veye_mipi_i2c.sh详细说明

1 介绍

目录下总共4个文件，camera_i2c_config、i2c_read、i2c_write、veye_mipi_i2c.sh。

你需要先运行camera_i2c_config

./enable_i2c_vc.sh

./camera_i2c_config

配置管脚，然后执行veye_mipi_i2c.sh

2 camera_i2c_config USAGE

连接树莓派Computer Module情况下，运行

./camera_i2c_config [cameranum]

cameranum description
0 CAM0
1 CAM1

连接树莓派经典版型情况下，直接运行

./camera_i2c_config

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

对于树莓派Pi3B / Pi3B+ / 3A / 4B(1G/2G/4G)，使用i2c0, 对于Compute Module/ CM3，使用i2c1,请添加-b1 选项。

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 Block 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.

3.1.10 mshutter

close AE, use manual shutter

./veye_mipi_i2c.sh -r -f mshutter

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