4.具体摄像头的寄存器配置： 首先：make menuconfig ? ? ? ? ? ?Device Drivers------> Multimedia support -----> Video capture adapters -----> 选择相应的Camera驱动，比如GC0309 然后根据具体的需求到gc0309.c里面去按照手册配置寄存器。 主要是修改1.1里面前置和后置摄像头的引脚，地址，名字，以及一些参数。 及2和3里面初始化的配置 （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
