VEYE-MIPI-X 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。

第一次使用需要确认此目录下文件都具备可执行权限。

chmod +x *

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

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

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 of VEYE-MIPI-327 or J2 pin1 of VEYE-MIPI-IMX327S.

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.

5.14 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.

5.15 nodf

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

Number of dropped frames

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

actual framerate = original framerate /(1+nodf)

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

./veye_mipi_i2c.sh -r -f nodf

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

ntof range is [0-0xFF], default 0.

5.16 capture

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

./veye_mipi_i2c.sh -w -f capture

Output the next frame. 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.

5.17 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: 0x1

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

./veye_mipi_i2c.sh -r -f brightness

./veye_mipi_i2c.sh -w -f brightness -p1 0x32

AE的目标亮度,范围[0,0x64]

5.19 aespeed

AE 调节速度p1为agc速度,p2为shutter速度,由慢到快[0,0x64]

5.20 contrast

./veye_mipi_i2c.sh -r -f contrast

./veye_mipi_i2c.sh -w -f contrast -p1 0x32

./veye_mipi_i2c.sh -r -f wdrtargetbr

./veye_mipi_i2c.sh -w -f wdrtargetbr -p1 0x80

宽动态模式下的整体亮度目标值。

WDR模式生效,[0-0xFF]默认值0x80,WDR模式下,值越大,亮度越高。

5.24 wdrbtargetbr

./veye_mipi_i2c.sh -r -f wdrbtargetbr

./veye_mipi_i2c.sh -w -f wdrbtargetbr -p1 0x80

宽动态模式下的亮区亮度目标值。

WDR模式生效,[0-0xFF],默认值为0x30,值越大,亮区越亮。

此参数的效果与实际场景有关,会存在一个[0-X]的无效区,X与实际场景有关。

并不是说调整为0,则亮区会变黑。
