摘要
在单片机中实现PWM控制技术的方法及其原理,分析单片机实现PWM功能几种方法的优缺点,分别介绍用单片机的PWM模块实现PWM功能、用程序模拟实现多路PWM功能、用定时器资源实现高分辩率PWM功能和用机外硬件实现PWM功能的方法,并分析这些的方法的优缺点。
To explore ways to achieve and the principles of PWM control technology in SCM,analysis of several technology to achieve the advantages and disadvantages of PWM function in SCM,and analysis focused on the ways to achieve highresolution PWM function with timer resources and the ways to achieve PWM function with SCM external hardware.
