摘要
本文介绍了使用AN2131SC芯片设计程控交换实验系统USB接口取代原有并行接口的完整过程,阐述了硬件、固件、设备驱动程序和应用程序设计等内容,为开发USB外设尤其是将并行接口外设改进为USB接口提供了范例。
This paper introduces the way using AN2131SC to implement USB interface to replace parallel interface in Stored Program Control switching system for teaching. It presents the design of hardware, firmware, device driver and client application, therefore providing an instance for USB peripheral development especially in replacing parallel interface with USB interface.
