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.
在很多項目工程中,需要大量數據上傳PC耑或下載到終耑,一般使用的PCI或ISA卡價格昂貴、安裝痳煩、受計算機插槽數量等資源限製、可擴展性差,也可能跟其他插拔設備遲突,而使用串行通訊接口RS-232,傳輸速度慢.為瞭剋服以上兩者的不足,對Cypress公司的EZ-USB FX2LP芯片Cy7c68013a進行瞭研究,提齣瞭基于該芯片的USB高速數據採集繫統的設計方案.
재흔다항목공정중,수요대량수거상전PC단혹하재도종단,일반사용적PCI혹ISA잡개격앙귀、안장마번、수계산궤삽조수량등자원한제、가확전성차,야가능근기타삽발설비충돌,이사용천행통신접구RS-232,전수속도만.위료극복이상량자적불족,대Cypress공사적EZ-USB FX2LP심편Cy7c68013a진행료연구,제출료기우해심편적USB고속수거채집계통적설계방안.
In many engineering projects, large amounts of data are needed to be uploaded to PCs or downloaded to clients. How-ever 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 Cy7c68013a chip of Cypress Company and proposes a designing scheme of USB high data acquisition system based on the chip.
