veye_mipi_i2c.sh MANUAL

1 Overview

There are 4 files: camera_i2c_config、i2c_read、i2c_write、veye_mipi_i2c.sh。

Running

./enable_i2c_vc.sh

./camera_i2c_config

first，it will config IO pin.

Then you can run veye_mipi_i2c.sh.

2 camera_i2c_config USAGE

for standard RPI, just run

./camera_i2c_config

for RPI Computer Module

./camera_i2c_config [cameranum]

3 veye_mipi_i2c.sh USAGE

./veye_mipi_i2c.sh

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

support functions: devid,hdver,wdrmode,videoformat,mirrormode,denoise,agc,lowlight,daynightmode,ircutdir,irtrigger,mshutter

Pi3B / Pi3B+ / 3A / 4B(1G/2G/4G)，we use i2c0

Compute Module/ CM3，we use i2c1,please add -b 1 option.

IR-CUT (Infrared cut-off filter) is a mechanical shutter design. It is placed between the lens and the image sensor, and is controlled by a motor or an electromagnet.

IR-CUT has two status: Block or Deliver the infrared.

Color Mode

Image is Color Mode and IR_CUT status Bolck infrared.

Black&White Mode

Image is Black&White Mode and IR_CUT status Deliver infrared.

Trigger Mode

Trigger pin : J3 pin1.

Trigger pin High(3.3~12V),Image is Black&White Mode and IR-CUT status Deliver infrared.

Trigger pin Low(GND),Image is Color Mode and IR-CUT status Bolck infrared.

3.10 mshutter

close AE, use manual shutter

./veye_mipi_i2c.sh -r -f mshutter

./veye_mipi_i2c.sh -w -f mshutter -p1 [value]

value is exposure time（seconds）

If value is greater than or equal to 0x4B, it enters slow shutter mode.
