Mv mipi i2c.sh user guide

mv_mipi_i2c.sh Shell scripts usage

1 Overview

The mv_mipi_i2c.sh script is a tool set for configuring MV MIPI series cameras through the I2C.

This script is essentially an access to registers. For registers, please refer to MV Series MIPI Camera Register Map.

2 Raspberry Pi Only, Set IO config

Running

./enable_i2c_vc.sh

./camera_i2c_config

first，it will config IO pin. Then you can run mv_mipi_i2c.sh.

3 mv_mipi_i2c.sh USAGE

./mv_mipi_i2c.sh

Usage:  ./mv_mipi_i2c.sh [-r/w] [-f] function name -p1 param1 -p2 param2 -b bus

options:

    -r                       read

    -w                       write

    -f [function name]       function name

    -p1 [param1]                           param1 of each function

    -p2 [param1]                           param2 of each function

    -p3 [param3]                           param3 of each function

    -p4 [param4]                           param4 of each function

    -b [i2c bus num]               i2c bus number

    -d [i2c addr]                  i2c addr if not default 0x3b

5 Functions list

5.1 Notes

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

There are some registers that are write-protected in the running state, which will be marked with an asterisk. For example: trgsrc* .

There are some parameters that have strict range restrictions, and it's a good idea to try reading them when you're in doubt.

5.2 Basic Parameters

5.2.1 manufacturer

./mv_mipi_i2c.sh -r -f manufacturer

Get the manufacturer name, which is VEYE.

5.2.2 model

./mv_mipi_i2c.sh -r -f model

Get the product model, such as MV-MIPI-IMX178.

5.2.3 version

./mv_mipi_i2c.sh -r -f version

Get the Controller version number and Logical version number.

The system has two main control chips that serve the control and logic functions respectively.

5.2.4 timestamp

./mv_mipi_i2c.sh -r -f timestamp

Time after system startup in Milliseconds.

This value starts counting again if you call the reboot command, or if the camera reboots unexpectedly.

5.2.5 errcode

./mv_mipi_i2c.sh -r -f errcode

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 brightness.

bit6: Authorization failure.

5.2.6 factoryparam

./mv_mipi_i2c.sh -w -f factoryparam

All parameters restored to factory default values.

5.2.7 paramsave

./mv_mipi_i2c.sh -w -f paramsave

Save all parameters to flash, and they will not be lost when power off.

5.2.8 reboot

./mv_mipi_i2c.sh -w -f reboot

Reboot the camera.

5.2.9 i2caddr

./mv_mipi_i2c.sh -w -f i2caddr -p1 [new]

./mv_mipi_i2c.sh -r -f i2caddr
This module support i2c address changed by software, i2c address range[0x3,0x77].

Only after paramsave and reboot will it really take effect.
