摘要
数据采集系统的设计以FT245BM芯片为核心,数据流通过USB传输。该系统通过AD采集外部信号,在FPGA中形成数据流,经FT245BM封装后通过USB上传至PC机。同时在PC机上设计的人机界面十分友好,交互性强。系统性能测试显示,采集系统实时传输速率可达1.5MBps以上。结果证明,整个系统高速稳定,安全可靠,有很高的实用价值。
Designing of a data acquisition system in which the transmission of the data stream through USB（Universal Serial Bus） based on FT245BM.The external data was acquired by AD and formed into data streams in FPGA.Then the data streams were transmited by FT245BM,which uploaded to PC through USB at last.At the same time the software interface was very friendly and highly interactive.System performance testing displayend that the real-time transfer rate of acquisition system exceeded 1.5MBps.The experiment testified that this system was high-performance,stable,safe,and was of great practicality.
