基于USB的16位简易数字信号源设计与实现

Design and implementation of simple 16 bit digital signal source based on USB

针对许多数字产品开发调试中,需要任意序列的数字信号,设计并实现一种基于USB技术的简易16位数字信号源系统。系统由计算机产生需要的数字序列,通过USB总线技术,将数据输出。系统硬件接收USB数据,并进行必要的转换处理,最终得到可以作为调试源的数字序列。最后,从硬件、固件、驱动程序、应用程序等4个方面阐述了设计思想及实现方法。

For many digital product need an arbitrary sequence digital signal source when they are developing and debugging, a simple 16 bit digital signal source based on USB technology is designed and implemented. The arbitrary sequence is created by PC and are trans- mitted through USB interface. System hardware receive USB data and complete serial to parallel conversion. Finally, digital sequence is gotten, which could used as debug source. The design and implementation method is illustrated in hardware, firmware, device driver, application programme etc.
