MV Series MIPI Camera Register Map

1 Overview

1.1 Register Features

The register address length is 4 bytes and the data length is 2 bytes.

Register R/W attributes: RW, RO, WO. Only the RW type can be saved to the camera flash.

Register values have several types: uint（unsigned int）, bool, enum, ascii.

1.2 I2c communication protocol

The module supports parameter configuration via i2c protocol. The default i2c slave address of the camera is 0x3b which can be modified.
I2c data input order is MSB-first transfer.

We provide open source shell scripts under Linux to help read and write each register.

The script function column in the following table indicates the function name in the shell script corresponding to this register.

1.3 Update timing

The camera has two states, standby and running, after the start of image acquisition into the running state.

In the following table, Update timing is divided into "A" and "S".

A: Read and write at any time.

S: Read only at Running state.
