是protel的讲义，应该有利于大家的学习

实验采用七段码LED设计（数码管），显示直观；采用定时器中断，计时更准确；功能齐全，可随时启动、停止、清零，后者智能化程度更高。-Seven-Segment LED code using the experimental design (digital control), visual display using timer interrupt, a more accurate time functions, may at any time to start, stop, cleared, and the latter an even higher degree of intelligence.

这是一本很好的单片机实验指导书，是初学者的指导资料。-This is a good experiment SCM guide book is a guide to beginners.
