The Controler Development Of Mechanical And Electrical Products Based On AT89C55WD Single Flat Machine

This artical designs the controller of Machine-Electronic Products Based on Single Chip Computer AT89C55WD,which can be used in the intelligence and some industrial electronic equipments melts and upgrading.It is economical, small in bulk , steady, etc, which can both economize the cost and make the full use of resources, as well as enhance on the reliability of the system,as used in the design of the embed system.The digest elaborates the development of Single Chip Computer AT89C55WD with CMOS 8ytes in high function, which is based on low voltage.This design has the function of simulant and digital input-output which uses standard keyboard as input equipment and the display of liquid crystal, have printer interface and 485 communication network functions.Author has carried out complete circuit design in paper work for this controler, have allocated as far as possible human nature the man-machine interface that melts , have designed corresponding software system.
