摘　　要：设计了一种基于EZ-USBFX2实现的高速数据采集系统,系统采用GPIF控制模式,数据通过FIFO缓存后打包送给USB总线,打包传送时A/D仍持续工作,保证数据的高速不间断采集。给出了硬件设计方案,并对固件程序、驱动程序、应用程序编写过程中的关键性问题作了阐述。FX2是一个全面集成的解决方案,简化了电路的设计,提高了系统的可靠性,并实现了数据的高速采集与传输,非常适合应用于各种便携式测量仪器。A high-speed data acquisition system based on EZ-USB FX2 was designed. The system works in GPIF mode, after arriving in FIFO, the data was packed and sent to USB bus. In the process of packing, the A/D converter works simultaneously, which can assure high-speed and uninterrupted transmission. The hardware design and some critical problems in the programming of the firmware, device driver and client software were described in details. FX2 is a good integrated solution for the system to simplifies the design, improve the reliability and implement the high speed, so the system can be used for various apparatus.
