摘　　要：讨论了基于USB2.0的数据采集卡中固件程序的开发。介绍了该数据采集卡的硬件设计方案,并对用于实现USB接口功能的接口芯片CY7C68013A进行了简单的介绍;然后根据该芯片的固件程序框架的结构,介绍了固件程序的开发。This paper discusses the development of the firmware program and the application program in the data acquisition adapter based on USB2.0. Firstly, it simply introduces the design of the data acquisition adapter and especially the interface CYTC68013A chip supporting the USB; then according to the frame structure of its firmware program, it introduces the development of its firmware program in detail; finally, it introduces the design of driver program and the realization of the application program. It proves by practice that this adapter not only has high sampling accuracy, high velocity and good reliablility, but also has the characters of small volume, convenience and so on.
