1 veye_mipi_i2c.sh详细说明

1.1 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配置管脚，然后执行veye_mipi_i2c.sh。

1.2 camera_i2c_config USAGE

本脚本实现I2C总线管脚复用的配置。

1.2.1 对于Computer Module

硬件连接：

使用我们提供的树莓派增强款套装，连接camera模组到CMIO底板。

当使用CAM1时：

Attach CD1_SDA (J6 pin 37) to GPIO2 (J5 pin 5).

Attach CD1_SCL (J6 pin 39) to GPIO3 (J5 pin 7).

当使用CAM0时：

Attach CD0_SDA (J6 pin 45) to GPIO44 .

Attach CD0_SCL (J6 pin 47) to GPIO45 .

软件配置

Download dt-blob.bin from [here]，(https://www.raspberrypi.org/documentation/hardware/computemodule/dt-blob-dualcam.bin “here”) rename it to dt-blob.bin and place it in /boot/，then

./camera_i2c_config [cameranum]

1.2.2 其他

./camera_i2c_config

1.3 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

function list and param,ref to [veye_mipi_290_isp_function_and_param.pdf]

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