摘要
USB总线是一种快速、双向、同步、低成本、动态可连接的串行总线,其驱动程序是Linux内核的一个重要组成部分。随着Linux操作系统的广泛应用,特别是嵌入式设备的大量出现,USB驱动程序的编写越来越显得重要了。本文实现了基于DSP平台的USB从机固件开发以及基于ARM下嵌入式linux的USB主机设备类驱动开发。
USB is a serial bus which is fast and bidirectional, synchronal, cost-effective and hot-plug supported, and its driver is an essential part to Linux kernel. As the Linux operating system is applied more and more extensively, the importance of USB driver also become more and more significant. This paper presents the implementation of the firmware for USB slave based on DSP platform and the USB host-class driver based on embedded Linux.
