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 possible value is:

A: Read and write at any time.

S: Read only at Running state.

-: Read only at any time.

2 Basic Parameters

Address Name Description Data Type R/W Update timing script function
0x0000 Manufacturer Name String containing the self-describing name of the manufacturer. “VEYE” ascii RO - manufacturer
0x0004 Model Name Product Model Code.

0x178 : MV-MIPI-IMX178

enum RO - model
0x0008 Sensor Name Sensor Model:

0x178 : IMX178LLJ

enum RO -
0x000C Serial Number Unique product serial number uint RO -
0x0010 Device Version Firmware version number. The high 16 bits are the Control version and the low 16 bits are the Logic version.

For example, 0x01020304 means Control version is 1.2 and Logic version is 3.4.

uint RO - version
0x0014 Factory Param All parameters restored to factory default values. bool WO A factoryparam
0x0018 Param save to flash Save the parameters to flash, and they will not be lost when power off. bool WO A paramsave
0x001C System reboot Reboot the camera. bool WO A reboot
0x0020 Time stamp Time after system startup in Milliseconds. uint RO - timestamp
0x0024 Error Code System error code, each bit represents an error type.

bit0: sensor error.

bit1: Logic module startup error.

bit2: Logic module communication error.

bit5: AA(AE&AG) regulation cannot reach the target.

bit6: Authorization failure.

uint RO - errcode

3 Image Acquisition

Address Name Description Data Type R/W Update timing script function
0x0400 Image Acquisition Start/Stop acquisition

There is no image output after the camera is powered on, which means it is in the standby state.

After writing 1 to this register, it enters the running state and starts outputting images or waiting for the trigger signal.

bool WO A imgacq
0x0404 Trigger Mode 0:Video streaming mode

1:Normal trigger mode.

2:High-speed continuous trigger mode.

See product manual for details.

enum RW S trgmode
0x0408 Trigger Source 0: Software trigger mode.

1: Hardware trigger mode.

enum RW S trgsrc
0x040C Trigger Number The number of image frames output by one trigger signal in trigger mode. Range:[1.255] uint RW S trgnum
0x0410 Trigger Interval Trigger interval in normal trigger mode, in microseconds. Range:[0.0xFFFFFF] uint RW S trginterval
0x0414 Trigger Software Software trigger command, write 1 for one trigger. bool WO A trgone
0x0418 Trigger Count Trigger count statistics.

The high 16 bits indicate the number of trigger loss, and the low 16 bits indicate the total number of triggers.

Write 1 to clear the count.

uint RW A trgcount
0x041C I2C ADDR I2c address. Range[0x03,0x77]. uint RW A i2caddr
