器列表

1 概述

1.1 寄存器特征

寄存器地址长度为4字节，数据长度为2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，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。

-：任何时刻都可读。

However, due to the properties of the sensor, the actual exposure time unit of the sensor is 1 line, can not be accurate to 1us. Note2：For all gain-related parameters, the register value is 10 times the number of dB. For example, if the register is 101, it means 10.1dB. The range and step vary according to the model. Note3: AE: Auto exposure; AG: Auto Gain; AA: AE and AG. Note4: The AAROI coordinates are relative coordinates within the roi range. 6 IO控制 Address Name Description Data Type R/W Update timing script function 0x1000 Trigger Delay Trigger delay. range: 0 to 1000000 (unit: microsecond) uint RW S trgdelay 0x1004 Trigger Activation 0: Rising edge 1: Falling edge uint RW S trgedge 0x1008 Trigger Filter Enable 0: No filtering 1: Rising edge filtering (filtering out low-level interference signals) 2: Falling edge filtering (filtering out high level interference signals) 3 :Both rising edge and falling edge filtering uint RW S trgfilter_enable 0x100c Trigger Filter Width Trigger signal filtering window width range: 1 to 1000000 (unit: microsecond) uint RW S trgfilter_time 0x1010 Exposure Delay Exposure delay, i.e. the time to turn on the Strobe signal in advance. range: 1 to 1000000 (unit: microsecond) uint RW S trgexp_delay 0x1014 TriggerIN IO status trigger in IO pin status. enum RO - gpios_status 0x1020 GPIO1_OutSelect 0: Strobe 1: UserOut uint RW A outio1_mode 0x1024 GPIO1 UserOut User-defined output signal. enum RW A outio1_usr 0x1028 GPIO1 Reverse Output signal reversal. bool RW A outio1_rvs 0x102C GPIO1 OutStatus GPIO1 IO pin status. enum RO - gpios_status 0x1030 GPIO2_OutSelect 0: Strobe 1: UserOut 2: TriggerWait; trigger wait status.
