C语言循环语句实现单片机延时函数

Implementation of Delay Function of Microcontroller Unit by Using C Loop Statements

延时是单片机教学中最常用的概念之一,因此延时函数是单片机控制程序中的一个重要函数。分别利用while循环语句、do-while循环语句、for循环语句以及while和for循环语句组合实现t ms延时点亮一个按照一定频率闪烁的LED灯,以此为例,总结了C语言循环语句实现单片机延时函数的方法,帮助学生在掌握C语言知识的基础上,增强了对单片机延时概念的理解,提高了教学效果。

Delay is one of the most commonly used concepts in microcontroller teaching , and delay function is an important function in the controlling programs of microcontroller unit .Take flashing LED lamps at a constant frequency lighted by t ms delay function, which realized using while, do-while, for, and combination of while and for loop statements, as an example, the delay functions of microcontroller C loop statements are summarized to help students enhance understanding the delay concepts of micro-controller unit based on the C knowledge.The results show the teaching methods are very good.
