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]

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
