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]

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
