数字化仪与高级语言程序接口的设计方法

The Design of Interface for Digitizer and High Level Language Program

本文具体说明了主柱序与接口子程序之间的参数传递、设备驱动以及读取数据等问题和技巧,并给出了子程序的框架和关键部分语句,是一个可用性好的实例,也可作为设计其它串行外设接口时参考.

A method of interface for digitizer and high lever language program is introduced in this paper. It explains how to transfer the parameters between main program designed by high level language and interface subprogram designed by assemly language, how to design the device driver and get data from digitizer. Some key program statements are listed. It is a useful example of designing serice interface.
