摘要
VxWorks操作系统由于其高度的可靠性和优秀的实时性,而被广泛应用于嵌入式系统领域。本文在对VxWorks操作系统和USB2.0协议分析的基础上,对基于ZX2930 EVB2.0板的USB设备驱动进行了研究,并在此基础上对基于VxWorks的USB设备驱动进行了实现,成功建立了PC机与EVB2.0板之间的通信。实验结果表明,该驱动程序是稳健的、可靠的。
VxWorks operating system with high reliability and excellent real-time is widely used in the field of embedded systems. In the paper,first the VxWorks operating system and USB2.0 protocol are analysed. Second the USB device drivers based on the ZX2930 EVB2.0 board have been studied. Finally the VxWorks-based USB device drivers are realized and the communication between the Personal Computer and the board EVB2.0 is successfully established. The experimental results show that the driver is stable and reliable.
