veye5_mipi_i2c.sh user guide

1 Overview

This script is an open source program to configure the camera module by direct access to i2c registers.

Applicable models: VEYE-MIPI-IMX335

2 veye5_mipi_i2c.sh help

Usage:  ./veye_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

-b [i2c bus num]  i2c bus number

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

3 i2c bus number on different board

Please refer to the following article to determine which -b parameter you need to use.

i2c bus number on different boards

4 Functions list

The part in square brackets [param] in the following code indicates the variable.

4.1 manufacturer

./veye5_mipi_i2c.sh -r -f manufacturer

Read manufacturer information, always returns:

Manufacturer is VEYE

4.2 model

./veye5_mipi_i2c.sh -r -f model

Read the device model, for example: VEYE_MIPI_IMX335

4.3 version

./veye5_mipi_i2c.sh -r -f version

Reads the version number, for example:
