摘要
高速USB数据采集系统的设计严格遵循USB2.0协议,实现了主机和测试设备之间简单、快速、可靠的连接和通信。该文介绍了这种数据采集系统的硬件组成、驱动程序和固件程序的设计以及采用虚拟仪器软件LabWindows/CVI在VISA技术上开发应用程序的设计方法。
The design of this high-speed USB DAQ system abides by protocol USB2.0 so strictly that it can achieve a simple, fast and reliable connection communication between the host and USB devices. This paper introduces the composition of hardwares of this system, the design of its driver and firmware programs and the method by which the virtual instruments software Labwindows/CVI is adopted to develop VISA-based application programs.
