| Abstract: | 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. |
