数据采集/波形发生系统是信息获取和传递的重要手段，是电子测控技术中至关重要
的环节。本系统采用虚拟仪器设计思想和USB2.0 总线通信技术，设计并完成了四通道高速数据采集器和两通道高精度波形发生器。本文主要从硬件和软件设计两个方而论述了数据采集/波形发生器的开发过程，重点阐述了硬件设计的原理、固件程序的设计思想、动态库的设计、应用程序的设计、固件下载驱动程序的开发以及inf 文件编写。
关键字：USB2.0,数据采集，固件，动态库
Abstract: The system of data acquisition and wave generator is an important method to acquire and transmit the information and a necessary part in measure-control technology. This thesis, adopting the idea of VI based on USB2.0, designed and realized a high speed acquirer with four channels and high precision wave generator with two channels. This paper discuss the process of designing and realizing data acquisition and wave generator primarily in the aspect of hardware and software, and the software includes the design of firmware program, Dynamic Link Library (DLL),application program, firmware-download driver development and encode of the inf file.
