摘要
介绍了基于通用串行总线USB2.0的数据采集卡接口设计,重点介绍了现场可编程门阵列程序设计和通用可编程接口波形描述符以及固件、应用程序的设计。通过对模块的验证,本设计可以正确地实现计算机和外电路之间的数据传输。
A data collection card interface design based on USB2.0 is introduced. FPGA（Field Programmable Gate Array） program and GPIF（General Program Interface） waveform, as well as the firmware program and application program are introduced. The design mentioned in this paper can achieve the correct data transmission between the computer and peripheral circuit through validating.
