摘要
在很多项目工程中,需要大量数据上传PC端或下载到终端,一般使用的PCI或ISA卡价格昂贵、安装麻烦、受计算机插槽数量等资源限制、可扩展性差,也可能跟其他插拔设备冲突,而使用串行通讯接口RS-232,传输速度慢。为了克服以上两者的不足,对Cypress公司的EZ-USB FX2LP芯片Cy7c68013a进行了研究,提出了基于该芯片的USB高速数据采集系统的设计方案。
In many engineering projects, large amounts of data are needed to be uploaded to PCs or downloaded to clients. However there are many demerits with the popular PCI and ISA, for example, exorbitant Price, troublesome installation, constraints of the sockets number, poor expansion, and potential conflicts with other pluggable devices and so on. At the same time, using serial communication interface RS-232 can always result in slow transmission rate, In order to overcome the above shortcom- ings, this paper researches on the EZ-USB FX2LP Cy7e68013a chip of Cypress Company and proposes a designing scheme of USB high data acquisition system based on the chip.
