VEYE-MIPI-290/327 I2C.sh用户手册

1 介绍

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

2 树莓派配置管脚，非树莓派忽略此步

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

2.1 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,cameramode, notf, capture, csienable

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

3.1.11 cameramode

Requirements：hdver >= 0x3

./veye_mipi_i2c.sh -r -f cameramode

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

value description
0x0 Stream mode
0x1 Capture mode

Stream mode: stream output

Caputre mode: output the next frame each capture cmd.

3.1.12 notf

Requirements：hdver >= 0x3, effective in Stream mode

Number of dropped frames

It is a method of framerate control, output one frame,discard notf frames,output next frame, and so on.

actual framerate = original framerate /（1+notf）

For example，if the original framerate is 30fps, set notf to 2, then actual framerate is 10fps.

./veye_mipi_i2c.sh -r -f notf

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

ntof range is [0-0xFF]， default 0.

3.1.13 capture

Requirements：hdver >= 0x3, effective in Capture mode

./veye_mipi_i2c.sh -w -f capture

Output the next frame each cmd。This cmd does not interfere the sensor， it just output the next frame (the newest frame).

So it is not trigger mode, there will be a delay[0,1/framerate] between the cmd and the frame exposure.

It is applicable to those that do not require a high level of real-time performance.

3.1.14 csienable

Requirements：hdver >= 0x3

./veye_mipi_i2c.sh -r -f csienable

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

value description
0x0 suspend csi output
0x1 enable csi output

default: 0x0

Note: This is not low power mode, the camera is still working.
