摘要
介绍一种在嵌入式Linux环境下实现USB摄像头驱动的方法,它采用具有USBHost协议的接口芯片ISP1161,通过分析Linux设备驱动原理以及ISP1161和USB摄像头芯片组工作机制,实现了USB摄像头的嵌入式Linux设备驱动,并在基于IntelXscalePXA255的Sitsang平台上实现了基于USB等时传输模式的图像数据采集。
A method of implementing USB camera device driver for embedded Linux is introduced. Chip ISP1161 with USB Host is adopted. By analyzing the principle of Linux device driver and mechanism of ISP1161 and USB camera chipset, embedded Linux device driver for USB camera is implemented, and finally images data acquisition with isochronous transfer mode is realized in an embedded system based on Intel Xscale chip PXA255.
