摘　　要：在实现按键去抖动、定时检测、定时扫描等控制中,经常使用精确延时程序。通过Proteus仿真比对以及对延时程序的研究,总结了软件延时程序中延时时间的计算公式和办法,并给出了精确延时程序的设计方法。The software delay especially the accurate delay program is commonly used to the MCU control such as the keys shaking release,regularly checking and scanning.A design approach of the accurate delay program is presented based on the summary of the delay time calculation formula and realization in the delay program with the Proteus simulations of different delay programs.
