一种利用PIC实现PWM控制的方案

The Project to Achieve PWM Control Using PIC

本文介绍了一种使用PIC16F873/ 876微控制器的单片机的闭环控制系统 ,详细介绍了PIC单片机的特点以及其驱动PWM调速芯片进行电机控制的原理。给出了系统的电路设计图和相应的软件设计。实验中由于PIC16F系列可重复擦写 。

One closed loop control system using micro-controllers chips such as PIC16F873/876 was introduced and attributes of PIC and PWM Motor Driver were described.The circuit design of the system and corresponding software design were also demonstrated,including control principles.Since PIC16F can be rewritable,it’s convenient to adjust commands to establish PIC controlling.
