摘要
微机并行口的增强工作方式(EPP)可以进行双快速数据传输。介绍了并行口EPP方式的信号定义,寄存器、工作时序及利用微机EPP方式和差动线驱动器、接收器进行中远距离控制和数据快速双向传输的方法。设计了射线数字成像检测中CCD相机控制和数据传输的接口电路和采集软件,并进行了实验验证。
Extend parallel port of computer can fast data bi-directional transfer.The signals,register and work time sequence of EPP mode are introduced,the method of fast data bi-directional transmission and control using EPP mode and differntial line driver and receiver is introduced.Interface circuit and software of CCD data acquisition of digital radiographic testing system are designed,and the method is testified by experiment.
