cs_mipi_i2c.sh 参数配置脚本使用说明

1 介绍

cs_mipi_i2c.sh 脚本为通过I2C协议对CS-MIPI-X系列的摄像头进行配置的工具集。

目录下总共4个文件，camera_i2c_config、i2c_read、i2c_write、cs_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

./enable_i2c_vc.sh

./camera_i2c_config

配置管脚，然后执行cs_mipi_i2c.sh

2.1 camera_i2c_config 使用说明

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 cs_mipi_i2c.sh 使用说明

./cs_mipi_i2c.sh

this shell scripts should be used for CS-MIPI-IMX307!

Usage:  ./cs_mipi_i2c.sh [-r/w] [-f] function name -p1 param1 -p2 param2 -p3 param3 -b bus

options:

    -r                       read

    -w                       write

    -f [function name]       function name

    -p1 [param1]                           param1 of each function

    -p2 [param1]                           param2 of each function

    -p3 [param1]                           param3 of each function

    -b [i2c bus num]               i2c bus number

    -d [i2c addr]                  i2c addr if not default 0x3b

support functions: devid,hdver,camcap,firmwarever,productmodel,videofmtcap,videofmt,ispcap,i2caddr,streammode,powerhz,sysreset,paramsave

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。
