摘要
介绍了USB驱动的层次结构,给出实现基于ARM平台的针对Pixart公司PAC207-BCA芯片的摄像头驱动程序。结合具体开发实例,分析了针对PAC207-BCA芯片的摄像头驱动程序的主要函数实现。最后在Embest S3CEB2410开发板上加载交叉编译过的驱动模块,给出上层测试程序的主体结构。
The hierarchical structure of USB driver is simply described, the webcam driver of Pixart Company＇s PAC207-BCA chip according to the realizetion ofARM platforrn is analyzed. Finally, the cross-compiled USB webcam driver is planted into the development board of Embest S3CEB2410 and is tested. And the main structure of the testing program is presented.
