摘要
增强型并行口 EPP与标准并行口 SPP兼容 ,但可通过数据线双向传送数据 ,并且达到接近于 PC机 ISA总线的数据传输率。本文详细讨论了 EPP接口特性 ,并使用 CPL D设计虚拟仪器的 EPP接口电路 ,给出了用 L ab Windows/CVI编写的
The Enhanced Parallel Port(EPP) is compatible of the Standard Parallel Port(SPP) .Ittransmits data on bi- direc- tion by its data bus,its rates of data transmitis approximate to one of PC′s ISA bus.In this paper,it is discussed that there are main features of EPP interface and to design a EPP interface forvirtual instruments based CPL D.Itis provided with EPP interface functions in L ab Windows/CVI.
