中文摘要:AT89S5X系列单片机是目前使用最为广泛的8位单片机。主要对AT89S5X系列单片机在线编程的原理与应用进行了分析介绍。并利用AT89S52与PIC16F877A的在线编程功能,以AT89S52作为主处理器,PIC16F87X作为从处理器,设计一种PWM占空比可调闭环反馈控制器,可使控制精度大为提高。
外文摘要:AT89S5X series single chip is the most popular used 8 digital single chip at presented. This page mainly introduces and analyzes the principle and application of In System Programming(ISP) technology of the AT89S5X series MCU. Taking advantage of this feature, we give a design of PWM (pulse width module) close - loop back motor controller which is built on the primary processor AT89S52 and the second primary processor PIC16F87X. The design has greatly improved the control precision.
