1 介绍
本脚本为开源程序，通过是对i2c寄存器的直接访问达到配置摄像头模组的目的。
适用型号：VEYE-MIPI-IMX335
2 veye5_mipi_i2c.sh使用说明
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
-d [i2c addr] i2c addr if not default 0x3b
2.1 i2c bus的说明
2.2 使用详解
2.2.1 manufacturer
./veye5_mipi_i2c.sh -r -f manufacturer
读取厂家信息,总是返回：
Manufacturer is VEYE
2.2.2 model
./veye5_mipi_i2c.sh -r -f model
读取设备型号，比如：VEYE_MIPI_IMX335
2.2.3 version
./veye5_mipi_i2c.sh -r -f version
读取版本号，比如：
control version is 01.03 , isp version 01.00
2.2.4 timestamp
./veye5_mipi_i2c.sh -r -f timestamp
获取模组启动时刻开始计算的时间，循环递增，单位为毫秒。
2.2.5 factoryparam
./veye5_mipi_i2c.sh -w -f factoryparam
所有参数恢复默认值。
2.2.6 paramsave
./veye5_mipi_i2c.sh -w -f paramsave
保存参数。所有参数修改后，必须执行此命令，参数才会保存到flash中，掉电不再丢失。
2.2.7 reboot
./veye5_mipi_i2c.sh -w -f reboot
摄像头模组重启。
2.2.8 errcode
./veye5_mipi_i2c.sh -r -f errcode
获取摄像头错误码。正常情况下应该为0。
2.2.9 i2caddr
./veye5_mipi_i2c.sh -w -f i2caddr -p1 [new i2caddr] -d [old i2c addr]
./veye5_mipi_i2c.sh -r -f i2caddr -d [current i2c addr]
摄像机i2c地址，paramsave并reboot后生效。
2.2.10 i2cport
./veye5_mipi_i2c.sh -w -f i2cport -p1 [i2c port]
./veye5_mipi_i2c.sh -r -f i2cport
摄像机i2c端口，paramsave并reboot后生效。
